Every animal has to reproduce. That's what their lot in life is. That is also how evolution occurs. Humans I don't believe will ever go any farther than they have. We are not strong like other animals on this planet. In fact, if it hadn't have been for us building civilizations, we would have become extinct a long time ago. We almost became extinct with the Tambora eruption some 10,000 years ago. There were only 70 living humans once the eruption was over and settled.
Anyway, someone on the SE forum brought up something about the future of sexual organs and our body's built-in outlets (for urinating and dumping). I must say I have never really considered a thing like that. But one thing about my mammals of the Metazoic, you will notice that NONE of them have an external penis or scrotum like today's mammals do. That's because they don't exist in these animals. The females have the same structures as they do today. In the males, the testicles and penis have moved inside the body and cannot be found externally. Much like a lot of the young of today's mammals. This makes the animals more streamlined for running. Either running from predators or running after mates. That's why the mammals of tomorrow will be much faster than the mammals of today. I would think a huge scrotum on a male would make quite an obstacle when moving. Ever seen the nads of some domestic pigs and horses?? Whoosh!! How they can move with those at all makes me wonder. But the pigs and horses of my Metazoic World do not have these features externally. In the males of most mammals of the Metazoic, there are still 2 vents, but there is no external indication which are males and which are females.
The Trelatebrates however, are another story. They are the ultimate in evolution as far as this goes. The Trelatebrates are strictly a Metazoic order, one I myself made that includes the Therapeds, Deinognathids, gaboon-antelopes (soon to come), Immanids (soon to come), Cerots, Anacolls, "Double-grazers" (soon to come) and Shrubucks. Anyway, both the males and females have actually 3 ventral outlets. All female mammals have this feature, but the males in these families also have a small opening in the front-pelvic area for the penis to come out. The testes are situated far inside the pelvic cavity, much like the females' ovaries. They also have a small opening in the central pelvic area for urinating. And the anal opening at the underside base of the tail for, well, you know what! LOL! Anyway, that is why I call this order "trelatebrates", meaning "3 vents". If these mammals were around today, they would be impossible to sex without maybe DNA-sexing used today in birds. Or watching which one of them is humping the other during breeding season.
Anyway, the post was unique, and interesting. It was an interesting thought anyway. One I myself might never have brought up. Either I wouldn't have been clever enough to think of it or too embarrassed!! Some people take talking about animals' sexual organs and ventral openings as an indication of beastiality!! But as an evolutionist looking at it from that kind of a POV, I guess it just has to come up sometime!!
