Is the theory still true that humans originated in Africa?

Most mammals have light skin that is covered by fur, and biologists believe that early human ancestors started out this way also. Dark skin probably evolved after humans lost their body fur, because the naked skin was vulnerable to the strong UV radiation as explained in the Out of Africa hypothesis. Humanity literally wouldn't exist without white skinned Africans. Black people pathetically try to claim the first African (Lucy) was a black woman when she was actually Australopithecus Afarensis. A species that existed LONG before black people or any homo-sapiens existed. black people have up to 19% genomic contribution from unidentified archaic hominids making them less human than non-blacks. It's easier for blacks to believe in lies than to actually do research. 

Yes. The closest relatives of humans (chimps and gorillas) are in Africa, the place with the most genetic diversity in the world is Africa, DNA evidence places our origins in Africa, and the oldest fossils of ancient humans were found in Africa.  There is no competing theory that has anywhere near this much evidence. 

Yes. Both fossil and DNA evidence suggest that Homo sapiens and our other earlier ancestors evolved in Africa.The oldest known fossils of H. sapiens is found in Africa and dated to about 200,000 years old. DNA evidence suggests that the earliest branches of human evolution also originated in Africa. All non-Africans evolved from a small group of Africans who migrated out of Africa about 60,000 years ago.  The oldest human fossils found outside of Africa are found in Australia and they are dated to about 40,000 years ago.  Scientists suggest that humans migrated out of Afica along the coast line from east Africa, past the Middle East and they then went to SE Asia before moving into Australia (probably by boat) from Indonesia. The fossil and archaeological evidence of this coastal route were then inundated by rising sea levels when the ice age ended 13,000 years ago.  Subsequent human migrations from Europe and north Asia nearly covered up the evidence of this early migration as well. It took some work to find a person who is related to the Australian aboirigine in a small village in South India. He looks African, with curly hair and dark skin while most of the people in his village look more like Caucasians. 

Homo Sapiens yes. AFAIK no new findings have predated Jebel Irhoud.

yes          

Yes. As current estimates on The male most recent common ancestor ("Y-chromosomal Adam" or Y-MRCA) converge with estimates for the age of anatomically modern humans and well predate the Out of Africa migration, geographical origin hypotheses continue to be limited to the African continent.
