摘要
Today, humans inhabit most of the world's terrestrial habitats. This observation has been explained by the fact that we possess a secondary inheritance mechanism, culture, in addition to a 遺傳 system. Because it is assumed that 文化 演化 occurs faster than 生物 演化, humans can adapt to new ecosystems more rapidly than other animals. This assumption, however, has never been tested empirically. Here, I compare rates of change in human technologies to rates of change in animal morphologies. I find that rates of 文化 演化 are inversely correlated with the time interval over which they are measured, which is similar to what is known for 生物 rates. This correlation explains why the pace of 文化 演化 appears faster when measured over recent time periods, where time intervals are often shorter. Controlling for the
