Sure! Environmental changes can really affect how different groups of living things, like plants and animals, change over time. Here’s how it works:
Mutations: These are random changes in the DNA that can lead to new traits. For example, a plant might change in a way that helps it survive with less water.
Natural Selection: When something in the environment changes, like if it gets hotter outside, certain traits that help living things survive become more common. For instance, lizards in warmer places might get lighter colors to help them hide from predators better.
Gene Flow: This happens when groups of living things move to new places and mix their genes with others. For example, when birds travel to new areas, they can share their genes with local birds, which can lead to more variety.
These different processes work together to create the amazing diversity we see in nature!
