I was also thinking about the mixing of gender traits in the context of ideas about evolution.
From what I have read, intersex is a "disorder" -not a mutation -but other species are considered to be "normally" hermaphroditic, and would have developed as such by evolution if current ideas are correct.
Could such things happen to humans by random mutation?
I can't think of any reason why it could not. They are, after all, random. Just like we might conceivably evolve back into, say, Oviparous beings given enough of a consistent selective pressure and enough generations to mutate into such a role.
If humans are expected to continue to evolve, how do we think it could affect human sexuality -or anything else?
Human beings are certainly not exempt from biological evolution, but that is not really a major consideration; we are simply not very cooperative with it, nor is there a compelling argument why we should try to.
Evolution is all about natural selection of the most adapted. It is not human, certainly not by the moral conceptions of the word.
Maybe you mean to ask whether we are "meant" to evolve in "that direction"? Nope. Nor in any other, really. Evolution isn't a matter of growing in "worth", just of better adapting to environments.
Are we to expect man to eventually become a very different species
If we survive long enough and do not choose to genetically engineer ourselves out of natural evolution, it is a given that we will.
-that man's 'tree' will eventually branch off into many very different species due to evolution?
Barring intentional intervention or dying out of the branches, then yes, that is bound to happen. But it will take quite a few generations for the effects to result in full speciation.
This is actually the first time I have thought about that. When I have considered man's possible futures, I have always thought of man continuing as the current species.
Whoah
I take it that you dislike the idea? There is really not much of an obvious reason to.
I don't actually believe this will happen for a number of reasons, but
it does raise questions of perspective concerning sexuality.
What do we perceive to be abnormal -and what do we perceive to be a process of evolution? Should intersex be prevented if possible -or allowed as a natural evolutionary process if it ever occurred as such?
It seems to me that we have no good biological or ethical reason to oppose the natural development of intersexuality, homosexuality or transexuality. They are simply not issues from a perspective of species survival, which is what evolution is all about.
Also, please notice that much of what we consider ethical is in fact at odds with biological evolution. Evolution does not have a purpose as such, much less a fair or wise one. It is just selective, often in a cruel way.
What might this say about the physiology of people who feel they were "born this way" in the case of homosexuals -or people who feel as if they are one sex in the body of another?
That they are not "meant" to be, not anymore than, say, any given color or amount of hair is. Sexuality is in part genetic, in part hormonal, in part a result of the social environment.
But if there is some sort of meaningful interaction of it with biological evolution, I am just not seeing it.
One might perhaps argue that homosexuality, intersexuality and transexuality are adaptations that improve the social environment by making demographic pressures less serious, but that seems quite speculative and ultimately irrelevant to me - humanity is neither likely nor advised to make a point of "encouraging" adaptability over other, more social and ecological considerations.
Not making any statement here -just thinking
