Molecular biology is at a turning point and we have to accept that both nature and nurture—in the traditions of Darwin and Jean-Baptiste Lamarck, respectively—coexist in the laws governing life. The weight of the new evidence from prion research is simply too powerful to ignore. Biologists need to get used to the idea that there’s no end in sight when it comes to new insights and scientific breakthroughs—an idea that has long been accepted by physicists who are subject to regular scientific revolutions. I wonder if knowledge is, like the universe, basically endless and in constant expansion, just as the complexity of life itself is also expanding infinitely.
