Researchers using molecular clock analysis, which estimates when species diverged based on genetic mutation rates, have proposed that animals first originated around 200 million years earlier than the fossil record suggests. If confirmed, the finding would push back the timeline of early animal evolution substantially and reignite debate between genetic evidence and the physical fossil record.

Why now: New research challenging the established timeline for the origin of animals is a striking scientific claim.
