Mammals must undergo a transformation phase, called youth, between the neonate and the adult. This youthful metamorphic and meta-behavioral phase is necessary while the mammal is remodeling from sucking milk to munching grass or hunting meat. During its youthful phase a mammal is not simply growing linearly into its adult form and behavior but is …
