Evolution Theory Natural Selection Proposers
The theory of evolution by natural selection is a cornerstone of modern biology. Identifying its originators is crucial for understanding evolutionary science.
Darwin's Contribution
Charles Darwin is widely credited with proposing the theory of evolution by natural selection. His extensive research and observations, particularly during his voyage on the HMS Beagle, formed the basis of his seminal work, 'On the Origin of Species'.
Wallace's Independent Work
Alfred Russel Wallace independently conceived the theory of evolution by natural selection around the same time as Darwin. His manuscript outlining the mechanism prompted Darwin to publish his own detailed findings.
Other Scientists
While influential biologists, the other options proposed different ideas:
- Jean Baptiste Lamarck proposed a theory of inheritance of acquired characteristics, which differs from natural selection.
- Georges Cuvier was a key figure in paleontology and advocated for catastrophism, not gradual evolution by natural selection.
Therefore, both Charles Darwin and Alfred Russel Wallace independently proposed the theory of evolution by natural selection.
The correct options are A (Charles Darwin) and C (Alfred Russel Wallace).
