Man-made geographical high points in southern England and Wales have been observed for centuries, including earthworks, stone monuments like Stonehenge, and hill camps. But something quite unexpected about their distribution may have been verified.

Evolutionary science repeatedly declares that chimps and humans are 98 percent genetically identical, which is then taken as solid evidence that mankind evolved from an apelike ancestor. But a former BBC producer’s new book has found reasons to emphasize research that is often overlooked by evolutionary advocates—scientific results that reveal the uniqueness of man.

Evolutionary history holds that the first humans emerged about 200,000 years ago.

Portions of a primate’s fossilized face and jaw were recovered near Barcelona in 2004.
