Why do people live so long? A new study suggests that a mother’s care could be an important part of that. The Cornell University study says the reason humans and other primates live so long can be at least partially explained by the mother-infant relationship. Maternal care leads to the evolution of “long, slow lives,” … Read more
Scientists have discovered a 246-million-year-old fossil of a marine reptile, the oldest of its kind found in the Southern Hemisphere, shedding new light on the early evolution of marine mammals. The largest mass extinction in the fossil record – known as ‘The Great Dying’ – occurred around 252 million years ago, wiping out around 95% … Read more

Resume: Humans may have evolved complex facial expressions to enhance social bonding. Analyzing more than 1,500 natural conversations, the study found that expressive individuals were more liked and better at achieving social goals. Expressive participants were easier to read and more successful in conflict negotiations. This suggests that facial expressiveness plays a crucial role in … Read more

Astronomers have discovered an unusual exoplanet that has managed to maintain its atmosphere despite intense nearby radiation from a giant red star. Researchers at Johns Hopkins University found that the rare planet, which should have been stripped to rock by radiation from its nearby host star, instead developed a puffy, less dense atmosphere. The planet, … Read more

Recent research on stick insects shows that genes associated with lost traits may be conserved across evolutionary timescales due to their multiple roles in biological processes, allowing for the potential reemergence of these traits. This study sheds light on the complex genetics of trait maintenance and reemergence, and points to broader implications for evolutionary biology. … Read more
