Evolution Stages Of Hominids

1.There are two main theories about the creation of humans we are going to talk about.


2.The first one is Adan & Eve's which is the religious one from the point of view of the Christians. This theory explains that god created the first human (Adan) and then from his rib he created Eve. They lived in heaven.


3.The other theory we would like to talk about is the scientific one. This explains that at the begining we all were bacterias and how we went evoluting until we reached what we are now.


4.So why have we evolved? In each generation, the structure of our DNA changes because we adapt to environment. For example, the monkey suffered some changes because of its moment's nature and then Australopithecus appeared.


5.Darwin's theory (the natural selection) explains that the strongest species survive, this means that the specie that adapts the best to its moment's environment is more likely to survive. 
We suffer genetic mutations, which are adantages, and these are inherited by our descendants. This is why we change or mutate.


6.The first Australopithecus appeared in Ethiopia. First they expanded all over Africa and then moved to Asia, Europe


7.Lucy was the first hominid that was found by us, humans. It was found in Ethiopia (Africa). It is an early female australopithecus, and it is about 3.2 million years old. We don't have her full skeleton kept, we have its %40. She was bipedal.


8.The main differences between the first hominids and us (humans) are...
We now:
  -have  a bigger brain
  -walk in an upright position
  -don't use hands to walk
  -have  a smaller jaw


9.Australopithecus Afarensis.
  They lived for 1 million years, and during that period they didn't suffer any changes or mutations. However, when that period ended they suffered a change, which made this type of hominid mutate and become another hominid. The Australopithecus changed because of the cold climate, which decrease their standard of living.


10.Homo Habilis.

12.Homo Erectus.
  This hominid is well-known because it was the first hominid to walk in an upright position. It also improved the tools that the Homo Habilis used (their previous generation).


13.Homo Neanderthalensis.
  They lived in Europe 200,000 years ago. They were smaller than Homo Sapiens. They had large nasal cavities and skulls.


14.They lived in groups, in small villages. They built houses, which were usually made of bones, but they could also be built of wood. They buried their dead relatives.


15.They are famous because they were the first hominids that started to paint, inside of caves. They started to paint people, but later they changed the theme to animals they hunted, such as bisons.


16.They used caves as canvas, hands as paintbrushes and some materials (animals' blood, coal, animals' fat/grease...) as paint.

20.The language is claimed to be the biggest problem in science. Scientists know that they communicated making weird sounds, but they don't know which hominid was the first one to creat an official language yet.
