The Human Body in 1,000 Years

Evolution has changed our bodies and faces over thousands of years—and it's still happening. Here's how leading anatomical experts predict our [#highlight2]descendants[/highlight2] will differ physically from us in 1,000 years from now.

We’ll be taller at 6-7ft because of improved nutrition and medical science. Osteopath Garry Trainer says:“The average American is about one inch taller than 1960." Our intestines will get shorter so we don't absorbas much fat and sugar—a natural way of avoiding obesity, says dentist Dr. Philip Stemmer.

We’ll have smaller brains, maybe because so much memorizing and thinking is done by our computers.“Science fiction images show humans of the future with big brains, but big brains are not necessarily the best." says Chris Stringer, from the Natural History Museum. There will be large eyes to compensate for smaller mouths. Gary Cooper, of Lancaster University, explains: “Communication will rely on facial expression and eye movements.”

Dentist Doctor Stemmer also thinks there could be fewer teeth as softer food needs less chewing and biting. He says: "We could even get our nutrition from liquids or pills in the future, which could mean less teeth and receded jaws.”
