Million Years Ago 000 Years Ago
951 wordsEvolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten different types...

Homo Habits East Africa
308 wordsHomo habits is the earliest known species of the genus. It existed from approximately 2. 2 to 1. 6 million years ago in east Africa. Only a few fossil remains have been discovered so far, but these specimens exhibit a clear trend toward larger brain size. H. habits brains are about 30 % larger than those of A. africanus. Males were much larger than females. A skull found in 1972 on the shores of Lake Turkana, it represents the oldest individual human yet found. The kind of environment in which t...

Biological And Cultural Adaptive Radiation Erectus
457 wordsAbout one million years ago, Homo erectus populations began migrating out of East Africa. They soon spread into South and West Africa, Asia and Europe. This adaptive radiation was the result of several biological and cultural factors. H. erectus was physically larger than earlier hominids. This probably allowed them to fun faster and further than their ancestors and could have given them an advantage in hunting and escaping. It may also have increased their food gathering abilities by expanding ...

Cranial Capacity Significant Differences
983 wordsThe Human Brain Through the use of molecular biology it is thought that the hominidae family first appeared about 5 million years ago. Based on this time frame it is believed that an African Hominoid lineage was present shortly before that time, approximately 10 my, which contained the common ancestor to both the chimpanzee and human. The split into proto-chimpanzee and proto-human occurred during the last million years of the Miocene epoch. (Changeux and Chavaillon pg. 61). The fossils, especia...

Million Years Ago 000 Years Ago
1,149 wordsOur Human Evolution Human Evolution Our farthest believed ancestor is believed to be Australopithecus afarensis. This species, which lived between three and four million years ago, is believed to be the first real hominid because it is the oldest, and most primitive of any definite hominid form thus far found. Evidence from fossilized footprints, as well as pelvic and leg bones, which were similar to modern hominids, led scientists to believe that they could walk upright. Its teeth resembled mor...
