April 12, 2006 The doting mom of a wormlike amphibian found in Africa lets her babies devour her own flesh, scientists have found. The tropical creature transforms its skin into a nourishing, fat-rich meal for its newborns to eat, researchers say. This bizarre form of parental care was uncovered in Kenya ( map ), where a team of biologists observed the young of a caecilian, a type of limbless amphibian, feasting on their mother. Furthermore, the youngsters' teeth appear to be specially designed for eating their mother's flesh.
What's in a Howl? by Fred H. Harrington Professor of Ethology Mount Saint Vincent University, Nova Scotia Ask anyone about wolf vocalizations and the howl invariably springs to mind. Even though wolves bark, woof, whine, whimper, yelp, growl, snarl and moan a lot more often than they howl, it is howling that defines the wolf, and fascinates us.
Do wolves attack people? Answer: In the past 100 years, there have been only two incidents in North America, in 2005 and 2010, where wolves have allegedly killed a human being. In comparison to deaths caused by other large carnivores, this is an extremely rare rate of occurrence.
Louis M. Herman Kewalo Basin Marine Mammal Laboratory, University of Hawaii and The Dolphin Institute, Honolulu, Hawaii Human language and ape language No single trait has been linked more closely with the human species than has language. However, the definition of language and its uniqueness as a human trait continue to be areas of study and debate. Some, such as the linguist Noam Chomsky, take an evolutionary discontinuity position professing that language is a highly nunique adaptation supported by special modifications of the brain that appear only in humans.

Bears are among nature’s most majestic creatures, and seeing one in the wild is an unforgettable experience. Get too close, however, and your encounter with a bear can be more terrifying than awe-inspiring. Fortunately, despite humans’ continued encroachment into “bear country," attacks on people are rare, and fatalities are even rarer. Still, bears are immense, powerful wild animals, and any meeting between bears and humans can potentially turn deadly.
Pigeons have featured in numerous experiments in comparative psychology , including experiments concerned with animal cognition , and as a result we have considerable knowledge of pigeon intelligence . Available data show, for example, that: Pigeons have the capacity to share attention between different dimensions of a stimulus, but (like humans and other animals) their performance with multiple dimensions is worse than with a single stimulus dimension.
