Document Summary
Microevolution: a subfield of evolutionary studies that devotes attention to short-term evolutionary changes that occur within a given species over relatively few generations of ecological time. Between 1930-40s, biologists and geneticists worked to combine darwinian (natural selection) and mendelian (heredity) theories. Neo-darwinism had challenged the 19th century anthropological concept of biological race . Post wwii, anthropologists rejected race-based physical anthropology, replacing it with modern biological anthropology. Research in biological anthropology was built on humans all being members of the same species, and then address their differences through theories of neo-darwinism o o. Species: a distinct segment of an evolutionary lineage: different biologists who work with living and fossil organisms, have devised different criteria to identify boundaries between species o. Biological species concept: a reproductive community of populations that occupies a specific niche in nature (mayr 1982, 273) This has been very useful for biologists studying populations of living organisms, however it is not useful for studying fossils.
