ANT201H5 Lecture Notes - Lecture 2: Trinil, Hand Axe, Unified Atomic Mass Unit
Document Summary
Ice age begins with several hominin species, but as it progresses: fewer hominin species, dispersal from africa occurs, only has genus homo surviving, dispersal single species disperses. Dispersal expansion of populations into new ecological environments: not individual event. Possible due to increased cc and development of refined tool tech (acheulian: not sure in what capacity but it occurred around the same time. Increased cranial capacity: habilis 500-800, erectus 800-1200, neaderthal 1200-1600, sapiens 1200-1500. Smaller teeth foramen magnum forward homo erectus. Hand axes are the first sign of purposeful design + aesthetic + tear drop shape cleaver flake tools variation. England: clactonian industry no hand axes, schoningen site use of wood. East asia: bamboo and wood tools, simple choppers and flake tools. Aid with dispersal: beeches pit site, england 400kya, gesher benot ya"akov, israel, 780kya. Berekhat ram site: volcanic rock with incision. Sima de los huesos (atapuerca, spain: 27 individuals in crevice.
