Here's the map that shows where the epicenter was - quite close to our house!

We imagine eureka moments taking place in modern laboratories or classical civilizations. But key insights of biology, pharmacology, genetics, and navigation arose and persisted solely by word of mouth, in small, unwritten tongues. Finally, this web of knowledge contains feats of human ingenuity -epics, myths, rituals - that celebrate and interpret our existence.
Pundits argue that linguistic differences are little more than random drift, minor variations in meaning and pronunciation that emerge over time (the British say 'lorry', Americans 'truck'; Tuesday is CHEWS-day, for Brits, TOOZ-day for Americans).
These reveal nothing interestingly different about our souls or minds, some claim. But that's like saying that the Pyramid of Cheops differs from Notre Dame Cathedral only by stone-cutting techniques that evolved randomly in different times and places; revealing nothing unique in the ancient Egyptian or Medieval French imagination.
All cultures encode their genius in verbal monuments, while considerably fewer do so in stone edifices. We might as well proclaim human history banal, and human genius of no value to our survival.
The fate of languages is interlinked with that of species, as they undergo parallel extinctions. Scientific knowledge is comparable for both domains, with an estimated 80% of plant and animal species unknown to science, and 80% of languages yet to be documented.
