A history of the human evolution

A jawbone found in Ledi-Geraru, also in the Afar — marks the debut of Homo in the fossil record at 2. Nevertheless, many people have come to reconcile their beliefs with the scientific evidence.

Since that time, human evolution has been primarily cultural as opposed to biological. The idea of a missing link has persisted, but it is not actually a scientific term. Homo erectus was also spawning lineages that definitely did traipse into Western Europe, and others that would go on to become the globetrotting modern humans.

Australopithecines An African apelike species evolved probably around 6 million years ago with two skeletal characteristics that set it apart from apes: small canine teeth the teeth on either side of the four front teeth compared to the long canines found in almost all other primates, and, most importantly, bipedalism or walking on two legs as the primary mode of locomotion.

Recent studies suggest that Australopithecines still lived part of the time in trees as a result of maintaining a grasping big toe. Although stone tools dating back to 3. Usually, the remains were buried and preserved naturally.

As they moved out of Africa they very soon replaced the variety of other Homo geneses roaming the world Ingold abc. Then two species broke off into separate lineages, one ultimately evolving into gorillas and chimps, the other evolving into early humans called hominids. Another change is the shape of the big toe.

However recent fossil findings by the paleoanthropologist have revealed that Australopithecus, Homo habilis, and Homo erectus lived in different parts of the world at the same time Walker ; Kesol ; Leakey Their descendants then later migrated to other regions.

In fact, the fossil record does not represent a straight line of ancestry at all; many of these early hominids left no descendents and simply died out.
