How about the evolution of a Mudcat thread?

I have no idea how a couple of the last posters in this thread got the idea of talking about song researchers as "Nazis." I mentioned WWII and Nazism in my comment and then you just go free association with the term??

Bartok was not an ethnomusicologist.
There have been folklorists who deal with songs. They are not ethnomusicologists.
My posts explain how ethnomusicology developed after WW2.
None of this stuff is static; what people were doing in 1950s vs.today, and vs. anything before that that you might presume to call an antecedent to ethnomusicology, is vastly different. Likewise Biology.

I had only made the point that if one is using the language of "evolution," one is not speaking the language of ethnomusicology, which roundly banished the term in the 1950s.
In the 1960s-70s, some people found it glamorous, for some puzzling reason, to link themselves to the term "ethnomusicology" without actually practicing it, but rather presuming that if one did anything -- studying, playing, recording -- with any music outside Western art music and commercial popular music then somehow you were "ethno" (lol).

As I've mentioned many times on this forum as well, ethnomusicologists also tend to avoid the term "folk," except when referring specifically to a a cultural group may use that term.
Plenty o hucksters out there who hope some of the academic quality of the term "ethnomusicology" will rub off on them. Oh the irony—if they were actually ethnomusicologists, they'd probably be wanted to distance themselves from that term and from academic artifice.
