Oil Painting of Abbot Gregor Mendel
His life was remarkable: a 19th. century friar and high school science teacher whose brilliant experiment with ordinary
peas revealed the laws of heredity. Regarded as the father of modern genetics, Gregor Mendel and his work are
presented in the fascinating Gregor Mendel: Planting the Seeds of Genetics at The Field Museum in Chicago.
Original manuscripts, photographs, and scientific instruments evoke the world of scientists in the 1800s and early 1900s.
You’ll see most of the only remaining artifacts from the life of this great scientist. Plus, hands-on interactive displays
allow you to conduct Mendel’s famous pea experiment yourself.
Trace Mendel’s influence on the rise of genetics and meet “modern Mendels”—scientists on the cutting edge of the
field today. Throughout the exhibition, contemporary works of art that are inspired by genetics reflect the spirit, insight,
and curiosity that drive scientists. Originally ignored by the scientific community, Mendel’s wondrous discoveries and
his dramatic story are given new life at The Field Museum.

Corresponding Illinois Learning Standards (ILS)
The Illinois Learning Standards (ILS) define what all students in all Illinois public schools should know and be able
to do in the seven core areas as a result of their elementary and secondary schooling. The classroom assessments are
resources to help teachers determine local performance expectations for the Illinois Learning Standards (ILS) at each
grade level. For more information on the ILS visit www.isbe.state.il.us/ils/Default.
Use of the materials in this Educator Guide in combination with a field trip to the exhibition will help you link
learning experiences to the following Illinois Learning Standards (ILS). Teachers will need to identify descriptors and
benchmarks to individual lesson plans, larger units of study, and to specific subject area. This exhibition, while suitable
for all students regardless of grade level, maps closely to concepts studied in later elementary, middle school, and high
school.

Naturalist: A naturalist is a person who studies nature (including plants and animals) and natural history (how plants
and animals evolve).
Botany: Botany is a specialized branch of biology
dealing with plant life.
Monastery: A monastery is the habitation of monks,
derived from the Greek word for a hermit’s cell.

Meteorology: Meteorology is the scientific study of
the atmosphere that focuses on weather processes and
forecasting.
Meteorological Observations Taken in Brno, October
1878 by Gregor Mendel
Physics: The study of how objects (from the very tiny to the very big) behave.
Greenhouse: Structure used for growing plants. Natural sunlight comes in through glass or plastic panels and the
temperature and humidity is controlled to provide ideal growing conditions.
Plant Hybrid: The offspring of two plants of different species or varieties of plants. Hybrids are created when the
pollen from one kind of plant is used to pollinate an entirely different variety, resulting in a new plant altogether.
Preformation: A theory (popular in the 18th century and now discredited) that an individual develops by simple
enlargement of a tiny, fully-formed organism that exists in the germ cell.
Evolution: Evolution is the accumulation of inherited changes in populations of organisms over the course of
generations. Evolution explains how what we see today may differ from the past. Evolutionary theory explains the
diversity of life through descent with modification.
Theory: A well-substantiated explanation of some aspect of the natural world; an organized system of accepted
knowledge that applies in a variety of circumstances to explain a specific set of phenomena; theories can incorporate
facts and laws and tested hypotheses.
Pangenesis: Pangenesis was Charles Darwin’s hypothetical mechanism for heredity, an early and inaccurate idea that
acquired characteristics of parents are blended and transmitted to their offspring.

Words to know
DNA: DNA—DeoxyriboNuckeic Acid—is the instructions for building parts of the cell. The information in DNA is
stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Natural Selection: Natural selection is the basic Darwinian
explanation for what drives evolution: organisms that are better adapted
to their environment are more likely to survive and therefore more likely
to pass along their characteristic genes.
Artificial Selection: Artificial selection is evolution guided by humans,
which encourages the breeding of certain traits over others.
Cytology: The study of the structure and function of a cell.
Chromosomes: Packages of compact DNA. Each human cell holds 46
chromosomes.
Eugenics: Eugenics is a misguided branch of study devoted to the
“improvement” of the human race. Forms of eugenics led to the
sterilization of “defective persons” immigration restrictions against the
“socially inadequate”, and Nazi Germany’s policies of “race hygiene.”

Lysenkoism: Lysenkoism was a Soviet doctrine under Stalin, which
argued that an organism’s heredity make-up was determined by its
environment only, and that in this doctrine, genes did not exist.
Human Genome Project: The Human Genome Project is a government
funded and international research project to map each human gene and
to completely sequence human DNA. Estimates suggest that there are
approximately 20,000-25,000 genes in human DNA.

Introduction to the Exhibition
“It’s just a little trick, but there is a long story connected with it in which it would take too long.” G. Mendel to C.W. Eiching
(Eiching visited Mendel in 1878; his record of the meeting was published in an article “I talked with Mendel” in 1942.)
Heredity
Heredity is how traits get passed from parents to offspring in animals and plants. It’s why some “grey squirrels” are black,
why the corn we eat is plumper than what the Pilgrims grew, and why Tiger Woods has hazel eyes. Its outward signs are
obvious, but scientists from Aristotle onward could only speculate about its internal causes.
In 1865, a scientifically inclined priest changed all that. Through his experiments with pea plants, Father Gregor Mendel
outlined the basic laws of heredity—which were then overlooked for thirty-five years. When his findings were finally
embraced in the early 1900s, the science of genetics was born. We invite you to meet Gregor Mendel, ponder the riddle
he unraveled, and explore the advances made by his scientific “descendants.”
It aims to unravel the “little trick” and “long story” of Mendel’s discovery. Behind much of today’s scientific research lie
the groundbreaking theories of “the father of genetics,” Gregor Mendel. This friar, naturalist, agriculturalist, and botanist
undertook revolutionary experiments that have shaped our modern understanding of genes, crossbreeding, and heredity.
The Field Museum’s new exhibition uses a compelling combination of rare artifacts and interactive technology to tell
the story of Mendel’s life and research in the 1800s, chart the rise of classical genetics in the 1900s, and highlight the
work of Mendel’s present-day “heirs” who use genetics to study evolution, systematics, and biodiversity.
This exhibition presents an extraordinary collection of Mendel’s notes and correspondence, scientific instruments,
botanical specimens, seminal texts annotated in Mendel’s own hand, photographs and an oil painting of Mendel, and
related objects from Mendel’s home and laboratory, the Augustinian Abbey of St. Thomas in Brno, Czech Republic.

The exhibition brings to life other pioneering discoveries in
genetics through key publications, scientific illustrations, and
biological specimens. The exhibition also illuminates current
research with specimens, laboratory equipment, DNA sequence
data, and other relevant objects. Throughout the exhibition,
contemporary art inspired by genetic research underscores
the curiosity about life and nature that drives both artists and
scientists.
In addition to these remarkable artifacts, engaging interactives
encourage visitors to participate in hands-on explorations of
Mendel’s work, recreate his famous pea experiments, and learn
the fundamentals of genetics.

Pre Mendel
Illustration: Greg Mercer
As far back as 10,000 years ago, Neolithic farmers
were selecting plants and animals with favored
traits for reproduction—the highest-yielding
vegetable, the sweetest fruit, the fastest horse,
or the fattest cow. What we call heredity was
recognized, but its causes were a mystery.
Seven Pairs of Contrasting Traits
Greek philosophers speculated about heredity
as far back as 400 BC, suggesting it worked as a
blending of particles or fluids from each parent.
By the seventeenth century, improved microscopes
provided a closer look at reproduction, but could
not penetrate the secrets of heredity. The leading
theory at this time, “preformation,” held that an
organism contained all of its future descendants,
encased in increasingly miniature forms.
Botanists began studying the characteristics of plant hybrids in the 1700s, noting similarities between parents and
offspring. Meanwhile, livestock breeders in England and Europe were using selective breeding to get woollier sheep and
meatier cattle. Naturalists of this era probed life under microscopes and conducted breeding experiments, both to track
traits across generations and to explore evolutionary connections among species. But most of them still promoted a
“blending” model almost identical to the ancient Greeks’.
The great naturalist Charles Darwin bred plants and animals to study species variation. He knew that a mechanism for
heredity was essential to his theory of evolution (belief that all living things are related), and he too promoted a blending
theory (which he called “pangenesis”). But he was dissatisfied with it, and admitted in On the Origin of Species
(1859) that “the laws governing inheritance are quite unknown.” What he didn’t know then was that all of evolution’s
adaptations involve a change in DNA.
As he wrote these words, however, an inquisitive friar in a garden in Central Europe was conducting experiments that
held the answer to the riddle and the eventual revolutionary understanding of genetics and DNA.

Pre-Activities
1.View Video Who is Charles Darwin at http://www.pbs.org/wgbh/evolution/educators/teachstuds/svideos.html. Ask
students to make notes of points that interest them and anything that may need more explanation. Break into small
groups for discussion of issues.
2. Darwin’s revolutionary theory of evolution challenged the pervading belief of divine will and profoundly changed the
way the world was viewed. Human curiosity about the natural world continuously challenges popular opinions and
scientific theories. Divide the class into groups and assign as topics for investigation some once prominent scientific
theories. Suggested topics can include the earth is flat; geocentrism (the sun orbits the earth); Dante’s explanation of
the four elements, fire, earth, water, and air; divine will, preformation and pangenes. Have students research the major
components of these “theories”, the period of history in which they were prevalent, and how they may have fallen
out of disfavor. Present findings to class.
3. Have students create a narrative entitled “My Life in Science.” What kind of scientist would they be and why? What
interests in the natural world led them to this field? Did they make any revolutionary discoveries? Visit http://www.
nhm.ac.uk/kids-only/get-the-facts/ologist/ for some inspiration.
4. Query the class about artificial selection and natural selection. What is the difference between the two? What
examples in our modern life can students give of artificially selected life forms and naturally selected life forms? How
do they support their theories? Some helpful websites for this discussion include:
http://en.wikipedia.org/wiki/Artificial_selection,
http://www.sparknotes.com/biology/evolution/naturalselection/section3.rhtml,
http://www.nhm.org/exhibitions/dogs/evolution/selection/natural.html, and
http://www.learner.org/channel/courses/essential/life/session5/closer1.html.
Field Trip Activities
1. Review panels in this section: Early Scientists, Crossbreeding, and Charles Darwin. Have students identify and define
preformation, blending, and pangenesis, the various models used to describe heredity before Mendel.
2. Encourage students to visit the exhibition Inside Ancient Egypt. This culture and civilization thrived due to its selective
breeding and domestication of wild grains (wheat). What can students discern about the connection between plant
domestication (artificial selection) and its relationship to culture and civilization? Make notes on their findings for
further discussion in class.
3.Visit The Field Museum’s exhibition Plants of the World. This exhibition contains 5 different botanical scenes. Divide
the class into 5 groups and assign a botanical scene to each group. Have students identify and sketch the various
species they observe. How many different life forms can they identify?
4.Visit the World of Mammals exhibition on the main floor of the Field Museum. Spend time in the “Carnivore Corner”
where the relatives of domestic dogs and cats reside. In pairs, identify and locate two relatives of dogs and two relatives
of cats.

Post-Activities
1.Visit the PBS Evolution website and read about Darwin and evolution at http://www.pbs.org/wgbh/evolution/
Watch the video “Darwin’s Dangerous Idea” Ask students to write a few paragraphs summarizing the importance of
Darwin’s dangerous idea.
2.View The National Center of Science Education’s website to see what some major religious organizations are saying
about evolution. http://www.ncseweb.org/resources/articles/7445_statements_from_religious_org_12_19_2002.
asp. In small groups, randomly select one of the statements from the represented religious organizations and read and
discuss the content. Create a chart highlighting the major ideas of the statements. Ask students to present findings in
class. What are the similarities or differences among the different organizations?
3. Cats and dogs were some of the first animals humans selectively bred.Visit National Geographic at http://www7.
nationalgeographic.com/ngm/data/2002/01/01/html/ft_20020101.1.html and read about the evolution of dogs
from wolves. Also visit http://www.pbs.org/wgbh/nova/dogs/world.html to interactively hone your knowledge
about the variety of dog breeds around the world.
4. Research the history of wheat online at http://www.farmdirect.co.uk/farming/stockcrop/wheat/wheathist.html
and http://library.thinkquest.org/5443/whistory.html. Combine this new information with experiences at Mendel
and Inside Ancient Egypt Exhibition to explore as a class how knowledge of heredity (i.e. which grains would be most
productive, nutritious, etc.) interacts with culture and civilization.
5. Ask students to create through illustration a crossbred or blended plant or animal using an illustration.

Answers to Guiding Questions
1. Charles Darwin was an English naturalist fascinated by nature. His keen observations and explorations of the natural
world led to his most famous work On the Origins of Species. Origins reflected his observations that all living things
are related and introduced the scientific theory of natural selection. This work influenced scientific, political, religious,
and cultural revolutions throughout the world.
2. A botanist is a specialist in a branch of biology dealing with plant life. A naturalist is a person who studies nature
(including plants and animals) and natural history (how plants and animals evolve).
3. Pangenesis was Charles Darwin’s hypothetical mechanism for heredity, an early and inaccurate idea that acquired
characteristics of parents are blended and transmitted to their offspring. Preformation was a popular theory in the
18th century that all parts of an organism exist completely formed in the germ cell and develops only by increasing
in size.
4. Evolution is the accumulation of
inherited changes in populations
of organisms over the course of
generations. Evolution explains how
what we see today may differ from
the past. Evolutionary theory explains
the diversity of life through descent
with modification.

5. Natural selection is the basic
Darwinian explanation for what
drives evolution: organisms that are
better adapted to their environment
are more likely to survive and
therefore more likely to pass along
their characteristic genes).
6. Selective breeding is the selection
Plans for the Greenhouse Constructed for Mendel’s Experiments
of certain seeds or animals for
reproduction in order to influence the traits inherited by the next generation. Mendel selectively bred pea plants in
his experimentations. Domestication is the process of genetically adapting an animal or plant to better suit the needs
of human beings. Agriculture is the domestication of plants.
7. Wild plants were transformed into crops by Neolithic peoples through artificial selection. Artificial selection is
evolution guided by humans, which encourages the breeding of certain traits over others. Though they did not possess
the knowledge of genes and heredity or the technology we do today, their methods relied informally on observation,
theories, and experimentation.
8. Heredity is the passing of traits from one generation to the next. A trait is a notable feature or quality.

Mendel: The Man and the Scientist
The son of poor tenant farmers in the Austro-Hungarian Empire, Johann Mendel was
introduced early to science. From his father he learned to grow plants and graft fruit
trees, and his grade school curriculum included natural science and agriculture. Johann’s
prospects were limited, but the priesthood offered a stable livelihood and a scholarly life.
Gregor Mendel
In 1843, at age 21, he joined the Augustinian Monastery in Brünn, taking the name
Gregor in the Abbey of St. Thomas, of which he became the abbot in 1867. At the
beginning of the 19th century, Brünn, capital of the province of Moravia—then a region
of the Austrian-Hungarian empire—was a culturally active, multi-lingual city. Mendel,
who took part in the social and cultural life of the town, gained titles such as that first of
Vice-President, and then President of the local Mortgage Bank, the Hypotheque Bank. He
was especially known for his activity as a teacher, for his interest in meteorology and in
the breeding of bees.
The Abbey was a very supportive environment for Mendel’s scientific inclinations due partially to the AustroHungarian empire 1780s policy forcing religious institution to serve the State as well as the Church. The Abbey became
a vibrant center of research, whose friars were active in the sciences, linguistics, literature, and philosophy. Many were
distinguished scholars in their chosen fields, and most taught at nearby high schools and universities. After a year of
parish work, Mendel spent two years teaching mathematics and science at local high schools—before returning to
school in 1851, at age twenty-nine. He attended the University of Vienna for two years, studying with noted physicists,
mathematicians, and botanists.
Mendel’s own systematic experiments on pea plants were started in 1856 in the Abbey’s greenhouse. In 1865 Mendel
presented his seminal paper on pea hybrids, Experiments in Plant Hybridization, and in 1866 this was published in the
proceedings of the local Society for Natural Sciences.Yet, over fifty years later, the monk who experimented on pea hybrids
was to be acclaimed as the father of classical genetics. The concepts he established in 1865 came to be known universally
as Mendel’s laws of heredity, and the man himself came to be regarded as the “father of genetics”.
This exhibition goes beyond the romantic myth of the isolated friar undertaking incongruous experiments with peas; it explores
“Mendel the man”, and what led to the formulation of his laws of heredity.

Answers to Guiding Questions
Monastery vs. Abbey
Strictly speaking a monastery is the dwelling of monks, and a
friary that of friars. In modern usage, monastery has become
commonplace designation for dwelling places of any religious
communities, but it still carries the connotations of isolation and
cloister, which was not and is not true for all religious orders. “Abbey”
generally designates a monastery (a community of monks) under
the leadership of an abbot. Mendel’s abbey was an exception in that it
was a community of friars under the leadership of an abbot.
2. Moravia is an historical region of the Eastern Czech Republic. The
Austro-Hungarian Empire, also known as Austria-Hungary, or the
Mendel with Friars
Hapsburg Empire, was ruled by the Habsburg monarchy from 1867
to 1918. Austria-Hungary extended over most of central Europe. It was comprised of the modern day countries of
Austria, Hungary, Slovakia, and the Czech Republic, as well as parts of present-day Poland, Romania, Italy, Slovenia,
Croatia, Bosnia and Herzegovina, and the Federal Republic of Yugoslavia.
© Stepan Bartos
1. Friar vs. Monk
A friar is a member of one of the “mendicant” orders (originally forbidden to own property, dependant on
donations—begging—for a living). The four great orders of friars are the Dominicans, the Franciscans, the Carmelites,
and the Augustinians. The word friar is to be carefully distinguished in its application from the word monk. For the
monk retirement and solitude are undisturbed by the public ministry, unless under exceptional circumstances. In the
life of the friar, on the contrary, the exercise of the sacred ministry is an essential feature, for which the life of the
cloister is considered as but an immediate preparation [from New Advent Catholic Encyclopedia]. From its founding in
1256, the Augustinian order, to which Mendel belonged, focused on education and scientific study as well public
ministry and missionary work.
3. Science is a way of knowing about the natural world based upon observations, hypotheses, and facts that are testable
and can be confirmed or disproved using scientific technique. A scientific theory is a well-substantiated explanation
of the natural world utilizing many confirmed observations, laws, and successfully verified hypotheses. A scientific
hypothesis is a testable statement or observation of some aspect of the natural world.
4. In genetics, hybridization is the process of mixing different species or varieties of organisms. Gregor Mendel used
artificial cross-pollination to hybridize the pea plants in his experiments.
5. As of now, we have no record regarding Mendel’s thoughts regarding the relationship between his religious beliefs and
his scientific endeavors.
6. Like many scientists of his day, Mendel did not specialize in just one subject—he was an astronomer, meteorologist,
and physicist, as well as an experimental botanist. These diverse interests were united by the mathematical principles
that Mendel applied to them. Mendel’s record of meteorological variations demonstrates his meticulous attention
to his data. Mendel’s plant-breeding experiments were rooted in the same principles as his meteorological work: the
observation of natural phenomena, and the statistical calculation of variations.

enes are the basic biological units of heredity. They are composed of DNA. Heredity is the passing of traits from
one generation to the next. A trait is a notable feature or quality.
8. M
endel began his experiments by selecting twenty-four varieties or peas, which he grew for two years to assure that
they “bred true”— with subsequent generations identical to the original plants. Once confident of their purity, he
began to cross-different varieties. Mendel grew his peas in a specially built greenhouse, and in garden plots on the
abbey grounds.
9. M
endel proposed that traits result from “factors” passed by parents to successive generations according to set ratios.
The factors for any trait come in pairs—one from each parent. These factors are sometimes expressed and sometimes
concealed, but never lost. During reproduction, the factors separate and pass on with equal frequency to the next
generation, and they travel independently of any other factor. Later scientists labeled these ideas the “principle of

SECTION THREE
Rediscovery of Mendel, Rise of Classical Genetics to DNA
While Mendel’s paper languished, unread, in libraries across Europe and the US,
scientific inquiry into the mysteries of heredity carried on. As hybridists continued
their experiments, another branch of heredity science sprouted: cytology, the study
of the structure and function of the cell. Thanks to improved microscopes and
better techniques for staining cells, scientists were finally able to probe an amazing
new world—one that would ultimately reveal the mechanics of what Mendel had
proposed.
© Stepan Bartos
In 1900, three European botanists brought Mendel’s pea paper to light. Carl
Correns, Hugo de Vries, and Erich von Tschermak referred to Mendel’s Versuche
in their papers on hybridization. Wilhelm Focke’s mention of Mendel in his
bibliography led these experimenters—directly or indirectly—to Mendel’s paper
and their publications at last pulled the veil of obscurity from Mendel’s findings.
Mendel’s Microscope
While the “Mendelian” breeders continued charting hereditary patterns in pea
plants, roosters, and rabbits, the cell biologists, working with simple organisms like
sea urchins—which had few, easily visible chromosomes—were making stunning
new discoveries through their microscope lenses. The chromosomes’ patterns of
division suggested to some scientists that they might be the carriers of heredity,
and by 1903 the cytologists made the connection between chromosomes and
Mendel’s laws.
Deoxyribonucleic acid—originally called nuclein—was discovered in 1869, just three years after Mendel’s pea paper. By
the mid-1940s DNA was largely accepted as the carrier of genetic information, but how it copied itself, to pass on the
hereditary “code,” was unknown. The molecular structure was the key, and by the early fifties a race to determine that
structure was on. Two pairs of scientists working in England—competing teams joined in an uneasy collaboration—won
the race in 1953.
The structure of DNA is regarded today as the most important biological discovery since Mendel, and its reception by
the scientific community would have been familiar to the friar. Watson and Crick’s paper was largely ignored—although
for only a few years, not decades. The double helix theory was eventually confirmed, marked a new era in genetics,
rooted in Mendel’s work, and enabling the next generation to make more dramatic discoveries about the natural world.

a delicious candy model.
3. Drawing from the family trees made in the Pre-Activity, ask students to explore how DNA can fill in gaps or
enrich the knowledge they have about their own heredity and genetic past.Visit http://www.pbs.org/wnet/aalives/
index.html for PBS’s website on the series African American Lives. Discover how modern genetics can affect our
knowledge and perception of our familial and genetic past.
4. Research the current debate concerning genetically modified foods. Divide students into two groups. One group
will research the possible risks or dangers of genetic engineering and the other will research possible benefits. Choose
spokespersons from each group to argue their findings.
5. Divide the class into small groups and ask them to research the ways on which politics influences science. Assign
topics such as Copernicus, Lysenkoism, Nazi eugenics, and stem cell research, or the Human Genome Project. In
what ways has or does politics control and utilize scientific knowledge and information? Present findings to the class
and compare and contrast similarities and differences among the topics.
6. Have students construct a graphic organizer to illustrate what they have learned from the exhibition. Why is this topic
important to me? How is this issue related to what we are studying? What new vocabulary did I learn? What else do I
need to know about this issue?
8. Profile a “Modern Mendel,” a present-day scientist who applies Mendel’s theories to fields such as conservation,
biological anthropology, and evolution.Visit the Field Museum biodiversity webpage and find a scientist to profile.

Answers to Guiding Questions
1. Cytology is the study of cell anatomy and function. Chromosomes are packages of compact DNA. Each human cell
holds 46 chromosomes.
2. Eugenics is a misguided branch of study devoted to the “improvement” of the human race. Sinister forms of eugenics
led to the sterilization of “defective persons”, immigration restrictions against the “socially inadequate”, and Nazi
Germany’s policies of “race hygiene.”
3. Lysenkoism was a Soviet doctrine under Stalin, which argued that an organism’s heredity make-up was determined
by its environment only and that genes did not exist. Nature versus nurture is a shorthand expression for debates
about the relative importance of an individual’s genetic qualities (nature) versus personal experiences (nurture) in
determining or causing individual differences in physical and behavioral traits.
4. James Watson and Francis Crick of Cambridge University, and Maurice Wilkins and Rosalind Franklin of King’s
College were the teams of scientists credited with discovering DNA’s double-helix structure in 1953.
5. DNA—DeoxyriboNuckeic Acid—are the instructions for building parts of the cell. The information in DNA is
stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). The double
helix is one of the greatest scientific discoveries of all time. First described by James Watson and Francis Crick in
1953, DNA is the famous molecule of genetics that establishes each organism’s physical characteristics.
6. Human activities influence evolution in many ways.
During the last 50 years, over 500 species of insects have
become resistant to pesticides. Our destruction of habitats
has endangered species and reduced populations have
declined so that their genetic diversity has decreased and
their ability to adapt to environmental changes. Our use
of technology is allowing us to alter the evolution of
many species besides our own. We have a responsibility to
continue to learn how to use our knowledge of evolution
wisely to minimize the deleterious effects we have on the
biosphere (The portion of Earth and its atmosphere that
can support life).
© Field Museum GN90796d
7. The Human Genome Project is a government funded
and international research project to map each human
gene and to completely sequence human DNA. Estimates
suggest that there are approximately 20,000-25,000 genes
in human DNA.

dedicated to the genetic analysis and preservation of the world’s biodiversity. Each year this lab collects more than 70,000
DNA sequences, enabling Field Museum scientists to study plants and animals from around the world.
From birds to mushrooms to sharks, scientists investigate questions on a multitude of topics. How diverse are the warblers
of Central Africa? How many species of fungi are in that soil sample? Which male sired that shark pup? The methods
used to address these questions are remarkably similar across projects. Essentially, scientists compare DNA among
individuals, species, genera, or even at higher taxonomic levels. Thanks to the Pritzker Lab, scientists other researchers are
solving key questions about relationships among the diverse forms of life on Earth.
