A recent paper in J. theor. Biol. has challenged the proposed application of punctuated equilibrium models to the evolution of reptilian viviparity and placentation. While clarifying some aspects of the models, the paper's criticisms reflect misinterpretations of the literature and an unnecessary re

We consider an individual-based model of evolution. Species emergence as segregation of the population on to discrete positions in a hyper-cubical genotype space. The model emphasises interaction between coexisting genotypes. Although the rate of the micro-dynamics, consisting of reproduction and ki

Three principal modes of embryonic nutrition occur in the vertebrates, viz., 1) uitellogenesis, the sequestering of yolk, synthesized in the liver, in the oocyte; 2) histotroph, nutrient substances supplies to the embryo in viviparous animals by secretory activity of the uterus; or 3) placenta, the
