How did Life Come onto Land?

Life on our planet originated in water. This assumption forms the basis of the biogenesis theory today and is practically beyond any doubt in the scientific community. It is water in its liquid state that offers the best conditions for life to originate and evolve in. However, if we were to cast our gaze around, we would see various organisms not only in oceans and rivers, but also on the planet’s surface, in the soil, in the lower strata of the atmosphere and even in the mouths of volcanoes. When and why did life break away from the hospitable ocean and move on to exploring forbidding barren land? Let’s try to get to the bottom of it.

If my ancestors figured out how to crawl onto land, I can crawl out of bed today

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.

"Many were increasingly of the opinion that they'd all made a big mistake coming down from the trees in the first place, and some said that even the trees had been a bad move, and that no-one should ever have left the oceans."

I would like to go back in time and see how everything came to be up to this point. Cause I’m sure life at the beginning will be a sight to see

There are fishes "learning" to live on land right now. Mudskippers, giant mudfishes... There are about 30 families of fishes able to survive on the surface. Some of them for a few hours, some for days or weeks.

I read in a book recently that the main reason life came onto land from water was the evolution of a new and dangerous predator known as the shark.

Thank you for adding the chart on the left side of the screen. Thank you presenting
the theory as to the cause of the other mass extinctions: evidence of the other impact craters.

This is the first time I viewed a Kosmo video. I must say that it a fine surprise. There a few good documentary channels on YouTube. Kosmo seems to be one of them. I have subscribed and I look forward to discover the rest of the channel content. Thanks for all the work you have put in.

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

[alexandermartin]

*Kosmo and The Exoplanets Channel are my favorite channels!!*

[Maxiloup]

This is fascinating for a relax Sunday

[claudekingstan]

Saving this to my favorite for my son, grand child and great grand child.

[Atari_collector]

I like how this guy has the outer worlds title theme playing I’m liking this guy already

[adrianokury]

Superbly conceived and beautifully executed! Super thumbs up.... and my subscription.

[whirledpeas]

This is going to be another million views video, Great work.

[Le_cuisinier.du-chienne]

Yet the guys who kept knocking on my door keep insisting we came from dust and rib..

[norarivkis]

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.)

Not only do aquatic organisms evolve into land organisms, our Lifeform Material is designed so that plants evolve into simple animals, who gradually become more complex.

That's because some planets don't have oceanic gas layers.

We will evolve into the aliens that we so long to encounter
