a. 4500
b. 4600
c. 4700
d. 4800

ANSWER: 4500
 
Researchers from the University of Cambridge have sequenced an ancient African genome from 4500 year old skull in Ethiopia confirming mass migration wave from Eurasia to Africa close to 3000 years ago. 25% of the DNA of modern Africa can be traced to this event and data shows Africans carry a considerable component of Eurasian ancestry. The research findings indicate mass migration of western Eurasians into Africa around 4000 years back originating in ancient Middle East. This marks the first time an African genome has been decoded.
