This is what Wikipedia (admittedly not the fount of all wisdom!) had to say:
The term 'microevolution' has recently become popular among the
anti-evolution movement, and in particular among young Earth
creationists. The claim that microevolution is qualitatively different
from macroevolution is fallacious as the main difference between the
two processes is that one occurs within a few generations, whilst the
other is seen to occur over thousands of years (ie. a quantitative
difference). Essentially they describe the same process.
The attempt to differentiate between microevolution and macroevolution
is considered to have no scientific basis by any mainstream scientific
organization, including the American Association for the Advancement
of Science.[2]
---- (The link Wikipedia gives doesn't lead to any AAAS statement making that assertion, however). My point was that YECs argue that microevolution can occur _within_ a "created kind", so, apparently only one species of say dog-kind could be taken on the ark, and mircoevolution since the flood could account for all the various dog-kinds. What they refuse to accept is that given sufficient time, different species emerge from a common ancestor, so that they can't interbreed (as, I believe, most dogs can). I felt that the definition given from your book wasn't sufficiently clear to distinguish it from the YEC interpretation (variation within a kind).
