Our hominoid line, humans, gorillas, chimpanzees and lesser apes, is one among the superfamily Hominoidea.
See the taxonomic table of primates for two comparative classification shcemes.
Between the mid-1930s and mid 1940s geneticists, systematists and palaeontologists collaborated to create a united approach to evolution, the "Modern Synthesis".
Ernst Mayr reduced all the hominid (human ancestor: (see hominid books)) fossil records to three species, A.
Social forces appear to have directed much of the evolution of humanity but we are still subject to natural selection.
Primate taxonomy (see books: phylogeny, taxonomy, systematics) is in a state of flux due to the discoveries made in primate genetics.

erectus (including the Java and Peking hominids - the archetypal Missing Link) and H.sapiens (including Neanderthals and Cro-Magnon) (see the modern taxonomic classification of humans).This formed the foundation of the neo-Darwinian evolutionary theory.Once multicellular organisation became possible as atmospheric oxygen levels rose, the early multicellular organisms rapidly diverged into many adaptive forms.Mass extinction events and an organism's unique adaptations mark the history of evolution, both of which may lead to adaptive radiation.
