Which of the following describes natural selection?

• it acts on genetic material directly

• it acts on existing physical traits

• it forms new traits

• it forms new genetic material

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

The more genetic variation a population has,

the more likely it is for some individuals to

• evolve

• migrate

• survive

• mutate

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• mutation
• gene flow
• gene pool
• allele

What increases genetic variation when animals move  from one population to another

• genetic drift
• sexual selection
• bottleneck effect
• gene flow

The five-factors for evolution are gene flow, genetic drift, mutation, natural selection and ....

• non-random mating

• controlled mating

• emigration

• immigration

What is speciation?

• combining of tow species to form one with different traits
• isolation that affects mating behaviors
• timing of mating that prevents normal sexual selection
• divergence of two or more species from an existing one

NGSS.MS-LS4-4

two species are in different environments and look very similar.  However, that are not closely related (analogous).  Their resemblance is most likely an example of.

• sexual selection
• temporal isolation
• convergent evolution
• divergent evolution

NGSS.HS-LS4-4

What is the term for a feature that allows an organism to survive better in its environment?

• variation

• adaptation

• homologous structure

• vestigial structure
