speciation
evolution
fitness
Which are causes of speciation? Choose all that apply
Isolation caused by mountains, rivers and man-made structures
preference for different foods
change in environment

Which of the following lines of evidence shows that whales are descended from a land-dwelling, four-legged ancestor?
Whales have bone structures in their forelimbs and pelvis that are similar to those of terrestrial mammals
Whale embyros have similar structure to embryos of land-dwelling mammals, birds, and reptiles.
An analysis of DNA shows that whales' closest living relatives are hippopotamuses.
A, B, and C
Which of the following is required for a population to diverge into two separate species?
The two populations must have evolved different physical appearances.
The two populations must have mutated at least 10 times.
The two populations must have become reproductively isolated.
The two populations must have evolved analogous structures.
Extantion
Elimination
Extinction
Gene Flow
isolation from parent population
A single species speciates into several species that become more and more different over time is an example of....
When two totally unrelated species are shaped by the SAME environment in such a a way that they begin to resemble each other, this is an example of....
This is an example of....
symmetric evolution
Which of the following statements accurately describes the role of mutations in evolution?
Mutations are the raw material for natural selection, but most mutations do not result in evolution.
Most mutations result in a species becoming more dangerous or aggressive.
An organism can decide to mutate if the environment makes a mutation necessary for survival.
Mutations are almost always beneficial for an individual.
The palmarus longus tendon, pictured here, no longer serves a purpose in humans, but provides evidence of our species descendance from tree-dwelling ancestors. The palmarus longus tendon is an example of:
a vestigial structure
a homologous structure
bipedalism
convergent evolution
