Increased size is not the ONLY way to improve offspring survival. QUOTE
It isn't the only but primary way. QUOTE//////////
i wonder what makes you think it is the primary way. if it were then surely all organisms would concentrate on having a few large offspring, would they not?
Every organism has a complex strategy, and size is only one factor.
Your right, it isn't the primary way and i do not know how to measure it anyway but being big and strong definitely helps the species and offspring survive.
I never said "always" but generally being bigger is better.QUOTE///////////////////
hespera sez.
We will have a hard time defining "better" in any way except in terms of survival success, reproductive success. The house rat is a way "better " design than the rhino, whale, moose etc. Way way more successful, and way more likely to still be around ten milion years from now.
The percent of really large animals is so small that it is almost freakish for animals to get big.

H sez...
it definitely helps with some organisms by no means all or most.
I wouldn't see why.
Although, in some species (such as the Southern Flying Squirrel), larger females aids the females in defending territories with food and nests. Males of that species, on the other hand, are smaller and non-territorial. Some bat species also have larger females, probably due to an increased wing size being beneficial to carrying fetuses (especially large fetuses).
So, as you can see, there are many different reasons why the females of specific species might be larger than the males.
Does this work across the board with all species? Of course not, but each species has dimorphism (or lack thereof) that is apparently beneficial to that specific species' niche and evolutionary development along with sexual selection in many cases.
Hope that makes sense

Well Ke, did you get anything from this? Does sexual dimorphism seem inexpicable in terms of evolution? or do you see some ways that it makes sense?
I am still confused about sexual dimorphism.
I really cannot fathom how different species (no matter what the enviornment is) produces differences in the sexes. While i understand the different roles of the sexes, I do not understand why some female species are bigger.

I believe all the big cats (excluding the lion) do not apply to this concept yet the female is smaller.
This also applies to all bear species.
Why wouldn't this concept apply to them?
Interestingly, lionesses can be in groups as large as 25 yet they will allow 2 males to come in and kill their young.

What concept? I explained more than one
