Researchers, using a technique called molecular clock analysis, have proposed that animals may have originated roughly 200 million years earlier than the fossil record suggests. The finding, reported by Live Science, is drawing attention because it pushes back the timeline of early animal evolution and would mean animals existed well before the evidence preserved in rocks.

Why now: The claim dramatically revises the accepted timeline for when life's first animals appeared, challenging fossil-based views of early evolution.
