Abstract
“On the Origin of Species” by Charles Darwin changed the biology theories and the biblical creationism was replaced by a new vision of the world. From this new perspective, also the theories by Lamarck were considered incorrect, because the adaptations achieved by animals during their life could not be transmitted hereditarily. Moreover, after fifty years, the data collected by Gregor Mendel induced biologists to introduce the concept of gene and hereditary characteristics, underestimating the role of the environment
