• rapidly buried under sediments

• eaten by scavengers

• reincarnated

Individuals that are better able to cope with the challenges of their environment tend to  

• Decrease in population over time.
• Leave more offspring than those less suited to the environment.
• Leave fewer offspring than those less suited to the environment.

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

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.

• Genetic Drift
• Natural Selection
• Non-random mating
• Mutation

Charles Darwin observed that finches of different species on the Galápagos Islands have many similar physical characteristics, this supports the hypothesis that these finches

• are twins

• acquired traits through use and disuse.

• all eat the same type of food.

• descended from a common ancestor.

Modern whales developed their traits through natural selection.  What occurs during the process of natural selection?

• Organisms choose mates from other species to create new species
• Breeders selectively cross organisms with desired traits
• Only the fittest organisms can survive and reproduce
• Organisms remain exactly the same over time.
