Complication of Animal Genomes during Evolution Slowed Down after Cambrian Explosion
We have published a new article about the Evolution of Life on Earth.
Skladnev D. A., Klykov S. P., Kurakov V. V. Complication of Animal Genomes in the Course of the Evolution Slowed Down after the Cambrian Explosion. Evolution: Development within Big History, Evolutionary and World-System Paradigms. Yearbook / Ed. by L. E. Grinin and A. V. Korotayev. Volgograd: Uchitel, 2013. Pp. 249–256.

For the first time, the growth rate of minimal animal genome size is shown to
slow down in the course of evolution from prokaryotic forms to mammals after
the Cambrian explosion. There is proposed an original mathematical model
which takes into account a multiphase character of development and importance
of multidirectional trends in the evolution. The authors explain from the
biological point the exponential change of minimal genome size in the beginning
of the evolutionary process, slowing down after the period of the Cambrian
explosion as well as reveal certain parameters of the evolutionary processes
as a result of the model application. According to the proposed model, the
S-shaped curve with distinct inflexion point adequately describes the increase
of minimal genome size.
Keywords: evolution equations, mathematical modeling, genome size, Cambrian
