Document Summary
All major habitable land masses were colonized by 12,000-15,000 ybp. Early americas had mass extinctions of prey species due to human immigration. At the dawn of the neolithic revolution, ~10,000 years ago, the global population was 1- 10 million: at 0 ce (common era, which began 2000 years ago, like bc), the population was. In 2012 we passed the 7 billion mark. Rapid human population growth is the most important event since the last major glaciation in term of impact on our biosphere. human growth rate is roughly exponential. So the population is doubling every few years. Cultural evolution and changes in carrying capacity for the human population (exam) Cultural evolution (or socio-cultural evolution) is a cumulative progression of adaptive discoveries of increasingly sophisticated tools and social systems. It allows people to learn from the experience and improvements of others, and to pass useful information from one generation to the next; it is also a social equivalent of natural selection.
