The main difference between Lamarckian and Darwinian evolution is that the former posits that inherited traits are developed through use and that organisms evolve in a linear progressive fashion. Darwinism, on the other hand, maintains that species die or survive based on natural selection and that species do not evolve linearly but the lines of species branch out in time.

Lamarck held that individuals pass on the traits they acquire during life. Darwin that individuals pass on the traits they are born with and that help them reproduce. The classic experiment was mice and their tails. Lamarck would say that by cutting the tails off of mice, later generations would be born tailless. Darwin would have held that if shorter tails provided a better survival chance, then tailless mice would, through natural selection, develop. The end result was to prove Lamarck wrong.
