Darwin observed variations in traits among individuals of the same species, which he attributed to differences in their habitats and environments. He also noted that these variations could be passed down from generation to generation, leading to changes in populations over time. This observation, along with evidence from comparative anatomy and biogeography, led Darwin to propose the idea of descent with modification, or the process of evolution by natural selection.
Darwin studied a diverse range of modern organisms to support his idea of descent with modification, also known as evolution through natural selection. By observing variations within and between species, as well as the process of adaptation to different environments, he was able to build a compelling case for the gradual transformation of species over time. Studying modern organisms provided evidence for the idea that all life on Earth is interconnected through a common ancestor.
Darwin was intrigued by the variations he observed within and among species, along with the geographical distribution of species. The diverse adaptations and similarities in characteristics among related species, combined with the geological evidence of Earth's changing landscapes over time, led him to propose the idea of descent with modification, which later became known as evolution by natural selection.
Organisms on island clusters were very similar to each other and to nearby mainland species.

The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
