Natural selection is when organisms that are better suited to the environment survive longer. Mutation is when a genes structure changes. Mutations almost always affect organisms negatively. Sexual selection is when one sex of a species selects another as its mate due to its characteristics. Genetic drift is when certain traits disappear when the organisms with them die or do not reproduce. The bottleneck effect is when a species goes through an event that lowers its population significantly. Founder effect is when the genetic diversity is reduced due to a small starting population. Homologous structures are structures that are similar in different organisms because they descended from a common ancestor. Vestigial organs are organs that have no real purpose because only the ancestor of the organism had a use for them. Ontogeny recapitulates phylogeny is the hypothesis that the embryo of an animal goes through stages that resemble adult stages of the animals ancestors. Molecular evolution is when the composition of cellular molecules like DNA, RNA, or proteins change.]]> 2021-05-22 18:13:50 UTC https://padlet.com/richardblaine/t47xbv0w4f1z131t/wish/1550353639 richardblaine https://padlet.com/richardblaine/t47xbv0w4f1z131t/wish/1550448456 2021-05-22 19:50:03 UTC https://padlet.com/richardblaine/t47xbv0w4f1z131t/wish/1550448456 richardblaine https://padlet.com/richardblaine/t47xbv0w4f1z131t/wish/1550448934 I learned that human ancestors used tools to gather food and scrape things.
