ABSTRACT:

Microorganisms growth, embryogenic development and other biological processes are temperature dependent (Cossins and Bowler, 1987). Here we show that an equation deduced from the Theory of Rate Processes (Glasstone et al., 1941; Fain, 1980), reproduces the experimental data particularly well, so improving the Arrhenius expression. Since the evolution of the species could be considered mainly as a rate process of the DNA molecule, it seems reasonable to accept, as a hypothesis, that the said equation could be applicable to the study of evolution of species.

We have found that the main phenomenological characteristics concerning to such evolution can be explained from the mentioned equation, which for this reason could be considered as a reflect of the evolutionary phenomena.

Keywords: biological, evolution, rate, speciation, temperature, punctuated equilibrium.
