And we can evolve bacteria and we can evolve plants and we can evolve animals, and we're now reaching a point where we really have to ask, is it really ethical and do we want to evolve human beings?
Podem evolucionar bactèries i també plantes i podem evolucionar animals, i estem arribant a un punt en el qual ens hem de preguntar, és ètic i ens interessa evolucionar éssers humans?
