what is the key part of darwins idea in natural selection?
Weegy: Darwin's theory of evolution has four main parts: 1. Organisms have changed over time, and the ones living today are different from those that lived in the past. 2. All organisms are derived from common ancestors by a process of branching. 3. [ Change is gradual and slow, taking place over a long time. This was supported by the fossil record, and was consistent with the fact that no naturalist had observed the sudden appearance of a new species. [This is now contested by a view of episodes of rapid change and long periods of stasis, known as punctuated equilibrium]. 4. The mechanism of evolutionary change was natural selection. This was the most important and revolutionary part of Darwin's theory, and it deserves to be considered in greater detail. ] (More)
