Hello and welcome! My name is Anton and in this video, we will talk about a study that discusses the idea behind animals turning into crabs through evolution.

    You keep using the word species incorrectly you also incorrectly stated that marsupials aren't mammals they are mammals they just aren't a placental mammals

    Marsupials are mammals and not an example of parallel evolution. Also you completely misinterpreted the pleon changes, they do not invert. The pleons are tucked under the body, not inside. Please correct all these mistakes at least in the description.

    Evolution works with what it has available. It's not true that similar environmental conditions are the explanation for convergent evolution, because that evolution depends upon preexisting morphology. As was pointed out, the convergence on crab like morphology is only exhibited in crustaceans, who _are_ related phylogenetically, and therefore share the kinds of morphological traits that are amenable to that convergence. Presumably crab like crustaceans share habitats and ecological conditions with species that are not converging on crab like morphology. This is because they don't possess the suite of traits (or more specifically, the underlying genes) that allow for evolution in that direction. The environment produces selection pressures, but what is selected for is limited by preexisting genetic information. It is not correct to say that crab like species are not genetically related, since they are all crustaceans.

    Something that is extremely cool if you're ever lucky enough to find one is a tiny arachnid called "Pseudoscorpions" or more commonly, "Book Scorpions" or what I was taught as a kid, "Scorpion Fleas". They actually look just like a tiny scorpion with no tail and stinger. The ones I've seen were just bigger than a ghost ant with dramatically wide set, tiny pincers. They're totally harmless (to humans) little scavengers that prey on common household pests like carpet beetles and book lice. I've only ever seen two in my whole life, but supposedly they're very common. Basically, they're spiders trying to be crabs. :-)

    In the tree of life (or "bush" if you prefer Dr Stephen J Gould's analogy), there is a branch that contains all the beings we call "marsupials", and we call that branch "Marsupialia". That branch is ultimately a sub-branch of another branch "Mammalia" that contains all the beings we call "mammals". There are other branches that stem from the Mammalia branch with beings that look very different from marsupials of course. But there is no escape given both our "classic" (with paraphyletic terms such as "reptile" which are almost meaningless now) and modern definitions, all marsupials are mammals. As are we.

    This is the dumbest most ridiculous thing or notion I have ever heard. Evolution has been debunked more times than just about any theory that exists in the Scientific community by more and more actual Science. The only thing that supports it is more pseudoscience theories. This particular take on it is down right laughable. Hilarious video man. Seriously a great troll of "evolution."

    Parallel evolution of lizards, mammals, and fish: If you saw an ichthyosaur in the ocean, you would assume that it was a dolphin, they look so similar and would behave similarly (e.g., holding their breath), but the lizard's tail would resemble a fish's, as would its lack of eyelids. And the fish, unlike the mammal and lizard, did not start out with four legs. :-)
