AI Summary

An international team of researchers has uncovered new evidence about the evolutionary origins of mammalian suckling and milk consumption. Their study, published in Nature, indicates that the anatomical structures needed for suckling, swallowing and breastfeeding first appeared roughly 165 million years ago, predating the emergence of modern mammals. The findings illuminate how a key mammalian trait developed deep in the Jurassic period, offering a clearer picture of early mammalian biology.
