The gene traffics between the sex chromosomes and autosomes are a widely observed pattern of new gene evolution

in mammals and insects.   Through extensive discussion and efforts made about the possible mechanisms involved,

progresses have been made in understanding the evolutionary forces operating on the process.  However, most proposed

models were able to explain only one or a few facets of the gene traffics in only one or a few species.  Is the pattern

of new gene evolution formed by different mechanisms or is it shaped by the same force of evolution?  The reported gene

traffics in various organisms will be analyzed and compared for seeking an evolutionary force in common that is operating

on these organisms.
