The 3D animations are FANTASITIC. There’s a decades long gap in my heart from when Walking With series stopped putting out CG animation. It really helps the public visualize the past, and gives them a reference point. Also thank you for putting out so many invertebrate centric videos. Invertebrates are so interesting, but are talked about so less often.

This hypothsis dovetails nicely with the ideas that logs ejected into the oceans by rivers, also have similar functions, providing floating islands that can provide a platform for attaching larval barnacles & algae, creating life laden islands in the desert of the pelagic.

Part of me wonders if, in the far distant future, we will wind up doing something similar on a planetary scale. Using materials and resources gathered from across the entire solar system, we build something like a Dyson sphere to encase the sun itself, building our civilization on the inside of the sphere, and then launching the sphere across the galaxy in search of new systems to colonize, and possibly even to other galaxies entirely.

@michaeldougherty6036 20 дней назад

My only problem with this hypothesis is: chitin doesn't float. Dead arthropods may float for a bit after death, but they are generally picked off by scavengers. An individual plate of chitin would not be prone to float, unless archeologists could show that some of these species' plates had air pockets for ballast or something.

“What is the Ediacaran period named after?” My genuine first thought was a mountain range, but I couldn’t place it on my mental map, which made me realize two things. First, I am poorly learned of Australia’s geography, and secondly, I have no idea how I knew that. Time to do some knowledge diving, it seems.

@colterflynn1782 4 месяца назад

What if there is just a ton of small arthropods currently mixed into the water column and these picoplankton have evolved to access the nutrients therein AFTER spreading into the deep oceans? Do the authors cover the case where bacteria spread first and then started to utilize arthropod detritus as a way to gleam extra carbon from their desolate environment?

It's so weird to think that there was a time when you would walk across barren rocky land, come to a seashore of thriving life, turn around and walk back... and there'd be this barrier in the ground of inert minerals, and microbes slowly working their way through. I mean, in reality, they probably spread quickly via rain and whatnot, but I do wonder what the last patch of earth to be truly lifeless was. I mean, that COULD have life in it.
