Smith believes that the hunters were well aware of the more disciplined ways in which their prey behaved. ■ Instead of following the cattle on their annual migrations, the hunters began to prevent the herd from moving from one spot to another. ■ At first, they controlled the movement of the herd while ensuring continuance of their meat diet. ■ But soon they also gained genetic control of the animals, which led to rapid physical changes in the herd. ■South Africa farmers who maintain herds of wild eland (large African antelopes with short, twisted horns) report that the offspring soon diminish in size, unless wild bulls are introduced constantly from outside. The same effects of inbreeding may have occurred in controlled cattle populations, with some additional, and perhaps unrecognized, advantages. The newly domesticated animals behaved better, were easier to control, and may have enjoyed a higher birth rate, which in turn yielded greater milk supplies. We know from rock paintings deep in the Sahara that the herders were soon selecting breeding animals to produce offspring with different horn shapes and hide colors.

■Only rarely can we derive any “real” quantities from deposits of broken pots. ■However, there is one exceptional dump, which does represent a very large part of the site’s total history of consumption and for which an estimate of quantity has been produced. ■On the left bank of the Tiber River in Rome, by one of the river ports of the ancient city, is a substantial hill some 50 meters high called Monte Testaccio. ■ It is made up entirely of broke oil amphorae,mainly of the second and third centuries A.D. It has been estimated that Monte Testaccil contains the remains of some 53 million amphorae, in which aroud 6,000 million liters of oil were imported into the city from overseas. Imports into imperial Rome were supported by the full might of the state and were therefore quite exceptional—but the size of the operations at Monte Testaccil, and the productivity and complexity that lay behind them, nonetheless cannot fail to impress. This was a society with similarities to modern ones—moving good s on a gigantic scale, manufacturing high-quality containers to do so, and occasionally, as here, even discarding them on delivery.

Competition may occur for any needed resource. ■ In the case of animals it is usually food; in the case of forest plants it may be light; in the case of substrate inhabitants it may be space, as in many shallow-water bottom-dwelling marine organisms. ■ Indeed, it may be for any of the factors, physical as well as biotic, that are essential for organisms. ■ Competition is usually the more sever the denser the population. ■ Together with predation, it is the most important density-dependent factor in regulating population growth.
