چکیده انگلیسی
Several decades of research provided detailed insight into how genes control development and evolution, whereas recent studies have expanded this purely genetic perspective by presenting strong evidence for environmental and epigenetic influences. We summarize examples of phenotypic plasticity and trans-generational epigenetic inheritance in the nematode model organisms Pristionchus pacificus and Caenorhabditis elegans, which indicate that the response of developmental systems to environmental influences is hardwired into the organismÅ genome. We argue that genetic programs regulating these organismal-environmental interactions are themselves subject to natural selection. Indeed, macro-evolutionary studies of nematode feeding structures indicate evolutionary trajectories in which plasticity followed by genetic assimilation results in extreme diversity highlighting the role of plasticity as major facilitator of phenotypic diversification.
