camouflage
________ is when an organism has the best traits that allow it to survive, reproduce and pass the traits onto offspring.
natural selection
evolution
artificial selection
camouflage
A beneficial structure or behavior which causes a species to become better suited to its environment is called a (n) ________
adaptation
comparative anatomy
vestigial
none of these are correct
Your arm and a bat wing is an example of a(n) _______structure, similar structure, different function.
analogous
homologous
vestigial
gene pool
A change in DNA caused by radiation, chemicals, or randomly, is called a _____.
mutation
adaptiation
natural selection
diversity

Adaptation
Mutation

mutation
natural selection
competition
comparative anatomy

adaptive radiation/
divergent evolution
convergent evolution
genetic drift
gene pool

Changes in species occur due to
mutations
changes to the habitat
both answers are correct
neither answers are correct
