Darwin used the ideas of natural selection and descent with modification to explain evolution. Natural selection is the process by which individuals with favorable traits are more likely to survive and reproduce, passing those traits on to their offspring. Descent with modification refers to how species change over time through the accumulation of small changes in their inherited traits.
First, he had no idea how heritable traits pass from one generation to the next. Second, although variation in heritable traits was central to Darwin's theory, he had no idea how that variation appeared.
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.
Charles Darwin is often referred to as the father of evolution. He proposed the theory of natural selection to explain how species evolve over time through a process of adaptation to their environment. His work revolutionized the field of biology and remains a foundational concept in the study of evolution.
Alfred Russel Wallace, a contemporary of Charles Darwin, independently proposed a theory of evolution by natural selection that was similar to Darwin's. Wallace's work on natural selection prompted Darwin to publish his own views on the subject. The two scientists jointly presented their work in a paper in 1858.
Charles Darwin coined the terms "natural selection" and "survival of the fittest" to describe the process of evolution by which species adapt to their environment over time.
natural selection and common descent
Darwin worked on his theory for 20 years. After learning that another naturalist, Alfred Russel Wallace, had developed similar ideas, the two made a joint announcement of their discovery in 1858. In 1859 Darwin published 'On the Origin of Species by Means of Natural Selection'.
He did not influence Darwin and Darwin did not know who he was. Darwin's ' blending theory of inheritance ' was wrong and though Darwin did not particularly like the theory he could think of nothing better to explain inheritance. There is a legend that Darwin had a copy of Mendel's work in his desk but could not read it because it was in German. Just a legend, though.
First, he had no idea how heritable traits pass from one generation to the next. Second, although variation in heritable traits was central to Darwin's theory, he had no idea how that variation appeared.
Yes, Charles Darwin had five siblings - three brothers and two sisters. He was the fifth of six children born to Robert Darwin and Susannah Darwin.
Charles Darwin was put on the 2009 two pound coin.
The two islands off the Australian coast at Darwin are Bathurst Island to the west and Melville Island to the east.

James Hutton and Charles Lyell were the two scientists that helped Darwin recognize how old the Earth is.
