Use the following information to help you answer questions 13-15.
The horse family has a detailed evolutionary history in the fossil record. Some of the many fossil horses
that have been found include miohippus (MIO), hipparian (HIP), and equus (EQU)(the modern horse). Look
at the rock layers shown, and use that information to answer some questions about the horse fossils.
14. a. Which horse evolved first (lived the longest ago)?
b. Which horse lived most recently?
15. Give the approximate date range for
when each of the horses lived (in millions of
years ago).
a. MIO
b.
HIP
c.
EQU
16. Imagine a horse that is descended from
MIO and is a common ancestor of both HIP
and EQU. In which rock layers would you look
for a fossil of this animal?
a. Mark with an arrow where you think you
would find the fossils on the rock layer
diagram.
b.
Then explain below WHY you think you
would find this fossil there.
The earliest horses are thought to have lived in damp forests with very soft ground, and ate brush, much
like deer do today. They had several toes on each foot, and were only a few feet tall. Later, horses lived in
dry grassland climates where the ground was very hard. Over time, horses became much taller and
developed hooves on their feet, and became grazers.

17. How would a scientist explain how horses changed from being small and having toes, to being
tall and having hooves? Give a detailed explanation. Use the following words in your answer:
natural selection, adaptation, selective pressure, and variation.

22. Read the following statement. Use what you have learned about natural selection and evolution to
explain why you think the statement is an accurate or inaccurate description of how species change
across time. Be sure to include all applicable vocabulary in your explanation for what is happening in
this scenario
“Elephants wanted longer trunks for reaching leaves, so they stretched and stretched their trunks
until they got longer. They then passed on the longer trunks to their offspring.”

23. Examine the sample cladogram, each letter on the diagram points to a derived character, or
something different (or newer) than what was seen in previous groups. Match the letter to its
character. Note: this cladogram was created for simplicity and understanding, it does not
represent the established phylogeny for insects and their relatives.
