🇬🇧🇪🇸 mutation - mutación : English Lesson

Meaning of "mutation" ("mutación"), detailed definition, and a short video lesson below.

A mutation is a change in the tiny instructions inside your body called genes. These genes tell your body how to grow, what color your eyes are, how tall you might be, and many other things. Sometimes, when your body makes new cells, one of these gene instructions changes by accident. That change is called a mutation. Most mutations are small and you don’t even notice them, but some can cause new traits, like a different color of fur on an animal or a plant that grows taller than others. Over a long time, many mutations can help living things adapt and survive in their environment.
