Charles Darwin's ideas changed how we think about natural selection. Natural selection is how certain traits become more common in a group of living things over time. Let's break it down!
1. What is Natural Selection?
Darwin suggested that individuals with traits that fit their environment the best are more likely to survive and have babies. For example, in a group of giraffes, those with longer necks can reach higher leaves. This helps them eat better and have more babies compared to giraffes with shorter necks.
2. Differences and Competition:
Darwin pointed out that there are differences among individuals in a species. Some might be faster or better at hiding. These differences mean not everyone will survive. Think about a group of rabbits where some are white and some are brown. In a snowy place, the white rabbits are less likely to be seen by predators.
3. Traits Passed Down:
Traits that help animals survive often get passed down to their babies. If those long-necked giraffes have young ones, many of their babies will likely also have long necks. This makes long necks more common in the group over time.
In conclusion, Darwin's ideas teach us how species change and grow through natural selection, showing us the wonderful variety of life!
