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.

After 100 years, automobiles still need engine oil, transmission fluid, brake fluid, antifreeze, power-steering fluid, and so on. Wouldn't it be great if just a single multipurpose fluid could be circulated from a central reservoir? Each part would use only the needed properties of the fluid, exclude detrimental properties, and then send it back.

Evolutionary history holds that the first humans emerged about 200,000 years ago. It was thought that these early people were in some ways sub-human, as the gradual development of higher-level thinking slowly separated them from their ape-like ancestors. But the archaeological find of an ancient crafted hand tool makes that assumption quite questionable.

Most people north of the equator have an observable suntan by August. Ironically, a desire to be outside is often coupled with another strong desire to get out of the sun, as indicated by sales of sun umbrellas and other types of sunshades.

A key design feature shared by many 100-year-old barns and some modern skyscrapers is that the external shell carries the building's load with a minimal use of internal columns for support. Internal floors and walls, if any, function in a structural way to stiffen the building.
