Different hominin groups lived at the same time. They met, mixed, and had children together. Their DNA is still present in many people today. Neanderthal DNA is part of our genetic heritage. Denisovan DNA is too. This is not only an idea: scientists can measure it in human DNA. That is what made me interested in this subject.
