On the natural selection of body mass allometries

The inter-specific body mass allometries were mathematically deduced by population dynamic feedback selection in 1995 (Witting, 1995, 2017). This selection is entangled, and the present publication uses the covariance among the life histories of birds and mammals to visualize some of the underlying natural selection causes. This includes a graphical deduction of the allometric exponents (Fig. 1).

For details see Witting (2023).
