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

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
