In the evolution of humans, genetics show a bottleneck about 75000 years ago. Some catastrophic global event, probably a volcanic eruption, nearly wiped out all the hominids that were ancestors of Homo sapiens, in Africa. The best evidence suggests the only bands that survived the event clung to life in the east African coast near the southern end of the continent. They seem to have subsisted on shell fish and other crustaceans collected during the low tide. There are some telltale marks of intelligence about that band. Scratches on stone tools that could be decorations or ownership marks, shells with holes punched through them to make garlands of shells, using fire to sharpen and temper their stone tools etc.
In hardly 30,000 years they expanded all across Africa, broke out of Africa, set up nascent populations all across Arabia, Persia, India, Andaman Nicobar Islands (this is important), Malaysia, Java, Sumatra, Papua New Guinea and reached Australia.
Andaman islands is important because the first clade in the cladogram of world languages is Andamanese and Non-Andamanese. It is very clear to me, as a layman, not a strict scientist, the Great Leap Forward that happened 75000 years ago in our history was the development of abstract language and the ability to exploit coastal resources.
So yeah, tide prediction changed our history. But not 75 years ago in Europe, but 75000 years ago in South Eastern Africa.
