Retrovirus struck ancestors of chimpanzees and gorillas millions of years ago, but did not affect ancestral humans

The ancestors of chimpanzees and gorillas were infected with a deadly retrovirus about three to four million years ago, but there is no evidence it infected ancestors of modern-day humans, according to research by genome scientists. The virus struck after humans had split off the evolutionar...

Chimp genome reveals a retroviral invasion

...al infection. Eichler and colleagues estimate that gorillas and chimps were infected about 3 -- 4 million years ago, and baboon and macaque about 1.5 million years ago. The disconnect between the evolutionary history of the retrovirus and the primates, the authors conclude, could be explained if the Old World...

Ebola virus: from wildlife to dogs

...known, but from infected carcasses of chimpanzees, gorillas and certain forest antelopes. Results have come from work conducted over the past several years by IRD scientists and their partners (1) to shed light on the virus's propagation paths. The discovery of Ebola virus antibodies in several species of non...

Protecting endangered species helps reduce poverty

Saving endangered species like pandas, gorillas and tigers helps reduce poverty and improve the lives of local communities, according to a new World Wildlife Fund report.

Uganda's mountain gorillas increase in number

The most recent census of mountain gorillas in Uganda’s Bwindi Impenetrable National Park—one of only two places in the world where the rare gorillas exist—has found that the population has increased by 6 percent since the last census in 2002, accord...

Gene study shows three distinct groups of chimpanzees

... we know so little about them, and even less about gorillas and orangutans." The chimpanzee genome differs from the bonobo genome by about 0.3 percent, which is one-fourth the distance between humans and chimps. Yet chimps and bonobos have radically different social systems, cultures, diets and mating sy...

Our theory is that this is because humans had this innate viral defense system," Emerman said. To test their hypothesis, Emerman and co-authors Harmit Singh Mal...
