We are what we ate
Article Abstract:
The conventional wisdom of evolution has been challenged by O'Connell and colleagues, by suggesting that changes that led to the evolution of modern humans were initiated by systematic exploitation of subterranean food sources, and the recruitment of grandmothers. This comes from observations made in a study of the Hadza population living around Lake Eyasi in northern Tanzania, who still practise traditional foraging. Post-menopausal grandmothers were found to use foraged tubers to support both themselves and the children of their daughters, releasing the daughters to become pregnant again.

The oldest whodunnit in the world
Article Abstract:
Evidence exists of a link between the hominid group Paranthropus and stone tool manufacture between around 2.5 and 1.5 million years ago. There is data showing that Paranthropus aethiopicus/boisei existed in Ethiopia's Omo region during the same approximate time period. These relate to new evidence from Gona in Ethiopia, which reveals that the onset of tool manufacture dates back to 2.5 million years ago and a recent report that stone tools were discovered in 'close association' with a jawbone from an early example of the Homo species at a nearby 2.3 million-year-old site in Hadar.

A precious little bundle
Article Abstract:
The 3.3 million-year-old skeleton of a three-year-old Australopithecus afarensis female, found in Dikika, Ethiopia, serves as an outstanding source of information about a crucial stage in human evolutionary history. A description of the fossil and its palaentological context are presented.
