At most, 7% of the human genome is unique to our species

No more than 7% of the human genome is unique to Homo sapiens, according to a study published Friday in the journal Science Advances.

We share the remaining chunks of our genetic material with other human ancestors, or hominins, including our Neanderthal cousins and the Denisovans first discovered in east Asia.

“The evolutionary family tree shows there are regions of our genome that make us uniquely human,” Richard Green, director of the paleogenomics lab at the University of California, Santa Cruz and co-author of the new study, told Insider. “Now we have a catalog of those, and it’s a surprisingly small fraction of the genome…”

“More or less everywhere we look, admixture is not the exception at all, but rather the rule,” Green said.

Of course I find the research fascinating. Not that the admixture of Neanderthal and Denisovan genes [and others] diminishes or alters the Homo Sapiens characteristics. Still, I reflect upon what colors my emotions and judgement from my Neanderthal ancestors. I have 3% directly identifiable genetic material from that stream of evolution.
