I’m not sure why I started thinking about it (I think it has something to do with parental care in dinosaurs), but I wonder how precocial and altricial development patterns in different animals evolved. I’m sure other people have thought about it before, but I do wonder about the interplay between behavior and development, especially the physiology of altricial young that cannot care for themselves. I would imagine that parental care as a behavior would develop first, but given that, how did this influence the physiology and development of offspring? If I find any answers, you can bet I’ll write about it.
