Hey, in the 50s they were just beginning to wonder if continents drifted.
Biological evolution is never just defined as a change in gene frequency. (At least, not by actual experts.) This is because you can change the hell out of all kinds of genes' frequencies and never change the population at the species level.
The real problem is when these things are taught at the highschool or even basic survey course level, the concepts are explained by the "just-so" story. People talk about it as if some one single gene is changed somehow to make rabbits furrier in cold. This is why Creationists cannot get macroevolution and hardly anyone can explain it properly. Because you have to go back and fix all kinds of wrong concepts, like, "selection acts on genes." No. It doesn't. Selection acts, and can only act, on individuals. The result of selection, in some cases, is a change in the gene frequency in a population, which is not the same as a species, obviously. A change in gene frequency does not equal biological evolution, although, I believe, and many others have come to believe, we will be able to find a steady % of change that we can use to finally and precisely define a "species." BUT - even that will probably not be relegated to just genes, but also to other forms of genetic material that make up the chromosome that we don't label as a "gene" in the classic sense.
I don't care if people misunderstand. They have to, unless they spend six-eight years in school learning this stuff. What I care about is someone acting like other people are stupid for questioning the story when the story is so inadequate and the "experts" acting like the questioners are idiots, mostly have no clue what they are talking about, anyway.
Everyone needs to shut the hell up with their "expertise" in this field and just listen to one another and see if they can explain to themselves, even, why they decided to believe what they believe.
If I treat them like they are stupid, it's because they really should know how it feels and because - well - I actually
do know what I'm talking about. When someone else around here shows up with more years of study and work in the field than myself, especially more recent work, I will happily defer.
Until then, the only person even close to a true expert here - is myself. And tell you the truth, God is way more interesting to me to chat about.
(BTW - Watson/Crick didn't even announce they had the structure of DNA until the early 50s - and no one was talking about gene frequencies in biological evolution, afaik)
