Document Summary
Domestification of animals and plants as well as use of stone and metal to create energy: start of the agricultural revolution. Times passed and then we began to develop machines and extract energy from coal, crude oil and natural gas: this was the beginning of the industrial revolution. Homo erectus possessed tools and that these tools were perfect in many ways: they were simple, portable, efficient and utilitarian. Homo sapiens evolved with brains about 50% larger than the homo erectus. We migrated to a variety of lands characterised by a range of climates. We do not have clear evidence if a continuous corridor existed or if it was occupied by sufficient wildlife for food. Regardless, it is estimated that most of north and south american was occupied in about 2000 years: tools. Figured out how to use tools 2 to 3 million years ago (though some might argue, the domination began with our learning to walk on two legs).
