History of our evolution
- An increase in brain size
- A decrease in teeth and jaw size
- The development of technology
- The development of language and culture
population has now produced the modern chimp
- Those that adapted to open and dry habitats. This population has
now given rise to humans (genus=homo)
bipedalism developed (4-6mya) and this could possibly have been
due to the more open environments
-Around 2 million years ago, Homo erectus migrated out of Africa and populated the Old World
-Around 200,000 years ago, the modern Homo sapiens migrated from Africa and eventually populated the world
- All living primates of today diverged from a common ancestor between 65 and 85 million years ago, however, the hominid line of species diverged from the African ape line around 8 million year ago. From this stage, many adaptions and developments occurred within the hominid line but modern humans are what remains of the hominid line. Such developments include:
- An increase in brain size
- A decrease in teeth and jaw size
- The development of technology
- The development of language and culture
- Around 8 million years ago, the hominid sub-family within Africa was split into two populations by the occurrence of a dramatic change in climate. The two populations that resulted were:
population has now produced the modern chimp
- Those that adapted to open and dry habitats. This population has
now given rise to humans (genus=homo)
- The surmised view of hominid evolution outlines the following patterns:
bipedalism developed (4-6mya) and this could possibly have been
due to the more open environments
-Around 2 million years ago, Homo erectus migrated out of Africa and populated the Old World
-Around 200,000 years ago, the modern Homo sapiens migrated from Africa and eventually populated the world
- The large geographical expansion of the genus Homo across the world links to the idea that the genus Homo originated from Africa
