The oldest human genomes ever sequenced reveal that our Neandertal ancestry came from one “pulse” of interbreeding and pins down the timing ...

But the details of that evolutionary history have remained unclear. How often did ancient humans and Neanderthals interbreed? Exactly when did that happen? Why did Neanderthals go extinct ...

Johannes Krause, a senior author of the study, noted, “These results provide us with a deeper understanding of the earliest pioneers that settled in Europe. They also indicate that any modern ...

In high school biology we are told that species are communities of individuals that can interbreed successfully. Two creatures that cannot interbreed, even if they resemble each other, must belong ...

As long as the individuals in a population have the opportunity to interbreed and combine genes, they remain one species. A population of one species can only evolve into more than one species if ...
