Final answer:
Yes, researchers found Neanderthal genetic markers in modern human genomes, supporting the interbreeding between early humans and Neanderthals as humans spread out from Africa.
Step-by-step explanation:
It is true that when researchers compared the Neanderthal genomes to the DNA of different groups of modern humans, they found that some Neanderthal genetic markers were present in the modern human genome. This discovery provides evidence of interbreeding between early humans and Neanderthals. The research indicated that early humans who emerged from Africa interbred with Neanderthals and then spread out to populate different parts of the globe. As a result, people living today, particularly those outside of Africa, have between 1 and 4 percent Neanderthal DNA. These findings have important implications for our understanding of human evolution and the contributions of Neanderthal genetics to modern human biology.
