Many biologists believe that handedness is related to brain structure, say, for example, early right-handers may have been better at language. The model predicts that today everyone has genes which confer a basic predisposition of 78% to be right-handed. How children actually turn out, however...

The Thunderbird is one of the most readily recognized creatures of American Indian mythology.While the vast majority of biologists believe the Thunderbird myth to be nothing more than a spiritual symbol,some zoologists believe that the hard may actually exist.I still vividly recall seeing an ...
In the past 50 years there has been a great increase in the amount of research being done on the brain. Chemists and biologists have found that the way the brain works is far more complicated that they had thought. In fact many people believe that we are only now really starting to ...
Native toAsiaandAfrica, thepeacockis bound to be on a list of the world’s most beautiful animals. Its jewel-like coloration and the male’s stupendous train are unignorable. But again, the peacock didn’t evolve to please humans. Some biologists believe that the train, made of long-tail...
s a self-organizing engine for the origin of a selective force. And that selective force can be completely arbitrary from natural selection. The math has supported that for a very long time, but evolutionary biologists are still resistant to it, mostly because many of them grew up reading ...

Here are some of the species with populations that have rebounded: Bald eagle The fate of the United States' national bird, the bald eagle, used to be dire, with populations dipping as low as 470 pairs, John White said. Now, biologists believe there are up to 300,000 bald eagles ...
For the better part of a century, most biologists have been reluctant to use those words, mindful of a principle of evolution that says "evolution cannot run backwards". 在大半个世纪里,大多数生物学家都不愿使用这些词,因为他们牢记着一条进化论的原则,即“进化不能倒退”。 Even those artists ...
