Patterns of Evolution

Key Terms Natural Selection Artificial Selection Convergent evolution Divergent evolution Co-evolution

Artificial selection is intentional breeding for certain traits or combination of traits. A.True B.False

The process of natural selection can happen to any species. A.True B.False

Natural selection operates only on populations, not individuals, over generations. A.True B.False C. All of the above

Convergent evolution Similar traits develop in organisms who do NOT have a close ancestor Traits are due to adaptations to similar environments

Divergent Evolution A pattern in which highly distinct (very different) species were once similar to an ancestral species Ancestor = organism from the past

What is an example of divergent evolution? A.Black squirrels B.Homo Sapiens C.Finches on Galapagos Islands D.A Liger

Divergent evolution is the same as convergent evolution. A.True B. False

What is the process in which species that are NOT closely related to each other independently evolve SIMILAR kinds of traits? A.Natural Selection B.Convergent Evolution C.Divergent Evolution D.Co-evolution

Co-evolution A process in which the changes in the genes of one population bring about changes in a different population The organisms involved share a symbiotic relationship

What is NOT one of the three types of species that offer the most fertile ground for co-evolution? A.Predators B.Prey C.Scavengers D.Parasites
