Evidence of Evolution Review

Multiple Choice

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years

• Fossils show that some species have gone extinct

• Fossils show how life forms present today are different than those from the past

• Different sedimentary rock layers provide evidence for how the environment has changed over time

Multiple Choice

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures

• analogous structures

• homologous structures

• fossil structures

Multiple Choice

The diagram illustrates an embryonic stage of two organisms.

Which of the following can be determined by observing the embryos shown in the diagram

• The organisms share a common ancestry.

• The organisms belong to the same genus.

• The organisms are native to the same geographic areas.

• The organisms will grow into anatomically similar adults.

Multiple Choice

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this?

• The function of these bones is the same in all animals

• They live in similar environments

• They have a common ancestor

• All organisms resemble humans

Multiple Choice

The best evidence for evolution is

• fossils

• DNA

• homologous structures

• embryology

Multiple Choice

Vestigial structures

• structures that perform a similar function but are not similar in origin

• remnants of once-important structures that have slowly lost all or most of their function

• features found in different organisms that share structural similarities but may have very different functions

• preserved remains of an organism
