- 1What is sexual selection?-Preferential survival of features and/or behaviors that maximize the chances of reproduction.
- 2What is genetic drift?-Neutral evolution
-Changes in gene frequencies due to random or circumstantial changes.
(Prob. the #1 most important evolution process)
Ex. African and Indian rhino horn amounts
Ex. Viruses - 3What is lateral gene transfer?-Transfer of genes between organisms by means other than reproduction.
-Common in bacteria
Ex. (Bacteria genes common in bean beetle) - 4☼ What is heterochrony? ☼Hetero = different; Chrony = time
