Scientists have suspected that modern humans have more genes to digest starch than our hunter-gatherer ancestors, but the amylase locus of the genome is hard to study. Researchers have now developed new methods to isolate the multiple amylase genes and compare the locus to ancient genomes. They found that amylase gene number has increased from an average of eight to more than 11 over the past 12,000 years ..read more

Researchers have uncovered a surprising genetic mechanism that influences the vibrant and complex patterns on butterfly wings. The team discovered that an RNA molecule, rather than a protein as previously thought, plays a pivotal role in determining the distribution of black pigment on butterfly wings ..read more

The largest dataset of cetacean genes ever collated has helped scientists deep dive 'into the blue' to fathom the 'triumph' of baleen whale evolution. The new study explores the key genetic adaptations of these diverse whale species around the world's vast oceans -- giving new insights into the risks and opportunities for their survival ..read more

The research cracks the code on the iconic baobab tree's origin story, revealing their surprising origins in Madagascar and incredible long-distance dispersals to Africa and Australia. The study unveils how baobabs developed unique pollination mechanisms -- some attracting hawkmoths, others lemurs, and even bats -- showcasing remarkable evolutionary adaptations. The research sheds light on how climate change has shaped the baobab's distribution and diversification over millions of years, offering valuable insights for understanding plant responses to future environmental shifts ..read more

Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil record has gaps and is incomplete, and we're missing data that we need to reconstruct evolutionary history. Now, a team of sedimentologists and stratigraphers examined how this incompleteness influences the reconstruction of evolutionary history. To their surprise, they found that the incompleteness itself is actually not such a big issue ..read more

A link between outgroup threats and ingroup cohesion has been considered since the time of Darwin to be an adaptation for group-based competition. During the years since, studies of all sorts -- from chimpanzees to cichlid fish to mongooses -- have found evidence supporting this view, but a crucial question has remained unanswered: what about species without strong inter-group competition ..read more

Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life ..read more

New research shows that rainwater could have helped create a meshy wall around protocells 3.8 billion years ago, a critical step in the transition from tiny beads of RNA to every bacterium, plant, animal, and human that ever lived ..read more
