As an illustration of the extraordinary plasticity of our species, we examine the story of Zana, whose genetics, described in a 2021 paper, establish her as a member of a modern human population. Zana, who was captured living wild in the Caucasus Mountains in the 19th century and held in captivity for forty years, was two meters tall, covered in hair, superhumanly strong, lacked speech, slept naked outside all winter, could crush bones with her teeth, swam in rivers during their full spring flood, and could outrun a horse. She was described by the many locals who were familiar with her as an Almasty, or Sasquatch. Building on early biological descriptions of two species of human and the contemporary evidence on feral children, we postulate that our own developmentally delayed, self-domesticated form of humanity has—as is the case among other species for whom developmental change has been central to their evolution—a developmentally accelerated, wild form, induced by a lack of care in early development, and that reproducing populations of such individuals are what we know as Sasquatch.
