Earth and Environment - Palaeontology
Scientists at the Universities of Oxford, Exeter, Yunnan and Bristol and have discovered the oldest fossil of the group of animals that contains earthworms, leeches, ragworms and lugworms. This discovery pushes the origin of living groups of these worms (polychaetes) back tens of millions of years, demonstrating that they played an important part in the earliest animal ecosystems.
A research team involving UCL has discovered an earlier origin to the human language pathway in the brain, pushing back its evolutionary origin by at least 20 million years. Previously, a precursor of the language pathway was thought by many scientists to have emerged more recently, about 5 million years ago, with a common ancestor of both apes and humans.
