I'm pretty sure our ancestors never lived in caves. They were just stop-overs that fortunately preserve evidence well - in part because people rarely go there, ironically. Elsewhere, timber and mud brick homes are soon washed away without trace.

@@charlesbrightman4237 There's a cool old sci-fi short story about parents saying goodbye to their kid who is leaving to colonize another planet. The kid's genetic modifications to be adapted to that new planet are described in some detail (I don't remember). The theme is very much about this very alien looking kid still being 'human' and loved by their parents. The twist comes at the very end when it describes the parents slowly walking away on their thick four legs (modifications for high gravity). That's not terribly realistic IMO. I don't think humans will bother settling on the surface of other planet... Makes more sense to just build habitats in space which have exactly the conditions you want. But we will use modified organisms for all sorts of things. Ultimately, materials are all mined, drilled, or grown... And grown is much more flexible/powerful.

Besides mass extinction events here upon this Earth (possibly the 6th has already started due to Earth's magnetism issues), and the 6th won't be the last; b. The Sun is supposed to become a red giant one day and will wipe out all life on this Earth if not even this entire Earth itself. (Sure, a long time from now, but the destination is set like a way point on a journey). c.

I always believed it was possible and never understood why it could not be possible if the molecules are isolated and shielded. A professional geneticist told me that she thought it would never be possible when I proposed the possibility years ago. And, here we are. Nature doesn't care if we think the unlikely is impossible. I think that if it is even minutely mathematically probable, then it will arise somewhere in the infinity of existence.

I think there is something going on with our planet. Where lakes n rivers are drying up they find ancient writing on the cave walls meaning water wasn’t always there. Now they find DNA that shows a warmer climate in what today is frozen over. Pretty amazing how our planet does this shift.
If it was tropical water in this time, then was the Earth's axis possibly at a different angle? Just a thought.

I too thought of this. But I've come to the conclusion that climatic changes are more likely the cause of a warm Greenland. An increase of less than 3° C in North Atlantic Current could raise Arctic temperatures significantly. For 65 million years reptiles had it warm enough to inhabit the entire planet. The glacial period during which our species matured seems, to me, to be the interruption of an overall warm planet since the first thawing of "Snowball Earth". We humans have evolved in a temporary "cold" era, that is (I think) drawing to a close. We filled a niche position in the beginning, for a world growing colder. But are we still as adaptable as our proto human ancestors? Can we cope, even thrive, in a hot world? I believe we are on the verge of answering those questions.

If you're asking that, you're probably aware that the Earth's axis DOES change angle, on a 40,000 year cycle (one of the Milankovitch cycles). But only by about one degree. That DOES play a role in ice ages and other types of global climate change, but by itself it's not enough to drive it. Many other factors play a role as well.
@tinkerstrade3553
Жыл бұрын
@@araptuga I agree. And that 40K year cycle doesn't really correspond well to the ice ages. I'm of the opinion that it is fluctuations of solar output, at least as triggering events. We call our orbit "The Goldielocks Zone" and it is. But we are much closer to the fire than Mars, which is a cold planet. And we have a massive volcanic heating system. It would therefore be logical that we would be a hot, wet, planet a great deal more of the time than a partially frozen one. Think the Amazon Rain Forrest from Florida to the Appalachian Mountains. 👀

Fascinating findings! This is what real scientific research looks like - 15 years of frustration to reach a pivotal moment of breakthrough technology. This video is a tribute to not only these scientists, but scientists of every stripe who are doing real research to help us better understand the past and the future. I would suggest, however, that scientists drop the political buzz phrase "climate change" and instead speak of "environmental change" -- the climate is always changing, and two million years ago, that change had nothing whatever to do with human activity. Science is and should remain above partisan political ideologies.
Ill give folk an idea of this DNA extraction process, it takes over 30 steps to get it out of whatever it is your taking it out of. I had a lecturer in college who was in the process of inventing a new extraction method and our class was the 2nd to be the guinea pigs to see if it worked. It was very difficult and the precision was a nightmare, you mess up one step and you have to start over. We did fairly well considering it was all experimental. We did it twice, once was identifying species from poop, and the second was identifying what had been in some clay pots, ie plant or animal oil.

And so what if some of them were cranial binding it was because there parents had the feature and their hybrid kids didn’t so they were trying to retain it. And I could be wrong but that’s why I’m saying they have better ancient dna testing technology and they haven’t identified the father of any of the samples as far as I know but they all came from the Black Sea region where you have not so far the ancient Sumerian whos religion one of the oldest in the world specifically says just that that they are aliens and the Egyptians of which Akhenaten matches anatomically the paracas not just match but identical and they are found near megaliths all over the world.
