For example, intelligence can be defined as an individual capacity to learn, recognize problems, and solve problems. ...
Animal experiments have been invaluable in elucidating basic physiological mechanisms of sound encoding, auditory learning, and pattern classification in the mammalian brain. The human auditory nerve contains about 30,000 such nerve fibers, each capable of firing anywhere between zero and several hundred...
How does an animal's brain affect its intelligence and learning? How does adaptation affect the diversity of an ecosystem? How does weather affect animals behavior? How do endangered species affect humans? How do species extinction affect classification? How can an invasive species affect an ecosyst...
* The current theory of evolution does not predict how this could happen. One line of current research is looking at the effect of very small changes in DNA patterns during embryonic development. Any new animal, be it a mouse or a human, starts life as a single cell. That cell ...
the bushmeat trade. The latter is particularly alarming: logging has driven roadways into the forests that are now used to ship wild-animal meat-including chimpanzee meat-to consumers as far afield as Europe. Such destruction threatens not only the animals themselves but also a host of fascinati...
