Adam was from Cameroon!!! (aka: "The Y Chromosome World Map")

Check out this map of the genetic diversity of the Y chromosome (basically, how it migrated through the world)

(via Wikipedia)
Interesting info from the above :

• Adam came from Cameroon based on the A0 and A00 haplogroup
• The predominant Greek haplogroup (E) is most commonly found in Africa (remember, Greeks are "white", whatever that means)
• Continuing on "whiteness", the predominant European haplogroup (R) is also all over west/central Africa
• And Egypt is a mix of European and African haplogroups, which pretty much makes sense 'cos thats pretty much where everybody had to go through to get out of Africa and go anywhere (and vice-versa!)
