Only 7 percent. The human genome is unique to our species. Most of our genes correspond to the genetic code of Neanderthals, Denisovans (a species of hominid discovered several years ago in the Denisov Cave in the Altai Mountains) and other human ancestors.

  • Only 1.5 to 7 percent. According to the latest research, the human genetic code is unique to our species
  • Neanderthals, Denisovans, and other Homo sapiens ancestors had many of the same genes we have today.
  • The unique genes of rational humans play a role in the process of brain development, which may be what defines our species

More than 90 percent of the human genotype is similar to genes, among other things Neanderthals. As it turns out, a small percentage of the genetic code is unique to the rational human race, It has to do with human brain function and social skills such as communication.
