Resumen de Life in the sloth lane
George-Louis Leclerc, the Comte De Buffon, was the most famous naturalist on the planet in the middle of the 18th century, and he didn't think much of the New World. He proclaimed the Americas degenerate, a sodden, miserable land filled with weak and inferior species. But Buffon reserved his most biting contempt for one creature in particular. He wrote of their too short and badly terminated legs, of their slowness, stupidity and even habitual sadness. These sloths, he continued, are the lowest term of existence in the order of animals with flesh and blood. One more defect would have made their existence impossible. Part of the reason sloths are such extreme energy savers is their diet. They are arboreal folivores, meaning they live in trees and eat leaves. Sloths have adopted a different strategy: they nibble a bit here and there, making sure to keep their stomachs full. And they don't rush digestion.
