What this book is about
- Grow: Secrets of Our DNA starts by explaining how living things – from plants to animals to humans – grow and change over time.
- The book highlights diversity, showing how different people can look, and why seeing yourself represented in books matters for children.
- It explains how organisms grow at different rates. Some, like fish or plants, grow quickly when conditions are right. Others, like trees or clams, grow slowly and live longer.
- Growing isn’t just about getting bigger. Caterpillars turn into butterflies, seeds become trees, and children grow into adults – with bodies changing shape and becoming more complex along the way.
- The book introduces DNA as the secret code that contains all the instructions for growth and development. It explains how half comes from your biological mum and half from your biological dad, and why that makes each person unique.
- It shows how DNA links us not just to our parents but also to animals, plants, and even our ancient ancestors – with chimpanzees being our closest relatives.
- Complex ideas like cell division, inheritance, and evolution are explained simply, with engaging illustrations to bring the science to life.
- It’s a fascinating introduction to genetics that can spark meaningful conversations with kids about bodies, families, diversity, and how we are connected to the natural world.
