Nothing in post #256 states it is the oldest DNA.

Who is this guy anyway?

That's a vid by Aron Ra, he's one of the youtubers who's been posting sciency videos.  Did an excellent series on creationism and evolution.    I saw him refer to the story a few days ago, in other versions of the story the dna was stressed as being the oldest ever; 800 k years.   But that wasn't quite right.   

My bad.   I didn't read your story's source, just presumed it was one of the erroneous ones.

Oldest ever human genetic evidence clarifies dispute over our ancestors

Summary:
Genetic information from an 800,000-year-old human fossil has been retrieved for the first time. The results shed light on one of the branching points in the human family tree, reaching much further back in time than previously possible.

...

"Ancient protein analysis provides evidence for a close relationship between Homo antecessor, us (Homo sapiens), Neanderthals, and Denisovans. Our results support the idea that Homo https://www.sciencedaily.com/releases/2020/04/200401111657.htm

The dental proteome of Homo antecessor (PW)

Not the oldest DNA, it's a study that talks about the proteins found on ancient teeth.   Sorry, but this story is just bad reporting according to Aron Ra, anyhow.

Sick. Sociopathic.

Two words that describe every empire in Earth's history.

It's going to
disgustingly more humid than it used to be = a consequence of global heating, s

Qu: Have you checked the temp against previous years ? Cold & clammy feels much colder than very cold but dry?

I've lived here for over 50 years.   :)   It's Edmonton, Canada.   I  have checked, and the humidity does seem to be higher, and so are the consequences.   Some old woods seem to be re-humidifying, but that could be wishful thinking on my part.   The other 'tell' is the lack of nosebleeds, tbh, the dry winters used to make my nose bleed every year; that stopped in 2005ish.   

One year, I spent a winter in Halifax, NS; I never complained about dry colds after that.    Until the winters here started to get 'wet'.   

Thanks again for the work you're doing on gathering this data.

Yes, I've always liked films like Mad Max, and reading books about such tripe.  It would be awesome to live as our savanna dwelling ancestors did.   After all, aren't you enjoying the mix of Nineteen Eighty Four and the Handmaid's Tale?

This sort of questioning thread is a bit of a stretch, isn't it?   :)

Arctic sea ice / Re: Are you hoping to witness a BOE?
« on: August 23, 2019, 12:28:40 PM »
Unless I die in the near future, I expect to see one.   

Hope has nothing to do with it.   The question is 'wrong', it's an emotional question, not a 'scientific' one.    Hope is a form of belief, and that's not something you do with scientific things.   Scientific theories and hypotheses (even vague speculations) are things you accept, or reject.   IMO anyhow.

I don't think that a BOE will affect those who are committed to continuing the burning of fuels, they're making money and are 'religiously' certain that there will be technical solutions to any problems that humans encounter.

So if the correct answer to the Fermi paradox is, we don't see aliens because it's a rare thing that civilisations make it through the atomic bottleneck, it strikes me as an extremely positive message for us humans. We made it!


The nuclear arsenals of at least two nations are still on a hair trigger alert.   An unobserved asteroid hitting the planet could set off a catastrophe, or a simple accident aboard a ship or in a missile silo/nuclear weapons factory could do the same.

We've made it so far...   That doesn't mean we've passed the point at which our survival is guaranteed.   :(   Keep the champagne in the cellar, hopefully one day we can put it on ice and drink it.   :)
