Human speech requires precisely organized body parts and biochemicals that are certainly complicated enough on their own to have warranted their special creation. But a new study indicates that gestures also play a key role in interpersonal interactions.

David Queller and Joan Strassmann, evolutionary biologists at Rice University, recently proposed a new way to describe what makes an organism a unified whole. They defined an organism as an entity made up of parts that cooperate well for an overall purpose, and do so with minimal conflict. But how do parts like these get together, and where does purposeful behavior come from?

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.
