ANTHR 101 Lecture Notes - Lecture 8: Speciation, Reproductive Isolation, Carl Linnaeus
Document Summary
Hardy-weinberg principle no evolution will occur in a population that: Has no mutation no new materialism is added to the population. If one of these is broke then there will be a change in allele frequencies- evolution is occurring in that population. Interbreeding populations reproductively isolated from other such populations. Evolutionary lineages with their own unique identity. Species based on the uniqueness of their ecological niche. Species based on unique traits or behaviors that allow members of one species. Recognition species concept to identify each other for mating. Help us answer that two organisms aren"t two same species. Analogous structures: structure in different organisms that are similar in function but do not due to a common ancestor. Homoplasy- process that leads to the development. Structures that are shared by species on the basis of descent from a common ancestor but do not necessarily have the same function.
