A Genetic Ghost Hunt: What Ancient Humans Live On In Our DNA?

When the Denisovan genome was sequenced soon after, in 2012, it revealed similar instances of interbreeding. We now know that small populations from all three Homo lineages mixed and mingled at various times. The result is that our DNA today is speckled with contributions from ancient hominin groups who lived alongside us, but did not survive to the present day. Genes from Denisovans and Neanderthals are not present in everyone’s DNA — for example, some Africans have neither, while Europeans have just Neanderthal genes. But, these genetic echoes are loud enough to stand out clearly to scientists.

Revolutionary War hero Casimir Pulaski might have been a woman or intersex

INTRO

Casimir Pulaski, hero of the Revolutionary War and the pride of the Polish-American community, may need a new pronoun — he may have been a she, or even a they.

Researchers who used DNA to identify Pulaski’s bones are convinced the gallant Pole who died fighting for America’s freedom was either a biological woman who lived as a man, or potentially was intersex, meaning a person whose body doesn’t fit the standard definitions of male or female.

BBC: How ancient DNA may rewrite prehistory in India

New research using ancient DNA is rewriting prehistory in India – and shows that its civilisation is the result of multiple ancient migrations, writes Tony Joseph.

Who are the Indians? And where did they come from? 

In the last few years, the debate over these questions has become more and more heated.
