Discover everything you need to know about biology, with the simplest most visual guide to the science of life.

How do vaccines work? What is special about stem cells? How did we evolve from bacteria? The science of life can be dauntingly complex, and it can be hard to separate "good" science from "bad", fundamental truths from the much-hyped breakthroughs reported in the media.

With clear, easy-to-understand graphics and packed with fascinating facts, How Biology Works demystifies both the core biology that may have eluded us at school, and the cutting-edge life science that makes the news, answering the questions that spark our curiosity.

With power to every page, this striking science book:

- Is illustrated entirely by specially commissioned, boldly-colored, distinctive, flat, vector graphics that explain each topic clearly and engagingly.
- Uses clear, distinctive, eye-catching graphics to make even complex biology easy to understand.
- Offers a practical, no-nonsense approach to each subject.

Building from life's fundamental ingredients, such as carbon and water, the book explains chemical processes in living cells, controlled by the ultimate biochemical, DNA. It shows how DNA is made of units called genes, which are shuffled in each generation of offspring, leading to variation and evolution. It covers topics from school biology, such as how plants work and how animals, including humans, work, and goes on to ecology and biotechnology.

Beyond school science, however, it covers the background to the latest medical technology and biotechnology: how gene therapy works, what stem-cell research is achieving, and how our immune systems, boosted by vaccines, are in an arms race with ever-mutating viruses and other pathogens.

At DK, we believe in the power of discovery.

So why stop there?

How Biology Works is part of DK's widely successful How Stuff Works series.

My dogs love their "keys".
Size: X-Small
My dog loves this. The only negative is that he does chew through it and I have to pick up the pieces or hope that he's not eating it.

Not long lasting for a chewer!
Size: Medium
These are massive! I have a golden retriever puppy and she chewed through the yellow ring very quickly. They keys are much more durable.

Great for puppies- have purchased several times
Size: X-Small
I have purchased this toy for a couple of the puppies in my life and they always love it. It’s not noisy, it’s made for puppies to chew (so it’s not too hard), and it’s fun for them to carry around with the different keys and key ring. A little pricey, but it always lasts a very long time- longer than they are a puppy!

Safe and Entertaining Chew Toy
Size: Medium
My dog absolutely loves this toy! She gets hours of chewing time out of it, and I feel so much better knowing the keys are made of a material that’s gentle on her teeth. Unlike harder toys that can chip teeth, this one is durable yet safe, and it keeps her happily entertained. Definitely a great choice for any dog that loves to chew.
