This Posthuman has underwent an evolutionary pathway resulting in a superficial resemblance to its reptilian ancestors from the Paleozoic era. The soft cartilage on its nose and ears has greatly reduced in development. Its hair has fused and hardened into scale-like structures, not too different than the ones on armadillos or pangolins. It's legs no walk in a sprawling gate, and its tailbone has extended into a stiff, but external structure. Its metabolism has slowed down tremendously, resulting in the genitals of males being held internally. It's dentition have reverted back to a a singular row of homogenous needles. Offspring can be weened off milk in a matter of weeks, if not days. Saving the mother from a huge metabolic burden.
