- The authors have proposed that the specialization of the brain’s two hemispheres was already in place when vertebrates arose 500 million years ago.
- The left hemisphere originally seems to have focused in general on controlling well-established patterns of behavior; the right specialized in detecting and responding to unexpected stimuli.
- Both speech and right-handedness may have evolved from a specialization for the control of routine behavior.
- Face recognition and the processing of spatial relations may trace their heritage to a need to sense predators quickly.

Once again, science gives us even more evidence that the belief in the supernatural is purely a neurological phenomenon. The study was published in the Proceedings of the National Academy of Sciences, and the researchers have found the parts of the brain where many religious thoughts or experiences take place. They also found that these brain patterns were similar to when people thought about people they have never met, such as historical figures and movie stars.
The evidence seems to be coming in every day confirming that we are purely natural creatures, and I love it!
