" "Barbieri chides that “natural selection is the long-term result of molecular copying and would be the sole mechanism of evolution if copying were the sole basic mechanism of life.”15 But it isn’t. While genes can be their own template and copy themselves, proteins cannot. Proteins cannot be made by copying other proteins. The tricky thing is that only molecules that can copy can be inherited, so the information about how to make the proteins had to come from the genes. Barbieri notes that the outstanding feature of the very early protein makers “was the ability to ensure a specific correspondence between genes and proteins, because without it there would be no biological specificity, and without specificity there would be no heredity and no reproduction. Life, as we know it, simply would not exist without a specific correspondence between genes and proteins.”16

The tension felt in the modern world between those who look at the confluence of neuroscientific data, historical data, and other information illuminating our past and those who simply accept received wisdom as their guide in life is real and profound. Yet it may not be as divisive as one would think. It appears that all of us share the same moral networks and systems, and we all respond in similar ways to similar issues. The only thing different, then, is not our behavior but our theories about why we respond the way we do. It seems to me that understanding that our theories are the source of all our conflicts would go a long way in helping people with different belief systems to get along.
Marc Kirschner and his Berkeley colleague John Gerhart.20 They wondered whether modern creatures have cellular and developmental mechanisms with the characteristic of what is called evolvability. That is, do they have the ability to generate heritable phenotypic variation? And is the characteristic of evolvability itself under selection pressure? That is, will biological systems that produce more phenotypic variations that can be passed on to their offspring be more
When people talk about training, they generally mean taking an amorphous mind and shaping it into something. It is the sort of thing that goes on at universities that are not yet in possession of high-quality students. It is not the sort of thing that should go on at serious centers of discovery. Mentoring, on the other hand, is productive, necessary, and enjoyable.
