1865-Sir John William Dawson of McGill University identifies "shells" of huge foraminiferal protozoans. Known as or "dawn animal," this find is used as an argument against evolution because it shows a relatively "modern" animal early in the fossil record. It will prove, however, to be a geologically young pseudofossil formed by heat and pressure on limestone.

Evolution as the foundation and more recent adaption for the fine detail.

Anatomical Evidence for Bipedalism

H. erectus is thought to be the first migratory Homo species, albeit contentiously. Several theories concerning the dispersal of early humans have been developed. The 'Multiregional' or 'Regional Continuity' hypothesis involves parallel evolution, foumulated on the basis of fossil evidence. The other models, which were formulated on the basis of fossils, archaeology, and genetics, involve an African origin for human evolution, the most well-known among them being the 'Out of Africa' hypothesis. This hypothesis comprises continuous evolution, with individuals originating in Africa and migrating to Europe and Asia. Some variations among the many African origin hypotheses involve gene transfer between lineages, which will not be discussed here.

H. ergaster lived throughout eastern and southern Africa between 1.9 and 1.4 MYA. Fossils attributed to this species sometimes are considered early H. erectus confined to Africa, as H. erectus has been dated as far back as 1.8 MYA. Remains of H. ergaster have been found in Tanzania, Ethiopia, Kenya, and South Africa. The most-complete H. ergaster skeleton was found at Lake Turkana, but, as mentioned previously, whether it is a late H. ergaster or an early H. erectus finding is debated. This fossil is named 'Turkana boy' or 'Nariokotome boy.'

In my opinion, the hypothesis that makes the most sense is the postural feeding hypothesis. This is because according to the fossil records, the early man’s environmental and practical morphology all suggested that early man used to have two feeding postures, terrestrial and arboreal thus serving as the origin for hominid bipedalism. Fossil records also showed that the hominids were mostly bipedal when they fed on fruits that were up in trees in open forests. This was made possible by their effort to reach up into the tree while standing on the ground or by climbing up in the tree to try to balance in the branches and eat the fruits. The balancing in the branches was done while standing on one branch and holding the upper one in a semi-standing up position. The bone structures of the hominids also proved that they had an upright stance since they had shallow ribcages and long straight vertebrae, suggesting an upright posture (Kuliukas, 2002).
