The researchers report a more complex effect, and it’s all about exactly how much O2 was available to some of our earliest multicellular ancestors. The Geogia Tech researchers with the School of Biological Sciences are G. Ozan Bozdag, research scientist; Will Ratcliff, associate professor; and Rozenn Pineau, Ph.D. student in the Interdisciplinary Graduate Program in Quantitative Biosciences (QBioS). Joining them is Chris Reinhard, associate professor in the School of Earth and Atmospheric Sciences.
