carbon-14 courting
- uses the decay of carbon to n in organisms.
- charcoal quality fabric to this point.
- most effective beneficial for sites as old as around 50,000 years.
potassium-argon (ok/ar) relationship
- can date volcanic rock. k decays to ar.
- beneficial again to four.5 billion years (1/2-existence 1.three b.y.).

Document Summary
Uses the decay of carbon to n in organisms. Most effective beneficial for sites as old as around 50,000 years. potassium-argon (ok/ar) relationship. Can date volcanic rock. k decays to ar. 2-1-2-three while do human everlasting molars erupt? first molar erupts @ 6yo. ***strepsirhines have postorbital bar. postorbital closure whole encasing of eye by using bone. Inhabit indonesia, philippines platyrrhines new global monkeys tendencies of old world monkeys. Typically occur in family gadgets, complex social business enterprise (multi-male, multi-female) Calluses on rump (ischial callosities) contributors of the superfamily hominoidea gibbons, orangutans, chimps, gorillas, humans trends of hominoidea. A few especially arboreal (gibbons, orangs, chimps), others terrestrial (gorillas) Face is naked, facial expressions play essential role in social interactions. Specifically vegetarians participants of circle of relatives hylobadtidae gibbons and siamangs traits of hylobadtidae. Low sexual dimorphism members of family pongidae orangutans, gorillas, chimpanzees, and bonobos traits of orangutans. More solitary and greater arboreal than other apes.
