Primates on the brink

... America, showing that threats to monkeys, lemurs, great apes and other non-human primates exist wherever they live. All 25 primates on the 2004-2006 list are found in the world's biodiversity hotspots-34 regions identified by Conservation International that cover just 2.3 percent of the Earth's land surf...

Scientists analyze chromosomes 2 and 4

...r than chimpanzees, gorillas, orangutans and other great apes. For more than two decades, researchers have thought human chromosome 2 was produced as the result of the fusion of two mid-sized ape chromosomes and a Seattle group located the fusion site in 2002. In the latest analysis, researchers searched ...
