Well hey back...
It is simplistic, yes. But it is a fact that hormones (particularly male hormones that in turn activate growth hormones) do make males larger in both species. I was simply making a statement about the physiology comparison, and I am not saying that they evolved this way for similar reasons, which they did not. But hormones are what make the difference in size between sexes in both humans and Cannabis. What in turn has driven the male hormones in these species is another discussion. You seem to want to delve into that on a grand scale. Well, I do not want to go down to the level of parallel evolution, quantum field theory and the theory of relativity to explain exactly why the universe is the way that it is in every post here. Life is too short for that. If I am too simplistic for you, so be it.
Or are you just picking a fight with me here over piddly BS? Seems people here like to do that. Especially the Aussies.
Theory of relativity?
Lol
Male insects don't always show sexual variation
The ones that do are often smaller.
Nor do many male fish show different size in sexes.
Birds don't always show difference in size between sexes.
Nor reptiles.
They all have sex hormones obviously
Nature isn't extravagant, if an animal is larger, it needs more energy and can die from undernutrition more easily.
Some animals show sexual dimorphism, but not as many as you may think.
Male canna is taller just cos it's a dude, like us, is pretty glib.
I replied to your post because, as I said before, it's just ridiculously simplistic, and I offered what I thought was a more reasonable cause for the canna male to be taller.
It's not to pick on you, lol, like everyone else out to get you, or whatever you reckon is going on.
I do think that male canna plants are taller to spread pollen more efficiently to the shorter femmes, though.
