Grandpa Sponge

Filed under: Posts — clgood @ 8:08

If creationists don’t like to admit that we’re apes, they’re really not going to like this. Fascinating story, though. Be sure to check out the illustrated steps.

However, sponges seem unlikely ancestors. They are little more than a loose assemblage of cells that lack the true tissues and organs found in higher animals. Plus their structure – a porous mass of interconnected water channels – is nothing like that of any other animal. As a result, most zoologists tend to put sponges on a side branch of the animal tree, an abortive experiment that led nowhere. That’s what makes Kevin Peterson’s results so thought-provoking.
