In 1831, Charles Darwin embarked on a transformative voyage to the Galapagos Islands, where he observed finches with varying beak shapes. These observations led to his theory of evolution by natural selection, suggesting that organisms better suited to their environment are more likely to survive and reproduce. Over time, Darwin's hypothesis evolved into a scientific theory supported by fossil, embryological, anatomical, and genetic evidence. Fossils reveal evolutionary changes over time, while embryological studies show similarities among species. Anatomical evidence includes vestigial, homologous, and analogous structures, and genetic evidence highlights DNA as a link between species. This comprehensive evidence supports the theory of evolution and helps scientists trace evolutionary history.
