Why Darwin Was Wrong ABSTRACT: Jerry Fodor argues that Darwin was wrong about "natural. (1) Darwin's theory of evolution is not a "covering-law" scientific theory of the sort we. Quick Answer. Lamarck’s theory on evolution was wrong because organisms pass down traits through predetermined genetic information, not based on environmental adaptations during their lifetime. Lamarck proposed that if an organism used a certain muscle differently, like a giraffe having to consistently reach up higher on a tree for leaves,
