Pauline Schaap is a Dutch cell biologist and evolutionary biologist. She is Professor of Developmental Signalling at the University of Dundee.,[1] a corresponding member of the Royal Netherlands Academy of Arts and Sciences, a Fellow of the Royal Society of Biology, and a Fellow of the Royal Society of Edinburgh.
She studies the evolution of multicellularity and cell differentiation in social amoebae.[2]
Schaap received her PhD in 1987 from the University of Leiden.[3] She was a professor at the University of Leiden until 1999, when she moved to the University of Dundee[4] where she is currently a professor.[1] She became a corresponding member of the Royal Netherlands Academy of Arts and Sciences in 2011.[4][5]
Schaap and her collaborators established the first molecular phylogeny of the Dictyostelia.[6] That work showed that complex multicellular fruiting bodies had evolved multiple times independently, contrary to what had previously been generally thought.[6] More recently, Schaap and her team showed that the molecular pathway for multicellular development in dictyostelids had evolved from an ancestral encystment pathway present in single-celled amoebae,[7][8][9] thus contributing to elucidating the molecular basis for the evolution of multicellularity [10]
