Deleted slides ruined this presentation otherwise remarkable. I do not think honest claim about copyrights on the material used for obviously educational purposes.

Hear, hear!

True. Probably diagrams are from research paid for by taxpayers anyway.

Deleted slides and not being able to see where his pointer is pointing at ruined this presentation.

I hope if statistics describing DNA designations of various species reproduceability and other viability aspects can soon be organized to better show alliances in a popular setting. I love seeing taxonomic stuff like this, and all the phenotypical deductions, but better understanding, in the long term, will be vastly aided if all of us, not just a few DNA technologists, can know about details from the genetic end, and can come to understand histories of the genes and how they affect these phenotypes.

But how did plants reproduce before they evolved the abillity to make seeds?

[@spenle]

er... is this a serious question or a joke? I can't tell

[@dagbjarturoskarsson4406]

plants evolved from algae which use spores for reproduction, they continued to use spores for some millions of years til they evolved seeds. Many plants today still use spores. I should note that seeds are a product of spores so all plants still use them but the plants(that have seeds) themselves grow from seeds. please correct me if im wrong
