Human Biology

The groundbreaking New York Times bestseller is now adapted for young adults! This is the 200-million-year story of how the female body gave rise to the human species and forever shaped life on Earth and what that means for us in the future.

As human beings, we are fascinated by what makes us tick. We know that nature gave us certain biological appetites to ensure our survival, among those the need for water, food, sex, and love, but meeting these alone is not enough to ensure happiness. Scientists, and now managers, are realizing that people have a biological need to experience social rewards like praise, the thrill of innovation, and the satisfaction of acquiring new skills.

In Unfit for Purpose, biologist and broadcaster Adam Hart explores the mismatch between our fundamental biology and the modern world we have created. In each chapter Adam reveals the many ways in which biological adaptations that evolved to help us survive and thrive now work against us. For example, in the modern world stress is a killer, but how did 'fight or flight' instincts turn from life-savers to life-takers? Obesity might be a disease now, but is it really just a troublesome side-effect of our complex evolutionary past?

This is a short section from the book Fascinating Facts You'll Love to Share, focusing just on human body facts. We are often more interested in what we see, and there is no doubt that the world is filled with wonders! There's a lot to amaze at, from the atomic building blocks of life to the farthest reaches of space. The human body is another wonder that should be added to the list!

A fun way to expand your knowledge with facts about the human body.

Do your eyes send out light like headlights? Does your liver create blood? Do bumps on your head tell what's inside your brain? At one time science supported wild notions like these! But later studies proved these ideas were nonsense. Discover science's biggest mistakes and oddest assumptions about the human body, and see how scientific thought changed over time.
