ANT 101 Lecture Notes - Lecture 24: Evolutionary Anthropology, Biological Specificity, Macroevolution
Document Summary
Macroevolution: refers to large-scale changes at or above the species level, extending over a geologic area, and resulting in the formation of new taxonomic groups. Speciation encompasses the various evolutionary processes that result in a new species. Typological definition: a single, distinct class of living creature with features that distinguish it from other species (refer to ch 1) Modified: individuals are the same species if they can successfully produce fertile offspring. At least 12 modern definitions of species but 2 have the strongest mate and produce a fertile hybrid relevance to evolutionary anthropology: biological and phylogenetic species concept. Results from the work of 20th century geneticists and other researcher who study the diversity of life on earth. Researchers noted that any one feature rarely defines a species, since many species share similar features from common descent. Ernst mayr (1942) defined biological species as actually or potentially interbreeding populations, which are reproductively isolated from other such groups.
