I became some-what dissatisfied with the substitution of a two-dimensional surface of selective values for the true pattern, which is multidimensional both among and within loci. I decided that this pattern should be explicitly assumed to underlie the two-dimensional one of the diagram and that its origin should be at whatever peak was under consideration. The contours should be considered as merely symbolic of the complex pattern to a greater extent that before. However, I did not arrive at any changes that should be made in the diagrams as presented.This seems to me not to recant anything about the utility of fitness landscapes (aka surface of selective values), apart from admitting that two-dimensional landscapes are symbolic of the multi-dimensional nature of them.
