The Interaction of Evolution and Development in Biology ("Evo-Devo")

Long ago, biologists like Bonner, and the even earlier J. H. Woodger, advocated thinking of the whole four-dimensional developmental sequence or program as the phenotype-which-evolves and which selection acts upon. This point of view is increasingly a part of biology, in conjunction with something which I do not think those Worthy Ancestors anticipated, viz., development processes themselves acting as constraints on evolution...

Things to learn more about: Conservation of genes important in development, e.g. hox. Conservation of body plans, and whether this is any more than a statistical artifact. (I remember reading that argument from G. C. Williams sometime in the 1990s, but cannot now recover where.)
