Expressions (18) show explicitly how the efficiency-skill endowment functions tj(s)/a(s) determine the empirical form of the production function. Conversely, a given production function implies endowment functions that are consistent with it. For example, what forms of tA(s)/a(s) and tB(s)/a(s) imply that F(NA,NB) has a constant elasticity of substitution? The answer is easily obtained. Normalize a(s) = \, substitute the expression for a in (19) into a(p) = a and differentiate with respect to p to obtain the restrictions t'j/t'j= a(t'j/tj) for all p, j = A,B.

The connection is not really very remote. One of the most striking phenomena of the living world is its organization into species, of which there are hundreds of thousands, or even millions, each of them with a greatly varying number of members. Though vastly more complicated, this pattern has some analogy to that of the firms along a road, or of the discretely varying shoe sizes. Each species may be compared to one size of shoe, and its members to the shoes produced of that size. The advantages and disadvantages of the biological pattern can therefore not be too dissimilar from those of the economic pattern.
