The environment plays an active role in the construction of form and function during development. As such, it can play an important role in the production and inheritance of phenotypic variation. Three areas of this new approach to development and evolution will be discussed:
– Developmental plasticity, wherein signals from predators, diet, sunlight, and conspecifics can alter a developmental trajectory towards one of greater fitness. Models, such as genetic assimilation, predict that such environmentally induced changes can become fixed into the genome.
– Developmental symbiosis, wherein organisms co-develop and need the signals from another species in order to develop normal parts and bodily functions.
– Epigenetic inheritance, wherein environmentally induced conformational alterations to the chromatin (DNA methylation, histone acetylation) or to other cellular components can be stably inherited from one generation to the next.
In the seminar we will discus the evidence for these interactions, the relationships that these views have for redirecting our studies of evolution and development, and the possible medical and philosophical relevance of these views.
