Abstract
The event of speciation, the establishment of definitive genetic isolation between sister populations, remains the “black box” of genetics, and by extension of the systematic sciences. What we know about this event serves principally to underline how difficult it is to know whether definitive genetic disruption between closely related populations has actually occurred. It is fairly well agreed that in mammals speciation appears to require the physical division of a parental population. But the genetic mechanisms underlying such events may take place on one or more of many different genomic levels, gross karyotypic and below. Moreover, speciation is not simply a passive correlate of morphological differentiation: Speciation corresponds to no specifiable degree of morphological shift.
