The phenylacetic acid (PhAc) degradation pathway becomes an interesting model for the catabolism of aromatic compounds. To determine the molecular basis for this environmentally important process, we did a phylogenic analysis based on the PhAc CoA ligase gene. It suggests that the PhAc CoA ligase genes are distributing widely and subject to frequent lateral gene transfer within and across bacte...

In cognitive systems, one often distinguishes between phylogeny and ontogeny. Phylogeny refers to the initial configuration of the system and its evolution from generation to generation. On the other hand, ontogeny refers to the learning and development of a given system during its lifetime. The issue that arises in this context is the requirements for the minimal architecture for a cognitive v...
