Genetic variation and mutations are really important for how species adapt to their surroundings! Let’s break down how they work:
Genetic Variation: This means the differences in DNA among people or animals in a group. Think of it like having a big toolbox—more different tools mean a better chance of fixing problems when things change in the environment.
Mutations: These are random changes that happen in the DNA. Not all mutations are good; some can be harmful or not make any difference. But some can actually help an organism survive better! If a mutation gives an animal an advantage, that trait can be passed down to its babies when they reproduce.
Natural Selection: Sometimes, the environment can become challenging, like when the climate changes or when predators show up. Animals or plants that have helpful traits are more likely to survive and have babies. Over time, this leads to the species changing to fit their environment better.
In short, genetic variation and mutations are the building blocks that help evolution happen!
