A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

This is a science community. We use the Dawkins definition of meme.
So Darwin was trying to explain how creatures with common lineage appeared both sides of an ocean. He "proved" that the land masses were once joined. He didn't really care so much about "how" they were joined, but it was vital to his theory of evolution that they were.
Oh, definitely. It's also worth noting that he definitely wasn't a geologist, despite having an interest in it. I was mostly just mentioning it because there were theories trying to explain the similarities across landmasses before plate tectonics. We may not always be right about why, but we're really good at noticing stuff like that (even when it doesn't mean anything).
