End of the Hadean Eon and the beginning of the Archaean Eon.2.5 billion years ago: End of the Archaean Eon and beginning of the Protoerozoic Eon. 1.8 to 2.1 billion years ago: First known eukaryotes (organism whose cells contain complex structures enclosed within membranes).A large number of stone tools have been found in sediment deposits in northern China.More than 400 fragments have been found in a stratum of sediment thought to have formed 15 million years ago.

: Maybe 2.5 to maybe 6 million years ago, or somewhere in the middle, something happened and a few hominids started walking upright and thinking a little different then their progenitors, thus starting our rise to pre-dominance of the earth.

It is quite large being around 24 cm long, 13 cm wide, and 3 cm think, and would have been “re-touched” using a soft hammer percussion flaking tool made of either antler, bone, ivory or wood (so-called ).

Here are a few pointers to interesting news items and resources concerning life in the Stone Age: Oldest tools A stone-age weapons industry Wonderwerk Cave & Fire Cooking Stonehenge Marden Henge Monolith in the Sicilian Channel Domestication Domestication of the dog Domestication of the horse Domestication of cattle Domesticated wheat “Halls of the Dead” in the UK The Temple Period in Malta Plakias in Crete Cyprus Alepotrypa Cave Turkey China Archaeothanatology Wine & Beer The First Carpenters Oldest tools Experts have dated the oldest stone hand axes, found in Ethiopia, to ca. This technology has been linked to the appearance of Home erectus around 1.8 million years ago. rock flakes) have been dated to 2.6 million years ago.

Also it has been suggested that the genus Homo evolved his brain cortex and upper limbs as he adapted to the new bio-mechanical functions imposed by these first tools.
