Why do scientists think that human population started in africa? and dont post if you got a simple answer..

The DNA evidence is based on mitochondrial DNA (please research so you understand). 2. What evidence do you have that non-caucasian Ethnicities have weaker immune systems? I believe you are misinformed.3. You misunderstand evolution in concept; we are not necessarily all evolving to become more intelligent & stronger.......

you say only highly intelligent people are allowed to answer, but you spelled half your words wrong and your grammar is atrocious.

1. You forget paleontology & radio carbon dating. Also, all of the early human ancestors (homo erectus etc) come from Africa. The DNA evidence is based on mitochondrial DNA (please research so you understand).
2. What evidence do you have that non-caucasian Ethnicities have weaker immune systems? I believe you are misinformed.
3. You misunderstand evolution in concept; we are not necessarily all evolving to become more intelligent & stronger. Rather what makes you evolutionarily successful is how many of your offspring survive, how many you have, and how well they reproduce in turn etc. Being intelligent and/or strong does not always equate to having a large & successful family tree. Hence the wide range in intelligence, size, colour, strength etc in the human race and other species of animals etc.
4. Actually if you have a group of black people living isolated in somewhere in Russia for about 24,000 years they would become white as skin colour strongly affects the effects of sunlight on the skin (long story short the whiter your skin the easier you find it to absorb vitamin D but also the easier it is to get sun-burnt, while as dark skin doesn't absorb vitamin D as easily but also does not burn as easily either, hence darker skinned races being predominant in very sunny parts of the world and fairer skinned races in less sunny parts of the world etc. There are problems surrounding both Vitamin D deficiency & sun burn).

Really the only one here who is making a fool of themselves is you. Just because you do not understand something does not mean that it is not right or logical in concept. You have a lot more learning to do before you have any ground to stand on to not foolishly make your assumptions. It is obvious that you are very misinformed/fundamentally uninformed on some of the matters you speak of.
