A change in evolution theory we come from sponges?

[Justtristo]

In a prehistoric version of "the chicken or the egg" question, researchers have long debated which animal group came first. A traditional view pegs sponges—marine creatures that look more like rocks or corals—as our ancient ancestors.

But a new genetic study is stirring the waters, suggesting comb jellies, gelatinous marine animals that look similar to jellyfish, are actually the first animals to have evolved over 600 million years ago.

Now this is not been thought peer review so we will have to wait for conformation.

I find it more amazing that animals such as comb jellies have changed quite little in 600 million years.
