Fat molecules attributed to ancient sea sponges actually belonged to algae, two new studies suggest.

Hundreds of millions of years ago, one of the very first animals on Earth died at the bottom of an ancient ocean. In life, it was a humble sea sponge; in death, it had no bones, nor teeth, nor shell to leave behind as evidence of its brief, bottom-dwelling existence. But it did have fat molecules —  or so it seemed.

Now, it seems that the 635 million-year-old sediment was filled by algae. And according to evolutionists, the oldest ,animal imprint was  roughly 558 million years ago  the fossil imprint of Dicksonian  roughly 558 million years ago.
