Earliest known DEvolution in an animal at 518 mya

The worm lost its back legs and built itself a tube to live in instead:

Facivermis yunnanicus was a worm-like creature from the Cambrian period, when the first complex animals evolved in the seas. It was under 10 centimetres long and had five pairs of spiny legs on its front half, while its rear end was swollen.

Paper. (open access)

So yunnanicus started out more complex and evolved to be LESS complex. Maybe Darwinism can explain that more easily than it can explain most evolution because we are looking at a loss of information.

    It has previously been hard to determine exactly what kind of animal F. yunnanicus was. “People have said it’s all kinds of things over the years”.

    Of course a bunch of monkeys’ cousins dressed up in labcoats (a.k.a. scientists) can not know anything .
    Our brains are very poorly designed. Our whole body is a botched job.

    Misconceptions about evolution
    ”Evolution results in progress; organisms are always getting better through evolution.”

    Stephen J. Gould wrote several essays about this misconception too.

    One of Gould’s essays showed that for mathematical reasons it does on average result in progress, at least early on, but on average does not mean monotonically. He wrote that like 40 or 50 years ago, it’s pretty common knowledge among biologists.

    The BIG PROBLEM for naturalism is that, under a materialist/ evolutiveparadigm, it can not coherently explain the concepts: ‘better’, ‘progress’.
    ‘Better’ for what? If there is not purpose, there can be neither betterment nor progress.
    Stuff happens.

    It is pretty common knowledge among rational people that naturalism is a barrage of non-sense and glaring contradictions. Day in and day out.

    Jim Thibodeau, thank you for demonstrating the universal common descent is a pipe dream.

    I’m not sure that building a tube should be considered devolution. It’s super-common as a strategy, but it takes more planning and anticipation than just moving around. Among familiar critters like birds and humans, we regard nests and houses as signs of intelligence.
