This week I finally make it to the dawn of complex life and many or the animal groups that we know today. It's still quite a strange world, but this is a critical point in our plenets history, the Cambrian Explosion. during this event, there was a massive increase in the biodiversity of the Earth withing just a few million years. This would set the stage for everything that has yet to come.

I've been a sub for some time. I love your content. I have MS and there are times it's difficult for me to follow along with other channels. It's easy to follow along and understand everything.
If you know anything about MS it causes brain fog or "cog fog". These are issues with your memory, attention span, understanding or concentration. Some days are harder than others. Thank you for all of this!!

I love earth history in relation to early life.. it's just so unreal going back to the formation of various body shape designs all determined and adapted by their environment and survival pressures, it's really fascinating like some automated process driven by selective pressures, while amazing to see changes throughout history, leading to life as we know it today.. it's also a terrifying thing, a winnowing, a sifter of living bodies, it's really a system built upon past failures as a result of death and disease etc.. all of us are vulnerable to, yet still from a biological stand point absolutely fascinating..

but when you see such things, such as the fossil record and come to life through animation such as videos it really puts things int perspective (for me personally) it makes you truly see things for what they are.. my conclusion to it all, remains the same lately "it just is" the appearance of our universe, the cosmic evolution, biological evolution etc.. it all "just is" and for me, I am satisfied with that answer..

8:06 Attach that thing to your spine. I heard it gives you superpowers, like the ability to shift into titans or something like that.

Opabina is charismatic, batting its 5 eyes @ U, & somehow reminds me of a dragonfly nymph

FYI, The first fish is the Haikouichthys and the first chordate was the Pikaia.

Hi i’m working on my own alien planet. I’m making a new planet because I got really bored of the other one and cancelled the series. I’m gonna make another one I’m gonna start pretty early on in the planets history how complex should they be?

English speaking people have strange way of pronouncing the word "Chordata", and other Latin names.
There is no letter "k" in "Chordata" :)
