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.
Darwin studied modern organisms to understand how they descended from common ancestors and underwent modification over time through the process of evolution. He observed variations in traits among species and how these traits adapted to different environments, which contributed to their survival and reproduction. This concept of descent with modification emphasizes that species are not static but continually evolve, reflecting changes in both genetic variation and environmental pressures. Through his observations, Darwin laid the foundation for the theory of natural selection, illustrating how species adapt and diversify over generations.
Charles Darwin is linked with the natural system of classification because his theory of evolution by natural selection provided a scientific basis for organizing living organisms based on their evolutionary relationships. Darwin's ideas emphasized that similarities among species reflect common ancestry, leading to a hierarchical classification system that groups organisms according to shared characteristics and evolutionary lineage. This approach paved the way for modern taxonomy, which classifies organisms not just by physical traits but also by genetic and evolutionary connections.
Darwin's theory of evolution is based on natural selection, where organisms with advantageous traits are more likely to survive and reproduce, passing those traits to future generations. In contrast, Lamarck's theory, known as Lamarckism, posits that organisms can acquire traits during their lifetime based on their needs or environmental pressures and then pass those acquired traits to their offspring. While Darwin emphasizes genetic variation and survival of the fittest, Lamarck focuses on the direct adaptation of individuals to their environments over generations. Ultimately, Darwin's ideas are supported by modern genetics, while Lamarck's have been largely discredited.
Darwin's ideas fundamentally transformed the classification system by introducing the concept of evolutionary relationships among species. His theory of natural selection emphasized common descent, leading to classifications based on phylogenetic relationships rather than merely morphological similarities. This shift encouraged the use of evolutionary trees, or cladograms, to represent the connections between species, ultimately laying the groundwork for modern taxonomy and the understanding of biodiversity.
No. There is no real evidence about that
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.

Organisms on island clusters were very similar to each other and to nearby mainland species.
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.
