Well now they are saying the first humans were Asian. One day they will make up their minds
It's not about 'them' making up 'their' minds...new discoveries are made time and time again. I think it's fascinating.
For the moment, the majority of anatomical, archaeological and genetic evidence gives credence to the view that fully modern humans are a relatively recent evolutionary phenomenon. The current best explanation for the beginning of modern humans is the Out of Africa Model that postulates a single, African origin for Homo sapiens.

Scientists have also discovered an older fossil in Europe. Note though that this is a hominid ancestor
This "into Africa" scenario is likely to be controversial. Critics argue that discoveries like Moy?-Sol?'s are more likely to reflect the quality of the fossil records in Africa and Europe than offer clues to the actual origins of hominids.
Jay Kelley, a palaeobiologist at the University of Illinois at Chicago, points out that the fossil record from the time in question is much better in Europe than in Africa. "If you've got a record on one continent but not the other, naturally you're going to see origins of the group from the continent where you've got the record," he says.

Some of the comments on the article are also helpful. Like this one
Africa is the most likely location of the common ancestor. The 500,000 year estimate is based on mitochondrial DNA differences between homo sapiens and homo sapiens neandethalensis. The two species share 99.5% of their respective DNA. The amount of mutational difference between the two enables an estimate of about 500,000 years ago for the common ancestor.
