3.11 was WfW, and ran on top of DOS just like 3.1 did.
NT 3.51 used the NT kernel, and (mostly) looked like 3.1/3.11 on the surface. NT 4 used the NT kernel, and (mostly) looked like Win95.
Win 95/98/Me also ran on DOS, though it was more tightly integrated than it was in the 3.1 days.
Win 2k and everything after was based on NT.
Interesting bee fact -
In a hive that has been queenless for a period of time (long enough that there’s no way they can raise a replacement queen), one or more workers may develop the ability to lay unfertilized eggs.
Due to how honeybee genetics work, those unfertilized eggs can hatch into drones (males), which may then have the opportunity to mate with queens from nearby colonies.
I guess this is sort of a last ditch effort to propagate the hive’s genetic material before it fizzles out and dies. Which I think is fascinating.
