The general lineage species concept - ANSWER-is the idea that species are metapopulations of organisms that exchange alleles frequently enough that they comprise the same gene pool and therefore the same evolutionary lineage. speciation - ANSWER-is the evolutionary process by which new species arise. Speciation causes one evolutionary lineage to split into two or more lineages (cladogenesis). An isolating barrier - ANSWER-refers to an aspect of the environment, genetics, behavior, physio...

Evolution notes discussing the 3 main species definitions, and models of speciation, including visual aids. Discusses mechanisms of speciation including pre and post zygotic barriers, and genetic drift.

BIOL 3040 STUDY GUIDE II, PART A Chapter 4 Synapomorphy: A character or trait that is shared by two or more taxonomic groups and is derived through evolution by a common ancestor. Homoplasy: Correspondence between parts or organs acquired as a result of parallel evolution or convergence. Homoplasy is analogous and can be due to convergent evolution 1. According to the tree below: a Species B is more closely related to species G than species A b Species B is equally related to specie...
