Evolution and Ecology

Which of the following describes a population?

• the wild dogs and cats that live in the city

• four different species of fish living in a pond

• a group of Canadian Geese living in a pond in Ijams

• roses and sun flowers in a garden

Speciation can occur as a result of geographic isolation because _________.

• members of a species can no longer find mates

• populations that live in different environments may be exposed to different selection pressures

• exchange of genes during recombination

• movement of genes within a population because of interbreeding

Which of the following is NOT a density dependent factor?

• Disease

• Predation

• Limited Resources (food, water, etc.)

• Hurricanes

This is when one species is separated by a geographic barrier. Over a long period of time, they will become two different species. This happened to the common ancestor of the chimpanzees and bonobos.

• Convergent speciation

• Divergent speciation (allopatric speciation)

• Lateral speciation

• Parapatric speciation
