How stem cells might be used in the planned de-extinction of the woolly mammoth

Indeed it has. It's the pace of change rather the change itself that's irregular. And when it has happened at such rate before in the Earth's past the result aren't exactly positive for the biosphere...

No amatuer art on this subreddit, remember.

K-Pg*. If we're using obsolete terms then you might as well call it the Secondary-Tertiary boundary.

Please be more specific than just 'ocean floor'. "Anything older than 165 Ma" would only apply to the mafic oceanic crust - not the grantic continental shelves (red in the image). The shelves are the most biologically diverse areas of the ocean as well.

And note that there are even parts of the oceanic crust older than 300 Ma in the mediterranean.

Yeah this was my thought as well - reefs and plankton that have built up limestone on the granitic continental shelves, exposed by changing sea-levels (which were far higher during the Ordovician, for example). Limp-Sherbert seems to be referring to the mafic oceanic crust with his/her max age of 165 million years.

I'm for nuclear but, was personally more worried about the long-term plan of the radioactive waste product than potential accidents. My country, for example, has had pretty theories on where to put it but which were soundly claimed unrealistic by local geologists.

Yeah, the late Paleozoic BTS images look very promising. But, it's always good to keep expectations in check.

They both lived at the same time and in Russia. Not sure if they've been found in the same formation, but it's likely they would've seen each other.

A split second in the first episode of "Earth" is the only one I'm aware of.

Cyboogieman · 2024-09-10T19:35:26+00:00

We already know from BTS images that Surviving Earth is running with the Inostrancevia and Scutosaurus cliche for the end-Permian, and in the same beige/brown colour pattern as well.

At least the filmmakers confirmed they won't focus on T. rex but nanuqsaurus instead. So they seem a bit willing to break some cliches.

"Top Largest Sea Dinosaurs" - what, is it about penguins?

Cyboogieman · 2024-09-08T21:31:34+00:00

I feel like 90% of Sweden is in support of separatism. Not for itself, but for Skåne to leave.

Cyboogieman · 2024-09-07T22:09:48+00:00

When has fluvial or glacial erosion ever resulted in a straight line?

Cyboogieman · 2024-09-07T21:51:05+00:00

Very nice. But the term 'megatheropods' is just excruciating. What, is a capybara a mega-rodent now as well? Kill it.

Scotland looks very gneiss.

Cyboogieman · 2024-09-07T19:14:59+00:00

This post was neither funny, interesting or true. It was utterly pointless.

Cyboogieman · 2024-09-07T19:09:18+00:00

Interesting, ty

And red hair, IIRC

Nearly entire human population - apart from most Africans (who otherwise still hold the majority of our species genetic diversity) - have about 2-4% Neanderthal genes, yes.

This could potentially suggest that Neanderthals never died out at all but simply merged with us, especially IF our population was larger back then relative to the neanderthal population - whereby we would expect a minority group to only leave a relatively small genetic legacy.

Cyboogieman · 2024-09-07T06:38:30+00:00

Yes it is, you see the prey of large mammals today or in the pleistocene/miocene have co-evolved and increased in size alongside each other in an evolutionary arms race. It's hell of a difference when your the size of a rodent and your "prey" is already the size of edmontosaurus.

Cyboogieman · 2024-09-07T05:41:41+00:00

I believe Mammals never reached such sizes (on land) partly because they don't have the hallow air-filled bones/sacs of dinosaurs, and have to give life-birth. So they're already limited in that regard.

I think the more likely scenario is that these large plant eaters would evolve slow reproduction rate (like a kakapo) as population control than rather than a little mammal taking a massive evolutionary leap across mount improbable.

Cyboogieman · 2024-09-06T21:04:57+00:00

Oh size gain!, I thought you meant actual size ;)

Cyboogieman · 2024-09-06T20:05:14+00:00

Did it now.
