Evolution Exam Review

Pelvis and leg bones in a whale support

• Fossil formation

• Evolution

Similar embryos in species supports

• It is all the same species

• adaptations for the same environment in adults

• A common ancestor

When comparing different species amino acids

• the more similar the amino acid sequence, the more related the species are

• the number of amino acids is dependent on the type of species

• it is difficult to tell if species are related because there are more variables of common ancestry than just DNA

The similarities between these appendages suggest that cats and birds

• evolved from a common ancestor

• evolved gradually over a long period of time

• possess the same number of chromosomes

• occupy the same habitat

• The fossils in layer A are older than those in layer C.

• The fossils in layer B are older than those in layer C.

• The fossils in layer A are older than those in layer B.

• The fossils in layer C are older than those in layer A.

The undisturbed upper layers of rocks usually contain fossils of organisms that are

• less complex than those found in lower layers

• more complex than those found in lower layers

• different from any other fossils found in the same layer

• identical to those found in the lower layer

In the diagram below of undisturbed sedimentary rock strata, in which rock layer are the fossils of simple animals generally found?

• B

• A

• E

• D

What is represented in the diagram below?

• use and disuse

• gradualism

• regeneration

• punctuated equilibrium

What is represented in the diagram below?

• use and disuse

• gradualism

• regeneration

• punctuated equilibrium

The diagrams below represent stages in the embryonic development of four organisms.

The similarities in embryonic development shown in the diagrams suggest that these organisms

• are all members of the same species

• have adaptations for the same environment as adults

• may have evolved from a common ancestor

• all undergo external development
