Lamarck Posited the concept of acquired characteristics being heritable and the organisms " need " to adapt physiological parts, such as giraffes " needing " longer necks. Needless to say both of these main concepts of Lamarck's were wrong.
Darwin posited the theory of evolution by natural selection that saw selected variations of organisms evolving over time by their progeny inheriting favorable characteristics. Darwin had the evidence that Lamarck did not and his theory, with modifications, is still the best explanation of evolution and the origin of species extant.
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.
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
Lamarck thought that evolution could be effected by changes in the body, rather that strictly by the survival (or rather the death) of offsprings.
Do Lamarck's theories provide a good explanation for the change in months? Why or why not?
lamarckism
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.
Lamarck
They both propose that organisms are not immutable, but changes over time. However the mechanisms of the two theories are very different.

The Beagle
Darwin's theory made more sense and was proven true.
