Environmental Graffiti Will be Changing Dramatically Soon. Get a Sneak Preview By Signing Up Here.
As so often happens in research, years and years of effort have been expended operating under the assumption that the sea sponge is the animal at the base of the “tree of life”, only to find out that that assumption is completely wrong.

In an announcement baffling scientists, a team investigating the matter has claimed that the comb jellyfish actually holds that distinction.
The team, which has reviewed its findings repeatedly, is going to publish this research in Nature. This has resulted in but one conclusion for the time being: the comb jellyfish came first. This may seem improbable because the jellyfish has connective tissues and a nervous system, unlike the sea sponge. It also may imply that the less complex version of the sponge, and therefore the rest of life, would have evolved from the more complex jelly.
That possibility alone is certain to get miles of play from the intelligent design and creationist crowds, who have managed to forestall the teaching of actual biology in American high schools for years.
With the possibility of scientists having to regroup a bit, one would expect a renewed offensive. To which I hope we can all reply, science has never done this with a straight face:
