Charles Darwin proposed that species change over time through the process of natural selection. He suggested that individuals within a species exhibit variations, and those with traits better suited to their environment are more likely to survive and reproduce. Over generations, these advantageous traits become more common in the population, leading to gradual evolutionary change. This mechanism explains the adaptation of species to their environments and the emergence of new species over time.
Charles Darwin
Charles Darwin attempted to answer the question of how species evolve and adapt over time. Specifically, he sought to understand the mechanisms behind the diversity of life on Earth and the processes that drive natural selection. His observations during the voyage of the HMS Beagle led him to propose that species change through gradual processes influenced by environmental pressures. This foundational inquiry laid the groundwork for modern evolutionary biology.
Darwin's observations during his voyage on the HMS Beagle, particularly in the Galápagos Islands, significantly shaped his theory of evolution. He noted the variations in finch beaks adapted to different food sources, which suggested that species could change over time based on their environment. Additionally, he observed the similarities and differences among species on various islands, supporting the idea of common descent. These observations led him to propose natural selection as the mechanism driving evolutionary change.
Darwin collected enormous numbers of fossils and specimens of extant species, and made thousands of observations of changes. His observations clearly documented that species undergo change over time. Since Darwin's time we have gathered much more data about the processes of evolutionary change, such that the theory of evolution is now considered the foundational concept of modern biology.
Jean-Baptiste Lamarck suggested an idea that Darwin would later expand upon. Lamarck suggested that any changes a creature underwent during its lifetime would be passed down to the offspring. He also believed unused parts would just go away over time, due to this.
Darwin proposed that over a long time, natural selection could lead to the gradual change and divergence of species from a common ancestor, resulting in the formation of new species through the process of adaptation to their environment.

Darwin proposed that the differences between species were caused by natural selection, where individuals with advantageous traits are more likely to survive and reproduce, leading to the gradual accumulation of adaptations over time.
Darwin discovered unique species of finches and tortoises in the Galapagos Islands that helped shape his theory of evolution by natural selection. He observed how these species had adapted to different environments on different islands, leading him to propose that species can evolve over time to better suit their surroundings.
Darwinism: it was discovered by Charles Darwin and so named.
Darwin originated the idea that living things evolve by the means of natural selection. He discovered that species change over time and that they adapt to their habitats. He wrote the Origin of the Species, which caused a lot of controversy.
Charles Darwin proposed the theory of evolution through natural selection. This theory suggests that species evolve over time through the process of genetic variation, natural selection, and adaptation to their environment. Darwin's work revolutionized the understanding of the diversity of life on Earth.
Charles Darwin was one of the first people to propose that evolution occurs through descent with modification and the natural selection of inherited traits.Of course he had lots of things to say on the subject. To get some idea of everything he had to say you should probably pick up his On the Origin of Species.
Darwin observed that high birthrates and a shortage of life's necessities forced organisms into a constant "struggle for existence", both against the environment and against each other is which led Darwin to propose his theory of constitution
Charles Darwin called his mechanism of change "natural selection." This process favors the survival and reproduction of organisms that are best adapted to their environment, leading to the gradual change of species over time.
When plants and animals they faced different and harder conditions then what they faced in their normal habitat. Perhaps, Darwin hypothesized, the species gradually changed over many generations and became better adapted to the new conditions gradual change in a species over time is called evolution.
