not gonna lie this is relatable

[@Warrior-Of-Virtue]

Here's my theory. We know that the moon is slowly moving away from the Earth. This means that millions of years ago, when the first land animals began evolving, it would have been much closer, and its effects on the Earth, specifically its effects on the tides, would have been much stronger. So animals unfortunate enough to be living in tidal zones could suddenly find themselves miles inland with little to no warning. From there, natural selection did what natural selection does. Animals that could survive for extended periods out of the water had a much better chance of survival. This probably gave rise to the very first mudskippers and semi-terestrial crustaceans who, in turn, gave rise to the very first amphibians and insects, respectively.

I heard the music from Outer Worlds. I thought I accidentally had that game running in the background. :p

[@norarivkis2513]

You said out loud that up to 50% of species vanished in the Silurian extinction, and in the graphic on screen that up to 50% of living creatures died out. (9:16) That's very much not the same thing! Many, many individual living things die in a mass extinction even from species which go on to survive, because in order to survive as a species you don't need your whole population... only enough to successfully breed again. For example, in the K-PG extinction, about 75% of *species* went extinct, but about 99.9999% of *individual organisms* died. The species that survived did so with very few surviving members, who then managed to breed a new population again. (Because I know somebody will mention this: technically, of course, both your statements are correct because of the 'up to', in that if 15% of species went extinct and 49.9999% of living organisms died, both are "up to 50%." But that's not really the way the phrases are used, so it's at least hard to understand correctly, even if not officially inaccurate.)

It actually did. Amphibians and their eggs cannot survive in salt water. They are only found in islands like Hawaii because people brought them there.

[@TheSandwhichman108]

A crucial step in the evolution of life on land was seed producing plants. Before that terrestrial plants reproduced via using spores or by budding which required them to be near water. The first seed producing plants would’ve had a huge advantage over these other plants as seeds contained their own nutrient and water supply which means they no longer needed to be near bodies of water to grow efficiently. Also consider that at the time most of dry land was still a barren expanse of rock,sand and dirt. So in these conditions seed bearing plants would have gone pretty much unopposed as they spread to dryer habitats. This would also allow various other terrestrial organisms like the various terrestrial arthropods,primitive land mollusks,worms and such to also spread further in land.

[@TheSandwhichman108]

@@jameshale6401 I wouldn’t consider it intelligence. I mean plants today will try to grow in and occupy any space they can so it would only be natural for them to spread out as any areas with bodies of water would be extremely competitive.

There is much evidence that the vertebrate lung originated from a progenitor structure which was present in bony fsh. However, critical basic elements for the evolution of breathing in tetrapods, such as the central rhythm generator sensitive to CO2/pH and the pulmonary surfactant, were present in the lungless primitive vertebrate. This suggests that the evolution of air breathing in all vertebrates may have evolved through exaptations. It appears that the capability for proliferation of alveolar type 1 (AT1) cells is the “critical factor” which rendered possible the most radical subsequent innovation-the possibility of air breathing. “Epithelial remodeling,” which consists in proliferation of alveolar cells-the structural basis for gas diffusion-observed in the alimentary tract of the gut-breathing fshes (GBF) has great potential for application in biomedical research. Such a process probably led to the gradual evolutionary development of lungs in terrestrial vertebrates. Research on the cellular and molecular mechanisms controlling proliferation of squamous epithelial cells in the GBF should contribute to explaining the regeneration-associated phenomena that occur in mammal lungs, and especially to the understanding of signal pathways which govern the process.
