Here's a breakdown:
* Charles Darwin (along with Alfred Russel Wallace) is credited with formulating the theory of natural selection, which is the primary mechanism driving evolution. His book "On the Origin of Species" (1859) provided a comprehensive explanation of natural selection and its role in the diversification of life.
* Early Ideas: The idea of evolution existed before Darwin, with thinkers like Jean-Baptiste Lamarck proposing the theory of inheritance of acquired characteristics.
* Other Contributors: Many other scientists contributed to the understanding of evolution, including Alfred Russel Wallace, Gregor Mendel, Thomas Huxley, and others.
So, while Darwin's work revolutionized the understanding of evolution, it's inaccurate to say that he formulated the concept entirely on his own. He built upon the work of earlier scientists and his own observations, ultimately solidifying the theory of evolution by natural selection.
