Evolution - Natural Selection & Mechanisms

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

Bats are common in Texas, especially in rocky regions. Bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting.

Which of the following is a term for a group of similar organisms that can reproduce fertile offspring?

• individual
• population
• species
• fossil

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population
