About Mark Pagel
Mark Pagel is the head of the Evolution Laboratory in the biology department at the University of Reading. Pagel builds statistical models to examine how evolutionary processes imprint in human behavior, from genomics to the emergence of complex systems to culture. His latest work examines the parallels between linguistic and biological evolution. Pagel argues language is a culturally transmitted replicator with many of the same properties we find in genes.
