Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.
- Very good! You've correctly deduced an important evolutionary process known as co-evolution. This phenomenon is a key to understanding not just pre...

- Of course, natural selection just selects for the organisms that will be the most fit (have the most offspring) in a particular environment. One si...
- Natural selection is a mechanism that makes any species - be it a plant, animal, fungus, bacteria, you name it - better adapted to their environmen...

- Darwin's concept of natural selection was based on several key observations: -Traits are often heritable. In living organisms, many characteristics...
- There have been other theories but they disagree with observations that the theory of evolution through natural selection explains.
Darwin's theory of evolution by natural selection underlies all modern biology. It enables us to decipher our genes and fight viruses, as well as to understand Earth's fossil record and rich biodiversity.
May 23, 2024 · human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture -bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Oct 19, 2023 · Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
