Darwin studied various modern organisms, particularly their physical traits, behaviors, and geographical distributions, which revealed patterns of similarity and variation. He observed that similar species often inhabited similar environments, suggesting a common ancestry. This led him to propose the idea of descent with modification, where species evolve over time through natural selection, adapting to their surroundings while retaining ancestral traits. His observations of finches in the Galápagos Islands were particularly influential in shaping his theory of evolution.
No. There is no real evidence about that
he proposed the theory of natural selection in 1838. he also suggested that humans evolved from monkeys.
Many famous figures have praised Charles Darwin for his groundbreaking contributions to science. Albert Einstein admired Darwin's work for its profound impact on our understanding of life and evolution, while Stephen Jay Gould regarded him as a pivotal figure in the history of biology. Additionally, Richard Dawkins has lauded Darwin as a "great thinker" who fundamentally changed how we view ourselves in relation to the natural world. Overall, Darwin is celebrated for his revolutionary ideas that laid the foundation for modern evolutionary biology.
Darwin's theory made it clear that ancestral relationships existed between species, and the use of these relationships became the overarching consideration of classification schemes. It wasn't until the "modern synthesis" of molecular biology that we were able to resolve some conflicts inherent in classification schemes based solely on interpreted physiological relationships. Linnaeus had made great strides in the design of the hierarchical taxonomy, and that taxonomy compellingly demonstrated the existence of evolutionary change.
Darwin's idea of evolution by natural selection, supported by fossil evidence, illustrates how species change over time through gradual adaptations to their environments. Fossils provide a historical record, showing transitional forms that reveal the common ancestry of diverse species. Modern genetics has further reinforced Darwin's theory by demonstrating how hereditary traits are passed down and can be influenced by environmental pressures, leading to evolutionary changes. Together, these concepts form a comprehensive understanding of the evolution of life on Earth.
Organisms on island clusters were very similar to each other and to nearby mainland species.
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 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 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.
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.
