The time of “Lucy.”

Lucy lived at a time chimps and homo recently diverged from their common ancestor.

Even Lucy and her kind used stone tools, they worked, changed their stone tools. Chimpanzees today refuse to learn this.

The brain of Lucy was likely just a tad larger than the brain of chimpanzees. This caused problems when giving birth.

After Lucy came Homo habilis and then Home Erectus, smaller jaws and bigger brains,

Fascinating!

There is a cave in South Africa, the Sterkfontein caves, containing lots of early humanoid fossils but they have been very difficult to date for various reasons.


Quote:

. . .they are actually between 3.4 and 3.6 million years old, a study estimates. The revised dates, published in PNAS on Monday (June 27), would mean they’re older than the famous Lucy fossil unearthed in Ethiopia, which is dated to around 3.2 million years ago. . .

So the evolution of our distant ancestors is more complex than was thought.

Those days were utopia for conservatives :D :D

Primatologist and anthropologist Jane Goodall discovered that the Gombe
National Park chimpanzees used objects—stems, twigs, branches, leaves,
and rocks—in nine different ways to accomplish tasks associated with feeding,
drinking, cleaning themselves, investigating out-of-reach objects, and as
weapons, flailing branches and throwing rocks as missiles. In communities
outside Gombe, chimpanzees use objects for different purposes. These
behaviours, passed from one generation to the next through observational
learning, can be regarded as primitive cultures.

They do not work the rocks tho, that is the difference with Lucy and succeeding homo variants.
