Mutations play a big role in how living things change over time!

Simply put, mutations are changes that happen in the DNA, which is like a set of instructions for our bodies. These changes can happen for different reasons, like mistakes made when the DNA copies itself or when living things are affected by their surroundings. Here’s more about how mutations help create genetic variety:

1. Types of Mutations:

   • Point Mutations: This is when just one part of the DNA changes, like swapping an A for a G.
   • Insertions or Deletions: This means adding or taking away pieces of DNA. These changes can really change how proteins work.

2. Impact on Traits:

   • Some mutations don’t seem to affect anything, while others might help or hurt. For example, a mutation could change the color of flowers, making them more attractive to bees and butterflies!

3. Evolutionary Significance:

   • Mutations help create new versions of genes, known as alleles, which adds variety to a group of organisms. This variety is super important for natural selection. It lets some living things adapt better to their environment than others.

In short, mutations are like little game-changers in nature. They keep mixing things up in the gene pool and help evolution happen!
