Evolutionary changes of developmental mechanisms in the absence of cell lineage alterations during vulva formation in the Diplogastridae (Nematoda).


The origin of novelty is one of the least understood evolutionary phenomena. One approach to study evolutionary novelty comes from developmental biology. During developmental cell fate specification of the nematode Pristionchus pacificus (Diplogastridae), five cell fates can be distinguished within a group of twelve ventral epidermal cells. The… (More)
