Early hominids, such as the australopithecines who had more apelike brains and skulls, are less often thought of or referred to as "human" than hominids of the genus Homo some of whom used fire, occupied much of Eurasia, and gave rise to anatomically modern Homo sapiens in Africa about 200,000 years ago where they began to exhibit evidence of behavioral modernity around 50,000 years ago and migrated out in successive waves to occupy all but the smallest, driest, and coldest lands; and permanently manned bases in Antarctica, on offshore platforms, and orbiting the Earth. The spread of humans and their large and increasing population has had a destructive impact on large areas of the environment and millions of native species worldwide.
