- Erectus
A religious theory about all living things created by Divine power.
scientific name for modern humans
Scientific theory about the origin of all living things.
Walk on two rear limbs or Legs.
Up right human beings.
3.1 The emergence of Human beings
There are two major opposing theories on the origin of human beings. These are the Creationist and Evolutionist (scientific) theories.
3.1.1. The Creationist View
The creationist view :-Advocates that man, including all living things, was created by God or a supernatural being and also have relation with religion.
3.1.2. The Scientific Theory
The scientific theory explains that all living things, including humans, result from a gradual succession process. This slow and natural process is called evolution. Thus this theory is called evolutionist. This theory was formulated by the English scientist Charles Darwin (1809-1882) According to evolutionist theory, all human beings belong to the species Homo sapiens. which descended from a common ancestor or a Genus known as Homo. Humans belong to the Hominid what is known as bipedal, i.e., walking on two feet with an upright position. The earliest hominid to be found in Ethiopia was discovered at Aramis in Afar. It is described by a team of Paleontologists led by Tim White, and it is dated to around 4.4 million years ago. Finally, in 1974, Donald Johansson found the oldest complete human skeleton in Ethiopia named Lucy/ Dinkenash.

3.2 Genus Homo
The three different species that belong to the genus Homo are: Homo Habilis, Homo erects, Homo sapience and Modern Human (Homo sapiens sapiens)
3.2.1. Homo Habilis (Handy human)
Homo Habilis- Is the oldest a handy human being
- The fossil found in the Omo valley in Ethiopia.
- They made the first hand axes or the first stone tools.
3.2.2. Homo Erects or (“upright human being”)
- That emerged around 2 million years ago
- First to leave Africa and moved to Europe
- They learned to use fire to keep warm in colder areas.
- Fossils were found in the Omo Basin, Melka-Kunture, Konso–Gardula, and Middle Awash in Ethiopia.
3.2.3. Homo sapience (wise Human beings )
- Homo sapience were wise human beings
- Very similar to modern human beings.
- The species were found in the Awash,, Omo valleys and near Dire Dawah in Ethiopia.
3.2.4. Modern Human
Modern Human (Homo sapiens sapiens) appeared around 100,000 years ago. They are different in many ways from their ancestors.
