I mentioned Endor; my mistake, it should have been Endler; but at the time didn’t have access to the reference, so here it is now;
You can also look up the term on Wikipedia to find “Microevolution is the change in allele frequencies that occurs over time within a population.” and “… it was not until Russian Entomologist Yuri Filipchenko used the terms “macroevolution” and “microevolution” in 1927 in his German language work, Variabilität und Variation, that it attained its modern usage. The term was later brought into the English-speaking world by Theodosius Dobzhansky in his book Genetics and the Origin of Species (1937).”
Both Filipchenko and Dobzhansky are evolutionists so you can blame them for the use the terms. Creationists had nothing to do with it.
Not in my experience. I have done two certificate level MOOCs run by universities and both used the terms micro- and macroevolution. The terms are used on the Berkley Evolution 101 site. The chief problem with the terms is that they are loosely defined and as a result many Creationists prefer to not use the terms either.
And no, I don’t accept that ““Microevolution” is the exact same process as “macroevolution,” just with a smaller window of time in focus.”
All this is getting quite off topic so I won’t discuss it any further in this thread but am willing to do so in a different more appropriate thread.
