If there's one thing that most of us can broadly agree on, it's that the world is a very complex and beautiful place. It can be hard to appreciate just how mind-blowing all its natural resources and creatures are, unless we've spent enough time in the company of the Discovery Channel. One of the most astonishing things about life on Earth is how all living beings are connected in some way, but the linkage isn't always as obvious as you might think.
This revelation was recently explored in a thread started by @limitlessjest, in which suggested that alligators and crocodiles had little genetic relation. This kickstarted a revelatory thread that exposed just how many similar-looking species actually could not be considered as close relatives. While some pointed out that the original tweet was a little misleading in terms of the histories of our scaly friends, there were still some interesting points to be made about the craftiness of the evolutionary process. Main takeaway: if in doubt, return to crab.
