Distribution and Habitat
Before their extinction, adapiform primates were primarily found across North America, Asia, and Europe, with a few species in Africa. They flourished during the Eocene when those regions were more tropical in nature, and they disappeared when the climate became cooler and drier. Today, the lemuriforms are confined in the tropics, ranging between 28° S to 26° N latitude. Lorises are found both in equatorial Africa and Southeast Asia, while the galagos are limited to the forests and woodlands of sub-Saharan Africa. Lemurs are endemic to Madagascar, although much of their diversity and habitat has been lost due to recent human activity.
As with nearly all primates, strepsirrhines typically reside in tropical rainforests. These habitats allow strepsirrhines and other primates to evolve diverse communities of sympatric species. In the eastern rainforests of Madagascar, as many as 11 or 12 species share the same forests, and prior to human arrival, some forests had nearly double that diversity. Several species of lemur are found in drier, seasonal forests, including the spiny forest on the southern tip of the island, although the lemur communities in these regions are not as rich.

Famous quotes containing the words distribution and/or habitat:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
