Scientists find 60,000-year-old ostrich eggshell carvings follow precise geometric rules, revealing early humans carefully planned designs.

“The results demonstrate that Homo sapiens during the late [Middle Stone Age] mastered precise, pre-planned patterns anchored in specific geometric affordances: orthogonality [meaning the use of right ...

Crows can recognize geometric patterns, suggesting that humans aren't unique in understanding shape structure.

The paper, published recently in PLOS One, describes an investigation of 112 ostrich eggshell fragments dating back more than ...

A member of the now-extinct hominid species Homo erectus engraved a geometric design on a sea shell nearly half a million years ago, long before the earliest evidence of comparable etchings made by ...
