Prehistory (250000 - 10000 B.C.E.)

Neanderthals create world’s first string

A fragment of string discovered at a Neanderthal rock shelter in southeastern France — dating between 41,000 and 52,000 years ago — is the oldest known direct evidence of fiber technology in human history. Its construction reveals that Neanderthals understood tree seasonality, planned across multiple steps, and grasped basic numerical concepts, upending long-held assumptions about their cognitive abilities.

Tally marks

Human invent tally marks, their first numeral systems

Around 43,000 years ago, early humans carved the first tally marks into bone, inventing the earliest known numeral systems. This brilliant shift toward abstract mathematics allowed our ancestors to track lunar cycles and inventory resources. It laid the vital groundwork for modern mathematics, commerce, and advanced human societal planning.
