Famous Scientists

About 2.3 million years ago our very earliest ancestors invented their first primitive tool, the split stone, which they used for cutting and scraping. For the next 1 million years early humans gradually learned to customize stone tools and use fire.
Modern humans first appeared about 200,000 years ago. About 50,000 years ago they (or should that be we?) began to use language, symbols and more complex tools.
As inventions and discoveries added to one another, human civilization, technology and science advanced and evolved. The word “science” is derived from the Latin word “scientia” which means “knowledge.” Science is probably the most important and helpful area of study for the human race.
