Developmental differences in visceral morphology of megophryine pelobatid tadpoles in relation to their body form and mode of life.

Neurological and developmental differences lead to directional selection and changes in the set of foraging behaviors between generations of honey bees.

When familiarity and meaningfulness of material were equated across age, developmental differences in memory performance was no longer a factor.

This mammalian characteristic suggests that, although mammals are genetically similar, dramatic changes in regulatory genes caused distinct developmental differences.
