Downgrade Quotes (2 quotes)
A complete theory of evolution must acknowledge a balance between external forces of environment imposing selection for local adaptation and internal forces representing constraints of inheritance and development. Vavilov placed too much emphasis on internal constraints and downgraded the power of selection. But Western Darwinians have erred equally in practically ignoring (while acknowledging in theory) the limits placed on selection by structure and developmentwhat Vavilov and the older biologists would have called laws of form.
