An international study, published in the Journal of the American Academy of Sciences and led by the US Alliance for Wildlife at the San Diego Zoo, explained how climate change and deforestation interfere with the way of life of monkeys, prompting them to get off the ground.
The researchers researched the beauty of 150,000 hours of observation of 47 species of monkeys and lemurs, in 68 different sites in the Americas and Madagascar.
Research shows how temperature and forest degradation push monkeys to the ground.
The results also indicate that only populations that have a more diverse diet and live in large groups can adapt more easily to a terrestrial lifestyle. The researchers explained: "Our findings suggest that human presence, often a threat to primate conservation, may interfere with their natural adaptability to global change." Lemurs are seen as ancestors of more evolved primates: however, although they show morphological and behavioral similarities with primitive primates, lemurs descend from them just like other currently living primates.
It is therefore incorrect to think that lemurs are ancestors of apes or any other primate. The ancestors of present-day lemurs began to diverge from other primates between 62 and 65 million years ago. Around 40-52 million years ago, they reached Madagascar, probably through trunks and masses of floating vegetation that allowed them to cross the sea arms that separated the island from the mainland, although the possibility of their presence has not been excluded.
of an isthmus or a series of small islands reachable by swimming that connected the two masses of land. As there was no great interspecific competition, lemurs could occupy numerous vacant ecological niches and evolve in complete isolation, differentiating in a multitude of shapes and sizes.
Most of them, however, have arboreal and nocturnal habits and feed mainly on fruit and insects: to limit competition for food in areas where the ranges of several species overlap, despite the extreme similarity between the diets of the various species, each of them specializes in feeding on a certain food.
