Body parts that function like each other, but are different in structure.

• embryos
• homologous structures

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• artificial selection
• inbreeding
• outbreeding

Genetic drift is change in the allele frequency of a population due to...

• random chance

• natural selection

• non-random mating (sexual selection)

• artificial selection

This mechanism of evolution occurs when populations migrate.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

One day a group of scientists collected a small group of brown anole lizards from a large group of the lizards.  Then they placed this small group of lizards on an island that had no brown anole lizards on it.  What is this an example of?
