A new study has uncovered evidence for a previously-unknown species of archaic human that may have contributed to the genetic makeup of a group of people living in modern-day Sub-Saharan Africa.

"It seems that interbreeding between different early hominin species is not the exception — it’s the norm," explains assistant professor of biological sciences Omer Gokcumen, PhD, with the University at Buffalo College of Arts and Sciences.
