    The study of natural history is the study of how the world has changed but Earth itself is in a constant state of flux -- because the ground beneath your feet is always moving. So if we want to know how we got here, we have to understand how "here" got here.

    Thanks to Nathan E. Rogers, Julio Lacerda, Franz Anthony and Studio 252mya for their illustrations. You can find more of their work here: https://252mya.com/licensing

    How do you think humans will evolve to become in the future?

    When the continents are all together and subduction is no longer possible, what happens to the mid ocean ridges? And do new subduction zones create themselves near the continental shelves?

    What I find interesting is that this will continue until the core cools sufficiently for tectonics to grind to a halt.
    Of course, we'll be gone because that will also be the end of the Earth's magnetic field. If the sun hasn't swelled and died first.

    There’s a mistake on here. You said Pangea formed 300 million years ago. Pangea formed about 330 million years ago.

    A bold assumption that humans won't have gone extinct in their entirety 250 million years from now.

    sorry, these maps really suck. One example, they show current day shape and size of the Great Lakes and Hudson Bay/James Bay despite that proterozoic eon being 2.5 billion years to 541 million years ago. Even the Great Lakes only 10000 or 20000 years ago were very very very different in size and shape ...

    Know... These videos always show me that we are just another phase of the earth... We'll fade... Maybe by our own doing... Maybe not
    But we'll be gone... And then maybe nobody will remember that we were once here
    Tho.. Maybe another species will rise and find our bone, buildings and Technologie and think "huh... Weird" when they study us
