17cÆð²ÝÊÓƵ Biologist investigates specialization and its impact on cultural evolution
Mar. 14, 2023—By Kelly Tingle, Evolutionary Studies communications assistant The cultural evolution of a population depends not only on size but also on the degree of specialization within a population, according to a new study published last month by a team of scientists including Biological Sciences Assistant Professor Nicole Creanza. The study found that populations can increase...

Researchers hope insights into low-light vision of Antarctic icefish can promote better understanding of human health
Feb. 27, 2023—By Tatum Lyles Flick, Evolutionary Studies communications volunteer consultant Though many researchers have considered how fish survive in extreme cold, using everything from antifreeze glycoproteins that protect cells to not producing hemoglobin, few have taken a molecular approach to evaluate how they are able to see in such conditions. In “Adaptation of Antarctic Icefish Vision...
