Collagen-eating microbes may explain gaps in the fossil record
Original: Rise of collagen-eating microbes may help explain gaps in the fossil record
University of Cambridge researchers report that the evolution of microbes capable of breaking down collagen may help explain why ancient animal remains are missing from the fossil record. The idea suggests that as such microbes spread, soft tissues and bones decayed faster before fossilisation, leaving fewer traces of early life. Scientists are weighing how this changes interpretations of gaps in the fossil record.
Why now: New Cambridge research offers a fresh biological explanation for long-standing gaps in the fossil record.
