Brain development does not occur uniformly across the brain, but follows a newly identified developmental sequence, according to a new Penn Medicine study. Brain regions that support cognitive, social ...

The multiple skeletal components of the skull originate asynchronously and their developmental schedule varies across amniotes. Here we present the embryonic ossification sequence of 134 species, ...

The goal of this article is primarily conceptual in nature in that it attempts to offer a novel way to employ developmental sequence data in order to decide between UG-based (e.g., Felix, 1985; White, ...

Amidst the hoopla over the exact number of genes we have in our genome—more than a fruitfly, fewer than a rice plant—a more fundamental genetic truth has often been obscured. The expression of ...

2 issues central to the construct validity of Kohlberg's organismic 6-stage model of moral judgment development are empirically assessed: (a) stepwise, invariant sequence and (b) irreversibility of ...
