The idea that better adapted organisms survive to pass traits along to offspring is called ___.
Evolution
Natural Selection
Extinction
Artifical Selection
What is the term for a feature that allows an organism to survive better in its environemtn?
variation
adaptation
homologous structure
vestigial structure
Which best describes the relationship between structure and function in organisms. For example, why do herbivores have flat molars?
Herbivores eat plants because they have flat molars; what they eat will dictate whether they inherit flat or pointy teeth.
Herbivores have flat molars because they eat plats; their teeth shape will affect how successful they are and how common that shape is in future populations.

C, D, and E
D and E
B, C, D and E
What is necessary for speciation to occur (and not just natural selection within a population)?
adaptations
reproductive isolation
development of homologous structures
interbreeding
