Mass extinctions led to low species diversity, dinosaur ruleRaleigh NC (SPX) Oct 16, 2017 Two of the earth's five mass extinction events - times when more than half of the world's species died - resulted in the survival of a low number of so-called "weedy" species that spread their sameness across the world as the Earth recovered from these dramatic upheavals. The findings could shed light on modern high extinction rates and how biological communities may change in the future. David J. Button, an NC State and North Carolina Museum of Natural Sciences postdoctoral research scholar, and ... read more |
