Peter Ward from NAI’s Alumni Team at the University of Washington and his collaborators have a new paper out in PNAS providing supportive evidence for Romer’s Gap. Their results link this gap in vertebrate terrestrialization with a low atmospheric oxygen interval. This paper supports Ward’s new book on the evolution of effective respiratory systems, entitled “Out of Thin Air.” [Source: NAI Newsletter]
