An in-depth analysis of the fossil record by researchers from the University of Bristol and the University of Friborg has suggested that placental mammals, a group that includes species such as humans, dogs, and bats, evolved during the Cretaceous, which existed temporarily. with dinosaurs before their extinction. (Unlike this artist’s depiction, the earliest placental mammals … Read more

A genetic editing system similar to CRISPR-Cas9 was discovered for the first time in eukaryotes – the group of organisms that includes fungi, plants, and animals. The system, based on a protein called Fanzor, can be guided to precisely target and edit sections of DNA, and could open up the possibility of using it as … Read more
Researchers from the UNC School of Medicine are using evolutionary genomics to understand human diseases. They focus on unchanged, highly constrained genes through mammalian evolution. This new insight allows the tracing of psychiatric and neurological disorders to changes in these genes. This could provide insights into various mental health conditions and potentially allow researchers to … Read more
Truly groundbreaking advances in science are sadly rare occurrences. So when they happen, we should celebrate them. The announcement that scientists have successfully created synthetic embryos from stem cells is one such advance. The breakthrough was announced earlier this month in a plenary address at the annual meeting of the International Society for Stem Cell … Read more

Summary: Orangutans are capable of simultaneously producing two different sounds, similar to human beatboxers or songbirds. Through observations of vocalizing populations of orangutans in Borneo and Sumatra, researchers discovered this shared vocal phenomenon. The findings raise interesting questions about the evolution of human speech and beatboxing abilities. Researchers argue that the ability to produce dual … Read more
Look at the hominin tibia – the enlarged area showing the cut marks. (Briana Pobiner) The bone of an ancient human relative shows signs of cutting with stone tools – of another human relative looking to cut meat to eat. The nine cut marks on a 1.45-million-year-old left shin bone from a relative of A … Read more
