Abstract
The results of detailed analysis of interspecific correlations between allozyme heterozygosity, standard metabolic rate, rate of sexual maturation, longevity and linear body size are presented (Fig. 1). The purpose of this work was to determine key casual relationships by means of partial correlation analysis. It was found that the relationship between heterozygosity and metabolic rate lies in the basis of correlations shown in Fig. 1, whereas the genetic determination of the other three characters was mediated by this relation. The highly significant negative correlation between the standard metabolic rate and the age of the first reproduction was demonstrated for the first time. The problem set here follows logically from the results of investigations carried out in the late 20th century [1‐3]. Comparative biometrical analysis of 77 species of animals and 30 species of arboreal plants have shown that the individual genome heterozygosity, age of the first reproduction, longevity, and linear body size are related to one another by highly significant correlations [1, 2]. The analysis of partial correlations have uncovered key causal relationships: a high individual heterozygosity determines high rates of development and sexual maturation and early age of the first reproduction while decelerating the post-reproduction growth and reduces the lifespan [1, 2].
