Assessment of Alternatives in Mineral Resource Technology

The earliest caveman, very much a minority group, in the face of great adversity and person- al peril, had to take his livelihood by stealth or force of arms - aided by some degree of reas- on and ingenuity. He was pretty much a law unto himself. As time went on, his type became more numerous; and, after bumping heads with the- tough bloke who lived in the cave across the valley, he decided that perhaps he ought to try to get along with him. Perhaps he could trade some over-ripe emu meat for that `roo skin that he had tried to take. Then too, next time he wants a woman, he had better use a lighter club and just stun her a little - that last one was pretty badly bashed. Perhaps he should keep her around the cave and train her to keep the fire going, gather some roots, and skin the game. Those joeys of hers are kind of cute too. Of course they eat, and it would necessitate bringing in more food. So man gained increasing responsib- ilities to his family and neighbours. He domesticated animals, learned that he could cultivate certain plants that were palat- able and would supplement the meat diet, and found that he could modify earth materials to make tools - he became a grazier, a farmer, a miner and a manufacturer. He ceased to be nom- adic and community life came into being. This complicated life and made more rules essential.
