Thumbs, toes, and tears: and other traits that make us human

Toes: the curious tale of the hallux magnus

Standing up: sex and the single hominid - Thumbs: mothers of invention

Homo hallucinatory, the dream anima

Making thoughts out of thin air

I am me: the rise of consciousness

words, grooming, and the opposite sex - Laughter: Howls, hoots, and calls

The creature that weeps

The language of lips
