The effects of virus-driven energy theft on brain development in mammals typically occur more rapidly during gestation and early prenatal development. That’s why the connection from biophysically constrained RNA-mediated amino acid substitutions and protein folding chemistry during life history transitions has been largely ignored.
…coordinated structural plasticity is consistent with stable, yet flexible, decorrelated sensory representations. Together, our study reveals that persistent, coordinated synaptic structural plasticity between interneurons and principal neurons is a major mode of functional plasticity in the OB.
Decorrelation links ecological variation to ecological adaptation via biologically-based cause and effect.

“We expected to see the synapses gradually stabilizing, as happens during brain development. But astonishingly, these synapses proved to be highly dynamic throughout the life of the new neurons. Also, these dynamics were reflected in the principal neurons, their primary synaptic partner,” explained first author, Kurt Sailor, from the Institut Pasteur.
The experience dependent de novo creation of olfactory receptor genes links ecological variation from RNA-mediated amino acid substitutions to the physiology of reproduction and cell type stability in all cell types of all vertebrates and invertebrates via biophysically constrained protein folding chemistry. That fact eliminates the claims of all neo-Darwinian theorists and big bang cosmologists from any further consideration whatsoever in the context of biologically-based cause and effect.
