No primate species have gone extinct within the last century, but now 25 species of apes, monkeys, lemurs, and other primates are in danger of disappearing soon, according to a new report issued by Conservation International. The two main causes of primate decline are the destruction of tropical habitat and hunting by locals; other threats include the live capture of primates for the pet trade and biomedical research. Speaking of endangered mammals, Spanish authorities are weighing the possibility of cloning a Spanish mountain goat after the last known survivor of the rare species was found dead last week.
