Document Summary
Chapter 4- what can evolutionary theory tell us about human. Evolutionary studies can be divided into 2 major subfields: 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. Measured in geological time, spanning many generations of organisms along with the development and decay of many different ecological settings. In 30s and 40s, worked to formulate a new way of thinking about evolution that combined darwinian natural selection and mendelian ideas about heredity (called modern evolutionary synthesis or neo-darwinism) Microevolution- short-term evolutionary changes within a given species and within a short period of ecological time (short-term, experienced by that species) Many taxonomists working with living primates prefer to use the phylogenetic species concept identifies species on the basis of a set of a unique features. Contemporary paleoanthropologists sometimes apply a phonetic fossil species concept.
