(Up to about 15,000 years ago, large parts of North America and Europe were under ice cover.) The world population may have reached 1.5 million during this period, most of it in Africa and Asia. Hypothetically, the maximum population of Homo sapiens was about 800,000 in the Afro-Asian territory, while the corresponding numbers for Neanderthal man and Java man may have been 250,000 and 100,000.įrom around the onset of the last Ice Age, some 70,000 years ago, Homo sapiens were ascendant and in the subsequent millennia spread over continental territories theretofore unoccupied by man: Australia, Siberia, and eventually the Americas. Later, three branches of humanity emerged: Homo sapiens in Africa and south Asia, Homoneanderthalensis (Neanderthal man) in Europe, and Java man in Indonesia. The population size of Homo erectus over the entire earth may have varied between 500,000 and 700,000. The extent of the territory occupied and variations in climate thus appear more influential than technical progress. The resulting estimates indicate small populations, despite technical advances such as the domestication of fire. The most commonly used method assigns to a given territory the population density among peoples with similar culture and who are living under similar climatic conditions, observed in some recent period.

In the twenty-first century, numerous methods are available for making estimates about prehistoric populations. Homo habilis thus yielded its place to Homo ergaster, which, having quadrupled the territory it occupied in Africa, spread to Europe and to southern Asia, taking on the closely similar form of Homo erectus. In successive stages of evolution, the great selective advantage that resulted gave humans the ability to eliminate their nearest competitors. According to an estimate by János Nemeskéri, there may have been a population as great as 100,000, already exhibiting subgroups with distinct physical features.įrom then onward, human genetic change has been very rapid: Most notably brain size, which at the start was less than 500 grams, increased by more than 1 kilogram in less than 3 million years.

The territory occupied by these early humans covered some 4 million square kilometers (about 1.5 millon square miles) of wooded savanna-land between today's Ethiopia and Zimbabwe. Its distinguishing characteristics were that it made, and more or less systematically used, tools of wood or flint stone, and that it exhibited a novel, more advanced type of social behavior: It consumed food not where it was obtained but at the group's campsites. Possibly as long as 3 million years ago, Homo habilis emerged in East Africa. Humanity's dominance of the planet and its exploitation of the Earth's resources have been accompanied by major increases in the size of human populations.
