Charles Darwin came up with some new ideas about how living things change over time. Here are the main points:
Natural Selection: Darwin believed that animals and plants that are better suited to their surroundings are more likely to survive and have babies. This idea is sometimes summed up as "survival of the fittest."
Descent with Modification: He thought that different species come from common ancestors over a long time. This helps us understand why some living things look alike while others are different.
Gradualism: Darwin said that changes in species happen slowly over many years. This is different from some other scientists who believed changes happen suddenly.
Sexual Selection: He also talked about how certain traits can develop because one sex prefers certain features in the other sex, like bright colors or impressive displays.
In the end, Darwin’s ideas are key to how we understand evolution today.
