On one hand, co-evolution and specialization of natural enemies should enhance their effectiveness in exploiting hosts/prey and reducing pest populations through density-dependent processes (Hassell 1978; May and Hassell 1988).
On the one hand, the evolution of large stretches of sequences capable of positioning nucleosomes may have co-evolved with the emergence of CTSs within the corresponding linker regions.
Thus the evolution of steroid system intermingles two distinct processes, the evolution of the receptor on one hand, and the evolution of the ligand on the other.
If understanding the nature of science causally impacts the acceptance of evolution, then we should find a correlation between our measures for understanding the nature of science, on the one hand, and accepting evolution, on the other.
Gene duplications on the one hand, and the evolution of regulatory sequences on the other, are thought to be among the most important mechanisms for the evolution of new gene functions.
Another part has to do with "correlations between the eclipse of the messianic" -- a favorite phrase, that -- and the 'recession into empty phrasing' of 'God' on the one hand and the evolution of nonrepresentational and aleatory art forms on the other".
Even more lamentable is the way that Horgan creates a dichotomy between "genes", "biology", "innate" and "evolution" on one hand, and "culture" on the other hand, as if human culture lies completely outside the orbit of evolutionary theory.
On one hand, the theory of evolution is a province of science.
On one hand, they speak loftily about artistic evolution and music being "an invitation to a sonic journey"; on the other, they wear kitschy helmets straight off the covers of Eighties-era Isaac Asimov paperbacks.
