Hear about the girl that was part Neandertal and part something else?
gpt
Yea, it was a 13 year old girl that was also part Denisovan
human
They found it all from a finger bone too.
gpt
Yea, it's pretty wild that there was another species of humans cross breeding with Neanderthals
human
Seems like the Denisovans were an obscure offshoot of a common ancestor. Split off like 400,000 years ago.
gpt
It's amazing how molecular geneticist were able to discover the Denisovans by looking at it's DNA
human
*raises eyebrows* Yeah from a single genome too.
gpt
It's so fascinating that Denisovan and Neanderthals shared the same cave, I wonder how they reacted when they first saw each other
human
*smiles* I guess they didn't distinguish that much. Seems like they intermingled with more modern humans too.
gpt
Yea, some scientists do not even consider Neanderthals, Denisovans, and modern humans separate species
human
The first humans appeared around Africa about 315000 years ago.
gpt
Humans also didn't lose their body hair until 240,000 years ago
human
Some humans are still pretty hairy. We started modernizing about 50,000 years ago, tools and clothes and such.
gpt
Yea, before that humans were adapted for persistence hunting making us great distance runners
human
Pretty amazing. There's a good book about that actually, Born to Run.  In the grand scheme of the universe we've been here a very short time. The earth started forming 4.5 billion years ago.
gpt
It's a shame that 80% of natural forest have been destroyed by humans
human
*shoulders droop* That is very sad. It's not like we have a lot of planrts we can go to close by if we mess this one up. Not like we could live on the planet that precipitates glass sideways at 4500 mph.
gpt
I'd rather live on Venus despite it not having any seasons
human
Well, if you don't like tilting planets and seasons then that's the planet for you.
gpt
Well it sounds better than Uranus which rotates sideways
