Lamark
The theory of natural selection, which was also embraced by another biologist, Lamark.
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
Jean-Baptiste Lamarck suggested an idea that Darwin would later expand upon. Lamarck suggested that any changes a creature underwent during its lifetime would be passed down to the offspring. He also believed unused parts would just go away over time, due to this.
Lamarck's theory is that he thought that the long necks from giraffes come from other species of mammals.
Lamarck led the way for and had ideas that helped Darwin. However, his observations regarding the mechanisms of evolution were, with the exception of one, totally backwards. To summarize Lamarck, he hypothesized that organisms somehow had a choice in their traits and could change to fit the environment (he called these ideas his theories of need and his theory of use and disuse). The part he was correct on was that should an organism change, they would pass the traits on to their offspring. Darwin said, basically, the opposite. Darwin observed that organisms were born with slight differences (variations) and those variations might give some members of a species an advantage in the struggle to survive in the environment. The reward for survival was that the organism got to reproduce and pass those traits on to their offspring. Of course, the offspring might show some variation and the whole process would continue to repeat. However, the bottom line with Darwin (and contrary to Lamarck) was that an organism had no choice in its traits as an organism is born with or without the advantage. Darwin, without knowing its mechanisms, recognized that genetics played a part in evolution. Darwin died not knowing of Mendel's work on genetics which, of course, substantiates Darwin's theory.
He didn't. Lamark's theory of acquired characteristics preceded Darwin's theory by some years. Almost 50 years.

Jean Babtist Lamark
He is considered by many to be the father of the Theory of Evolution, though his uncle and Lamark had the genesis of that idea.
Lamark's theory perhaps. Acquired characteristics clash with heredity.
Darwin introduced the modern theory of evolution by natural selection, but it was also introduced by Lamark and other earlier biologists but Darwin was first to theorize about natural selection as the mechanism.
Theories are just that. Theories are unproven ideas by people to explain a certain phenomena.

Darwin believed that organisms evolved due to natural selection. Whereas Lanmark suggested that the characteristics acquired during an organisms life i.e. academic ability, could be passed to the next generation.
Because it was Darwin who made it a scientifically plausible explanation, by providing a mechanism by which evolution could occur....Natural Selection.
LaMark Carter was born in 1970.
Other scientists like Lamark Baptist Wallace helped by going out and exploring with him and publishing his articles.
