The following is an excerpt.
When modern humans left Africa as far back as 70,000 years ago, they dispersed across the world, reaching Australia 50,000 to 40,000 years ago. From then until the 18th-century arrival of European colonists, aboriginal Australians did not mix their DNA with anyone else in the world — or so many scientists believed.
Now a study has turned up evidence of much more recent interbreeding between native Australians and people who came from India. The findings, based on a detailed examination of the DNA of aboriginal Australians and hundreds of people of other pedigrees, found that mixing occurred as recently as 4,200 years ago.
