main evolutionary mechanism by “Triadic Niche Construction”, an interactive expansion of ecological,
neural, and cognitive niches. The latter seems to have been triggered by the use and manufacture of tools,
which led cognitive capacities to exceed the threshold for the emergence of language and self-consciousness
