In the middle of the Cambrian, life on land was about to get a little more crowded. And those newcomers would end up changing the world. The arrival of plants on land would make the world colder, drain much of the oxygen out of the oceans and eventually, it would help cause a massive extinction event.

[@vinnie3731]

You're both right and wrong! Algae is a plant, and it's not just an aquatic plant. Here's the literal definition from google. "A simple, nonflowering, and typically aquatic plant of a large group that includes the seaweeds and many single-celled forms. Algae contain chlorophyll but lack true stems, roots, leaves, and vascular tissue".

[@alexbanks4219]

Cyanobacteria is an algae. Blue green algae.

[@brianmader7206]

All land plants descended from a green algae ancestor. So the first colonists on land were probably algal-like, but needed to have certain characteristics (like a cuticle) to live on land. Plants are not algae, Cyanobacteria are not algae (the name blue-green algae is a misnomer). Algae are protists, with their own diverse kingdoms.

[@uvwuvw-ol3fg]

Hopefully next mass extinction will not be caused by ideologies like efilism and antinatalism based on consent. Inherent optimism bias and terror management theory always helps though.

Fr wish all of these paleontologists and scientists would stop wasting time on trying to figure out what ifs about extinct animals and instead focus on building a time machine then we’d know for sure! 😂 If they’re invented in our life times my family and friends would probably never see me again lmfaoo

Just remember, we humans aren't the first species to cause mass extinction. But we are the first to have a choice in the matter.

[@number62]

What choice?

Not really. Everything is going exactly according to plan, and programming.

[@OMGitshimitis]

Can you do a video on conservation palaeoecology? I know it sounds like a very niche topic but I watched a video about how looking at predation scars on modern sea snails can tell us about previous populations of Crabs along the West Coast of America and listening to how the lady who'd done it had come to her conclusions was like watching a detective show- so so interesting!

I would love to see you guys do a video on trilobite fossils since I recently heard that most trilobite fossils are from shedded exoskeletons and I have no idea how to tell the difference between a fossilized shed and a fossil of an actual trilobite.

[@krankarvolund7771]

I'm pretty sure there's no way of distinguish the two, so that might be an assumption from a palaontologist based on almost nothing ^^'
