Distant relatives

I see in the news today that yet another sub-species of humans has been discovered. Not a living one of course but an ancient one; 50,000 year old bones found in caves in Siberia have had their DNA tested and it turns out to be a completely separate (and now extinct) line of human beings, labelled "Denisovans" after the region they were found in; this makes four known species that existed at the same time as modern homo-sapiens emerged from Africa.


From the sequences in the DNA its is likely that this species interbred with ours so at least a part of their legacy remains in peoples of that region but their main line petered out long, long ago. Just think, their entire species evolved, lived, feared the unknown, loved their children, laughed, cried and probably invented purpose and supernatural forces where there were none for thousands of generations, and then one day they went extinct, without ever hearing the words "Allah", "Yahweh", "Jesus" or even "iPad". Maybe going extinct and allowing another species to take your place is the only way to shed the clutches of ones memes?

I guess that the chances of them hearing the word "Jesus" would be slim in the extreme...But who knows what they passed on or shared with their close relatives? Or maybe it was the lack of a belief gene that did for them - they suddenly realised there wasn't much point in banging the rocks together and gave up?

BTW if "this species interbred with ours" then presumably they're as you say earlier a sub-species rather than a species?

Happy Xmas!

Hi G, happy Christmas to you too, hope you had a good holiday (bit of a busman's gig for you though I expect?)

"Jesus", probably not, they were from Siberia, not Mexico ;)

You know I'm not sure "subspecies" is a real thing, there's probably a better taxonomic word for it?

I dunno about banging rocks, I'm listening to Motorhead's new CD (yes they're still alive!) at the moment, "banging rocks" seems ideal.. :)
