Scientists used to think that the first animal on earth was something very simple like a sponge, but that assessment has recently been revised. The new thinking is that the oldest animals were comb jellies. This is quite significant since unlike sponges, comb jellies have connective tissues and a nervous system, and are more complex. This means that the earliest animals in the evolutionary tree were already highly developed creatures. This is not what one would expect given the evolutionary view of things, and it's yet another example of nature's propensity for sticking its thumb in the eye of Darwinists' expectations.
The Darwinists are not without explanations for this anomaly, of course, because evolution is a rubbery theory that can be flexed to cover every conceivable observation. Contrary to what one might think, though, this flexibility is not an asset because a theory which can explain everything really explains nothing. It is not falsifiable and is, therefore, not a scientific hypothesis.
Intelligent design is disallowed in public schools on the grounds that it's not falsifiable, but Darwinism, which also seems impervious to empirical falsification, is considered mainstream science. It's very puzzling, to say the least.
At any rate, in honor of the comb jellies' newly-bestowed exalted status we feature this video:
