But make no mistake: the mechanism he offers still relies on random genetic changes in homeobox genes controlling development, not accumulated small mutations over time that result in "macroevolutionary" changes.

Does it also seem odd to you that in a single laboratory goof-up we were able to to witness in just 5 days the macroevolutionary event which you claim took billions of years to accomplish in the wild?
-
Which brings me to another matter, a line of experimentation that shows yet another case whereby macroevolutionary change can be studied by direct experimentation, almost in real time.
-
Thus, it stands to reason that studying the means by these characteristics evolve amounts to experimental analysis of macroevolution, and understanding the underlying mechanisms constitutes an explanation of macroevolutionary processes.
-
The bottom line that is in keeping with the title of the essay - not only can this particular macroevolutionary process be studied experimentally, it can be understood and the corresponding macroevolutionary process recapitulated in a controlled setting.
-
In other words, this sort of macroevolutionary change can be studied as it occurs.
-
Now why are professors fearful of offering that criticism of macroevolutionary theory?

-
The bottom line is simple, though - macroevolutionary changes involving gene migration can be studied in real time, once again putting the lie to the ID/antievolutionist assertion that macroevolution cannot be addressed experimentally.
-
For this reason, but also because accompanying morphological differences can be quite considerable, evolutionary changes that involve transitioning between these states are macroevolutionary.
