<span>Sympathetic nervous system accelerates the heart rate, decrease movement of the large intestine, and perspiration.

Two groups of scientists, including researchers at the Max Planck Institute of Molecular Genetics in Dresden and the Max Planck Institute for Evolutionary Biology in Plön, have now succeeded in demonstrating, for the first time, that parallels exist between individual development and phylogeny on the level of gene expression.
