Evolution Unit Review

All of the genetic information found in a population.

• population

• genetic drift

• evolution

• gene pool

Bats are common in Texas, especially in rocky regions. Bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting. This adaptation is becoming more frequent in the population. What mechanism of evolution is this?

• Natural Selection

• Non-random mating

• Gene Flow

• Genetic Drift

Analogous structures show common ancestry.

• True
• False

• Homologous
• Vesitigial
• Analogous

If an organism has a vestigial structure, that structure likely once had a function in a(n)

• close relative
• early ancestor
• unrelated organism
• embryological stage

The hind leg bones in a whale are examples of

• homologous structures
• analogous structures
• fossils
• vestigal structures

How would you describe this evolution?

• Homologous structure
• Analogous structure
• Structural adaption
• Functional adaption

Evolution occurring gradually and slowly over long periods of time

• Homeostasis

• Stasis

• Punctuated Equilibrium

• Gradualism

What type of evolution where there is a sudden, rapid change then no change for a long time?

• Co-Evolution
• Punctuated Equilibrium
• Divergent Evolution
• Convergent Evolution
