The oldest known specimen is "Lucy" a 3.2 million year-oldpartial skeleton found in November 1974 at Hadar, Ethiopia (Kreger, 1). However, it has also been suggested that Homo neandertalensiswere subsumed into the various populations of Homo sapiens (Origins ofHumankind, 2, 1). Australopithecus afarensis had a very low forehead, a face thatprojected forward and a prominent brow ridge. Homo neanderthalensis are believed to have been strong by modernstandards and able to adapt to substantial climate variations. Available at www.pbs.org/wgbh/evolution/humans /humankind/n.html. Johanson and T.White in 1978. Works CitedKreger, G. Itpossessed a protruding jaw, receding forehead, and weak chin and had abrain slightly larger than modern humans (Origins of Humankind, 2, 1).They lived mostly in cold climates, roaming the earth with Homo sapiens.Fossil evidence has been found for this species in many differentlocations, including Europe and the Middle East, suggesting a multi-regional range (Origins of Humankind, 2, 1). Its brain was about one-third the size of the average modern human brain. Presented below is a chart depicting the relationship ofthese species. 1. David. "Australopithecus Afarensis." 2 8. Any numberof researchers working in Belgium, Iraq, and France have identified fossilssupporting the thesis that Homo neanderthalensis roamed widely acrossEurope and the Middle East before being driven to extinction by Homosapiens. The knee and pelvic bone of this species were humanlike leaving nodoubt that they walked upright and possessed an anatomically modern humanknee (Origins of Humankind, 1, 1). 1) Three major hypotheses for the origins of Anatomically Modern Humansare: 1) Homo sapiens left Africa between 1 , and 5 , years ago insearch of more space and newer habitats; 2) Homo sapiens were betteradapted and quicker witted than Homo neanderthalensis; and 3) Homoneanderthalensis were subsumed within various populations of Homo sapiensthat left Africa at different times.
