I'm talking about flies in population cages. Real-time morphogenesis, if you will, where we perturb a developmental system and watch what happens. The general result of the growth of developmental intertia has been to make the biosphere, as a whole, less amenable to change. Because that makes common descent look pretty iffy. And everybody knows common descent is true.
Offspring have the cleavage patterns their parents had.
