The increase in human body size did not occur gradually throughout human evolution. At least, it was not always so. The big leap occurred between 2 and 2.5 million years ago and was starred by two human species, the robust Homo rudolfensis and the great explorer Homo erectus , according to a new research carried out by a team from the universities of Reading and Oxford. Homo erectus , known for its incursions outside Africa, was the first homini…
Human Ancestors Suddenly Got Bigger Around 2 Million Years Ago — With Average Body Size Jumping From 88 to 132 Pounds
Learn how fossils show human ancestors did not grow bigger in a straight line, but split into larger and smaller evolutionary paths.
Early humans did not gradually become larger. Their size increased relatively late when the way of life changed significantly
Why Human Body Size Leaped 2 Million Years Ago
Human body size evolution was not a linear progression. Instead, a massive body mass explosion occurred 2 to 2.5 million years ago with Homo erectus, while divergent species like Homo floresiensis maintained a smaller, child-sized stature.
