Document Summary
Basic characteristics for living things: take in energy and materials from environment , sense and respond to stimuli, reproduce and grow, consist of one or more cell, maintain homeostasis, undergo evolution. Kingdoms: anamalia, plantae, fungi, protists (all part of eukarya domain: share a similar body organization (membrane bound nucleus, all adapted for niches and life styles, domains archaea and bacteria have a lack of membrane bound nucleus. Descent through modification, development of body structures, change through time. Taxonomy: is concerned with identifying, naming and classifying organisms: broken down into kingdom, phylum, class, order, family, genus, species, humans fall into the respective categories; kingdom: anamalia, phylum: vertebrata, class: mammalia, order: primates, family: hominidae, genus: homo, Species: sapiens: with other organisms things are always changing, taxonomy reflects relatedness . Speciation: the formation of new species (humans did not evolve from apes, but rather they share a common ancestor. Two general modes of speciation are distinguished by the mechanism by which.
