• the study of morphological traits

• the branching patterns of evolutionary relationships

• the process of evolution that creates new species

The change in the genetic composition of a population over time due to random mating is called

• the bottleneck effect

• gene flow

• genetic drift

• mutation

In a particular zoo the population of spider monkeys has a higher proportion of individuals with light golden brown fur than spider monkeys in the wild. if the monkeys were recently captured from the wild and if fur color is largely determined by genetics, what evolutionary process is at work?

• the founder effect

• the bottleneck effect

• microevolution

• artificial selection
