Document Summary
1. 4: evolution explains the diversity as well as the unity of life. Evolution: change in the genetic makeup of biological population through time. Natural selection: the differing survival and reproduction among individuals in a population due to adaptations. Proximate explanations considering the immediate genetic, physiological, neurological, and developmental processes that explain how an adaptation works. Ultimate explanations concerns the process that led to the evolution of the trait.

Binomial nomenclature the two names for each species. Hierarchy of life: species genus family orders classes phyla kingdoms. Polyphyletic a taxon that does not include its common ancestor.
