Principles of Evolution
Chapter 10-12
Standard:
Be:
The student will demonstrate an understanding of biological evolution and the
diversity of life.
Indicators:
Be.1:
Summarize the process of natural selection.
Be.2:
Explain how genetic processes result in the continuity of life-forms over time.
Be.3:
Explain how diversity within a species increases the chances of its survival.
Be.4:
Explain how genetic variability and environmental factors lead to biological
evolution.
Be.5:
Exemplify scientific evidence in the fields of anatomy, embryology,
biochemistry, and paleontology that underlies the theory of biological
evolution.
Be.6:
Summarize ways that scientists use data from a variety of sources to investigate
and critically analyze aspects of evolutionary theory.

Evolution is change in the genetic make-up of a species over time.
a. Change in heritable traits of biological populations over successive generations.
b. Descent of species by modification of heritable characteristics due to natural selection.
Evolution occurs in patterns
a. It is not random
b. Interaction between species is key to survival
c. Species become extinct
New species arise when populations are isolated.
a. Populations, not individuals, evolve
Darwin proposed natural selection as a mechanism for evolution.
a. Natural selection acts on existing genetic variation and is the main mechanism for
evolution.
b. There are other mechanisms.
i. Gene flow
ii. Genetic drift
iii. Sexual selection
Evidence of common ancestry is both directly and indirectly observed.
a. There are multiple sources of support.
New technology is providing more evidence that supports our understanding of evolution.
Genetic variation in a population increases the chances of survival.
a. Genetic variation comes from many sources.
Fossils are a record of the past
The origin of life remains a puzzle

Identify the observations that led Darwin to conclude that species evolve
Relate the process of natural selection to its outcome
Compare artificial selection to natural selection
Describe how the fossil record supports evolution
Understand how DNA sequencing is used as evidence for evolutionary ancestry
Summarize the major sources of evidence for evolution
a. The fossil record, homology, molecular and genetic evidence
Relate current observations of the natural selection process as driving change in species, such as
the use of pesticides and antibiotic resistance.
Describe the significance of genetic variation within a population.
Explain the ways natural selection can change the distribution of a trait in a population
