Time Period Walk Through (handout)
Mesozoic- age of dinosaurs, ended when asteroid/meteor hit the
planet, rocky mountains formed, etc.
Cenozoic- age of mammals
Paleozoic- first large “explosion” of life, increased diversity
Pre-Cambrian- beginning of Earth

A. Cenozoic
Q. What is the order for the time Periods from oldest to youngest?
A. Pre-Cambrian, Paleozoic, Mesozoic, Cenozoic

variety
Animals have become increasingly complex and diverse throughout
Earth’s history.
Pre-Cambrian- mostly single celled organisms and simple multi celled
organisms (jellyfish)
Other eras: started off with little diversity and simple organisms and
became increasingly complex and diverse including large number of
species and the most complex organisms.
Q. What 3 items help us compare animals to their ancestors or to
living organisms today?
A. DNA, Teeth, Bone Structure.
Q. These are the ancestors of a horse. What can you identify in this
picture?
A. I can identify a change in organisms over time
I can

mass
extinctions

of life based

Q. What Evidence do we have that splits the Mesozoic and
Cenozoic?
A. K-T boundary
Q. What was the largest mass extinction in Earth’s history?
Permian- Triassic
. What is the definition of mass extinction?
A.
The extinction of a large number of species
within a relatively short period of geological time,
thought to be due to factors such as a
catastrophic global event or widespread
environmental change that occurs too rapidly for
most species to adapt.

Additional Questions/Notes
Completed “All in the Family activity”
Other than comparing anatomy we can compare DNA, fossils from
ancient organisms.
Q. What piece of evidence did we use to say that hippos and
whales were the closest living relatives to each other?
A. DNA
Q. How can we compare these two organisms?
A. Bone Structure.
I can collect
data to use
as evidence
when writing
a scientific
explanation
showing the
relationship
between
whales and
ancient
mammals.
Mesonychids
Cetaceans
Perissodactyl
Artiodactyl
Ungulate
Q.
What does these organisms bone structure say about these
animals?
A. they all have a common ancestor.
I can use
evidence to
develop a
scientific
explanation
showing the
relationship
between
whales and
ancient
mammals.
I can analyze
pictorial data
to sequence
developing
embryos
from early,
middle, and
late stages of
development
.
Q. How can we compare Mesonychids with modern day
whales?
A. Their Primitive whale teeth.

Species
Vertebrate
What Similarities do the stage 1 embryos have?
A. Similarities include similar eyes, tails and
visible spinal cords.
Q. What does the first Stage tell us about a calf, Human, fish,
and a pig?
A. Common Ancestors
Q. Odd one out
Fish/14
Q. What difference do stage 3 pigs and
chickens have?
Snout and beak, a chicken has wings and a pig would have 4 legs.
Q. Describe a trend you observed as the embryos developed
from stage to stage.
A) The Embryos become more developed as you go from
stage to stage.
