Interbreeding between modern and archaic humans

> A 2023 study found an introgession from modern humans to Neanderthals around 250,000 years ago

The article also mentions a study that suggests Neanderthal Y chromosome was introduced from modern humans in a later event.

There's no physical evidence of either of these events, but they make the modern human migration out of Africa much more puzzling.

Man, they're really pushing this. People are people, except Black people. They have not quite evolved with the Neanderthal/Denisovan "upgrade". Probably flagged, because I may be sarcastic, but some will believe it to be so . Archeology can be such a farce. Find bones, make up story. No wonder it's littered with so many gaffes.
