i looked up the number of deaths during the napoleonic wars like yesterday

They were dropped off by aliens. The very same ones who returned millions of years later to build us pyramids. It’s a very philanthropic extra-terrestrial community

Fuck this moron.

I think it means we don't know what the ancestors of those plants are/what they evolved from. They just kinda showed up in the fossil record.

That the fossil record is incomplete

It means our knowledge of their ancestry cuts off at that point. Anything else is speculation without additional information.

Imagine you are trying to infer the structure of a tree by only know the positions of its leaves. Now imagine doing the same, but only 1/100 of the leaves are above ground.

It's only a small fraction living organisms which remain alive today. Most species and families which have ever been are extinct. And most are so old we could never do DNA work on them. Among the living, we can do some good DNA work and that's made a huge difference. But then go back far enough and there are just massive nonconformities.
