Evolution

Today, we will learn about evolution, which is how living things change over time to adapt to their environment.


Section 1: What is Evolution?

Evolution is the process where living things gradually change and develop over many generations. For example, birds might develop longer beaks to reach food in tall trees.


Section 2: Types of Evolution

There are two main types of evolution:

  1. Microevolution: Small changes that happen within a species, like different colors of butterflies in a forest.
  2. Macroevolution: Big changes that lead to the creation of new species, like how wolves evolved into different types of dogs.

Quick Activity:

Look around your home or school and see if you can find examples of how living things have adapted to their environment. Draw or write about what you observe!


Summary:

Evolution is all about how living things change and adapt over time to survive in their surroundings.
