Today, Lamarck is unfairly remembered in large part for his mistaken explanation of how adaptations evolve. He proposed that by using or not using certain body parts, an organism develops certain characteristics. (A) There is no evidence that this happens. Still, it is important to note that Lamarck proposed that evolution occurs when organisms adapt to their environments. This idea helped set the stage for Darwin. (B) Lamarck thought that these characteristics would be passed on to the offspring. Lamarck called this idea inheritance of acquired characteristics. (C) For example, Lamarck might explain that a kangaroo’s powerful hind legs were the result of ancestors strengthening their legs by jumping and then passing that acquired leg strength on to the offspring. However, an acquired characteristic would have to somehow modify the DNA of specific genes in order to be inherited.
