A beekeeper here.

1. Bees have only been kept in flat frames for less than 200 years which would not be enough time to select for such a specific trait.

2. Domestic bees that swarm and find homes in hollow trees or gaps in houses form blobby swirls of what beekeepers call 'crazy comb'. The liberated bees create topological forms which are probably much more efficient than flat frames. Flat frames benefit the beekeeper, not so much the bees, and bees will make comb when and where they like.

I believe this to be an incorrect statement.

Evolution in insects is working on a much tighter time-frame, for example: https://www.smithsonianmag.com/smart-news/new-evidence-peppe...

Also there are plenty of "beekeepers" who believe in shorter time frame adaptions, and are providing evolutionary cradles for such, e.g. https://www.apisarborea.org/

And of course many stories with anecdotal evidence from communities of bees in protected watersheds evolving (or perhaps activating prior) varroa mite resistant traits.

200 years is more than enough to select for something, even with natural selection, and especially so for artificial selection. Dog breeders can and did select for many specific traits in the course of single lifetime, for example.
