Collagen-eating microbes may explain fossil record gaps

Original: Rise of collagen-eating microbes may help explain gaps in the fossil record

University of Cambridge researchers suggest that the evolution of microbes capable of digesting collagen, the protein in bone and skin, may explain why many ancient animals left no fossils. As such microbes spread through ancient oceans and soils, soft and skeletal remains decayed faster, leaving fewer traces. The idea is drawing attention as a potential answer to long-standing gaps in the fossil record.

Why now: A new Cambridge research finding offers a novel explanation for a well-known scientific mystery.
