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

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

    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.

    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
