This is an ecological relationship in which two or more organisms depend on the same limited resource.

What did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

• different species on different islands

• all species on one of the islands

• identical species on all the islands

• the same species as North America

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

Natural selection results in change over time by acting on traits that are

• heritable
• new
• mutated 
• better than the best

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures
