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. ❋ Christopher O'Brien (2006)
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? ❋ Unknown (2009)
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. ❋ Unknown (2010)
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. ❋ Unknown (2010)
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. ❋ Unknown (2010)
Now why are professors fearful of offering that criticism of macroevolutionary theory? ❋ Unknown (2010)
In an earlier essay, I argued that the processes by which symbionts become organelles constitute macroevolutionary change. ❋ Unknown (2010)
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. ❋ Unknown (2010)
Morphofunctional saltations result in the arising of macromorphoses that can sometimes stimulate the beginning of macroevolutionary typogenesis. ❋ Unknown (2008)
In other words, this sort of macroevolutionary change can be studied as it occurs. ❋ Unknown (2010)
For this reason, but also because accompanying morphological differences can be quite considerable, evolutionary changes that involve transitioning between these states are macroevolutionary. ❋ Unknown (2010)
If I parse to "structural and functional abrupt phenomic changes result in (the arising of) large changes that can sometimes stimulate the beginning of macroevolutionary typogenesis" Ah! Typogenesis! ❋ Unknown (2008)
Integrating micro - and macroevolutionary processes in community ecology. ❋ Unknown (2009)
For example, the biodiversity of organisms is affected by macroevolutionary processes such as speciation and extinction that take place over long periods of time (evolutionary time). ❋ Unknown (2009)
In effect, your rejection of Brownback's microevolutionary approach runs more in line with your theory of constitutional change of partisan entrenchment, yet your macroevolutionary argument is much more in line with Ackerman's thesis of constitutional change through a constitutional moment. ❋ Unknown (2007)
The historical nature of macroevolutionary study involves inference from fossils and DNA rather than direct observation. ❋ Unknown (2007)
What is interesting, though, is that these modules, which we're used to seeing within the finer-grained process of development, also retain enough coherence and autonomy to be visible at the level of macroevolutionary change. ❋ Unknown (2009)
