Evolution Quiz Review – Revision Notes & Practice Guide
What are fossils? - ANS ✔✔the preserved remains or traces of organisms that lived in the past
Where are older fossils found? - ANS ✔✔bottom layers
Where are newer fossils found? - ANS ✔✔near the surface of the earth
What clues about an organism are found in fossils? - ANS ✔✔how the organism lived and
looked
What is meant by "holes" in the fossil record? - ANS ✔✔there's not a fossil to show that 2
species are related
How did Darwin describe evolution? - ANS ✔✔descent with modification
How does the fossil record support Darwin's theory? - ANS ✔✔As modern horses descended
from ancient horses, they changed
What are analogous structures? - ANS ✔✔2 structures that aren't related, but have a similar
purpose
Do organisms with analogous structures share a common ancestor? - ANS ✔✔No
Why do the organisms look so similar? - ANS ✔✔they evolved to adapt to a specific
environment
, How are a bat wing and a butterfly wing similar? - ANS ✔✔both of their wings are used to fly
How are a bat wing and butterfly wing different? - ANS ✔✔bat wings have bones, but butterflies
don't
What is convergent evolution? - ANS ✔✔when unrelated organisms evolve similar features,
structures, or adaptations
Why does a masosaur, shark, and dolphin look similar? - ANS ✔✔- all live in water
- stream lined bodies help them move through the water
What are vestigial structures? - ANS ✔✔body parts that have reduced or not fully developed
their structure
Why would organisms have structures that are vestigial? - ANS ✔✔organs that used to perform
an important function in the past
What do the hind limbs of whales most likely reveal about their ancestors? - ANS ✔✔their
ancestors walked on land
What are homologous structures? - ANS ✔✔body parts that have similar structures, but
different uses
What is meant by "divergent evolution" in the case of the forelimbs of vertebrates? - ANS
✔✔when organisms with shared traits turn into different variations over time
From what did they diverge? - ANS ✔✔common ancestor
