Rivers create species. Now, scientists have discovered a new primate that also appears to follow this rule, blocked off from his cousins by a confluence of rivers in the Peruvian Amazon.
Noncompliance with laws and urbanization cause deaths, say environmentalists. Species is found in three cities; at least 10 die each year.
Deforestation, real estate pressure and uncontrolled growth of Manaus have reduced the population of the primate that is endemic to the Amazon capital.
