Lesson Summary: Interview: Douglas Futuyma on natural selection

Lesson summary for... Interview: Douglas Futuyma on natural selection Author/Source: ActionBioscience.org

Overview:	This interview with one of the most influential evolutionary biologists of today addresses many aspects of natural selection: how it works, examples, misconceptions, and implications. This article appears at ActionBioscience.org.
Concepts:	This lesson covers the following concepts: Evolution results from selection acting upon genetic variation within a population. New heritable traits can result from recombinations of existing genes or from genetic mutations in reproductive cells. Mutations are random, but selection is not; selection is dependent on many factors. Traits that are advantageous often persist in a population. Natural selection acts on individuals and populations in a nonrandom way. Organisms cannot purposely produce adaptive mutations in response to environmental influences. Evolution may occur as a result of genetic drift. Speciation is the splitting of one ancestral lineage into two or more descendant lineages. Evolution does not consist of progress in a particular direction.
