2024 U9 Evolution Unit Review

Different organisms having the same bone structures indicates

• analogous structures; same function

• homologous structures; same function

• homologous structures; different function

• analogous structures; different functions

Slow, increased fitness, environmental pressures go with?

• artificial selection

• extinctions

• farming

• natural selection

Which structures would support ancestry/common ancestors?

• analogous

• homologous

• vestigial

• convergence

If the DNA sequence is the same for a gene in different organisms, this means the organisms will

• be the same

• produce the same protein

• have the same body structures

• produce the same tissues

Homologous structures indicate what type of evolutionary change?

• gene flow

• genetic drift

• convergent evolution

• divergent evolution

If a population is NOT undergoing evolution, that means it is

• in osmoregulation

• in homeostasis

• in genetic equilibrium

• in extinct

This image is an example of

• stabilizing selection

• disruptive selection

• artificial selection

• directional selection

This image demonstrates

• stabilizing selection

• artificial selection

• disruptive selection

• directional selection

The structures in this picture are

• homologous

• analogous

• vestigial

• compound

The theory that says some organelles of eukaryotic cells evolved from prokaryotic cells is called

• natural selection theory

• punctuated equilibrium theory

• speciation theory

• endosymbiotic theory
