Wade thinks that a focus exclusively on the Wade’s tactic is particularly dangerous in the variation on coding regions of the human genome public arena, as many readers do not have access will get us answers. But he does not recognize that to the wide range of current genomic and evolu- humans have only about 19,000 genes (many fewer tionary data and theory and do not understand than many less complex forms of life) and that the complexities and rigor of the peer-reviewed even within these regions there is much variation publication process by which data are assessed and in structure.

We know that “genes” don’t do which Wade writes.
