That they were both transformationists, a word the meant in those days one thought organisms evolved over time, and thought species arose by natural processes. The mechanisms proposed by them varied a great deal though.
Lamarck thought acquired traits were past on, but he was prover wrong by Darwin and his natural selection idea.
Jean-Baptiste Lamarck
Lamarck believed that there was a form of evolution, but contrary to Darwin after him, he believed that the characteristics an organism acquires during his life are inherited by its descendants. For more on Lamarck's hypothesis, see the related question below.
Darwin's theory was that organisms were born with slight variations, and nature selected some of those, introducing changes within species.Lamarck proposed that organisms changed throughout their lives, and that those acquired changes where heritable.It turns out Darwin was right and Lamarck not so much.
In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.
i would agree with you. i belive they both had the same theory.
Darwin did not actually meet Lamarck in person. Lamarck's ideas on evolution were published before Darwin's time, and Darwin was familiar with them through his readings. Darwin's theory of natural selection differed from Lamarck's theory of inheritance of acquired characteristics.
Darwin read the book Lamarck wrote and said that he did not get one idea from it as it was ludicrous in content. So, Lamarck would be the one scientist that did not influence Darwin according to Darwin.

Darwin, of course. Lamarck did not have the evidence to back up his acquired characteristics and use and disuse concepts, but Darwin had massive amounts of evidence and well structured arguments for his theory of natural selection.

?Mendel, widely acknowledged as the first geneticist.the answer is either lamarck or darwinit's lamarck. he believed that characteristics developed by parents are passed on to their offspring.
