My new paper addresses the evolution of hagfish slime thread and the thread cells. It shows the largest cell size allometry in animals known. The results suggest a significant impact from body size-related selection (via predator-prey interactions) for the evolution of slime threads. See interviews by The Scientists and SYFY Wire.

Evolution of flight morphology in stick insects
The origin of insect flight presumably underwent a series of intermediate morphologies, which, unfortunately, has not been shown in the fossil record. However, we can infer such transition by studying extant insects undergoing secondary flight reduction. In this new publication (link), we presented a framework for describing the evolutionary pathway between winged and wingless (volant)... Continue Reading →
