DNA study reveals a percentage of the human genome isn't 'human' - TweakTown

The researchers behind the study used publicly available genome data on the modern human, Neanderthals, and Denisovans to construct an evolutionary family tree for homo sapiens.

Using the ancestral recombination graph, the researchers discovered the shared regions in the human genome and the ones that were unique to each group.

Speaking to Inverse, Nathan Schaefer, a bioinformatician at the University of California, San Francisco, and the paper's lead author said, "If you sequence a bunch of people, you could make a tree that would show how everyone's related, on average, across the whole genome." It was discovered that between 1.5% and 7% of the modern human genome is unique to our species.
