I have posted occasionally here about the back-and-forth over whether or not Homo sapiens sapiens (that would be you, reader, probably) interbred with Neanderthal people or not. Now the verdict seems to be yes, to some extent.
Complicating the issue is the discovery of another group of archaic people, the Denisovans, whose genetic legacy is found in New Guinea.
Since New Guinea is famous for its huge variety of native languages ... nah, that would be expecting too much.
(The kool kids now say "hominin" instead of "hominid," but it means about the same thing.)
