Old American theory is 'speared'

[Anomalocaris]

Hmm, of all the populations outside of Africa, Andeman island population in the Indian ocean seem have retained a distinct linguistic and genetic heritage unmixed with other population for the longest period, about 60,000 years. Andomanese are thought to be the direct remnants of the original population that would later found the Australian abriginie population. Recent genetic evidence suggests before arriving in Australia, ancesters of the abriginies absorbed genes from newly discovered native denisovan population in south Asia. Andomanese have no denisovan genes. This suggests andomanese population have been genetically isolated since before ancesters of abriginies completed their stay in coastal southern Asia and set out for Australia.
