Scientists build new ‘tree of life’ for placentals, visualize common ancestor Scientists have reconstructed the common ancestor of placental mammals–an extremely diverse group including animals ranging from rodents to whales to humans–using the world’s largest dataset of both genetic and … Continue reading →
Two groups — clades — of grasses that once had a common ancestry diverged. The PACMAD clade was predisposed to evolve a more efficient “C4” means of photosynthesis than grasses in the BEP clade. In a new study in the … Continue reading →
