It's not just Neanderthals -- orges? goblins? -- our ancient but modern-human ancestors were foolin' around with; nope, researchers have evidence they were dating Denisovians (ooh, elves? Maybe?) and one more, unnamed group of hominids, too.
"Mark Thomas, an evolutionary geneticist at University College London, described the ancient environment to Nature as a 'Lord of the Rings-type world.'"
Yes, that's what the man said. I'm starting to suspect that Pratchetts's Discworld novels may be something of a documentary.
