"Which female animals do not signal, in ANY way, that they are fertile?"
Well rabbits don't. That is just off the top of my head. No physical symbol of being ready to mate as they are induced ovulators.
Vervet monkeys have concealed ovulation like human females. Quite a few primates other than humans do.
Also you get amphibian species where the male just lays the sperm on the ground to be picked up by the female. So no need for female mating signals there.
"everything about the male body is biologically "logical""
Like a prostate that does very little but has a high propensity for becoming cancerous and killing you? That doesn't seem logical to me. It could be the worst organ male's have and one of the worst of any animal for that matter. Some logic...
Thanks for your reply, you have given me some things to consider.
I think the rabbit example actually intensifies my argument, as not only do human females have concealed ovulation they also do not have induced ovulation. Induced ovulation must be the natural "solution" against not showing signs of fertility. So why do humans have both concealed ovulation AND do not have induced ovulation? That makes no sense biologically.
I'll have to get back to you on the rest after I think about it.
The prostate...I looked up information on the function of the prostate and I'd hardly say it does very little! It's vital to reproduction!
Prostate cancer almost exclusively affects elderly men only. I'd conclude that the prostate isn't "bad" in itself but that our longer lifespan is "at fault" here.
I wasn't aware that many female primates had concealed ovulation. I thought it was semi concealed for some or not at all concealed in others. I'm still looking into this but thanks for bringing it up.
"function of the prostate and I'd hardly say it does very little! It's vital to reproduction!"
Where do you get this stuff? The prostatic secretion slightly increases the lifespan of sperm by reducing alkalinity in the vagina. I'd take a less than 1% reduction in sperm quality to not have that cancer time bomb. Prostate cancer is the leading cause of cancer death in men in the UK and second in the United States.
"our longer lifespan is "at fault" here."
Well that is true of many cancers. The presence of the prostate puts a hard limit on the life span men can have. Since it is almost certain to become cancerous just some men die before that can happen.
But it also controls urine flow and propels ejaculate. I was unable to find a source citing exactly how essential prostatic fluid is to sperm in terms of reproductive advantage. This information was either left out completely or not specified but its importance was implied as great in those sources that did mention it.
I still wouldn't say the prostate itself is either minor or inherently flawed.
"But it also controls urine flow"
No, that urine flow is controlled by the bladder wall muscles and sphincter. The prostate sometimes grow so large to prevent or limit urination but that is a process of its size pushing the urinary tract closed again due to it's inherent flaws. In a healthy male the prostate has no impact on urine flow.
"propels ejaculate"
No, that is muscles at the base of the penis. Their are men alive today without a prostate (due to cancer removal) that still ejaculate.
Seriously, I'm not trying to be rude, but are you making this up as you go along?
Yes, it propels ejaculate. It's not the only part that does, but it certainly does.
Well this has gone off track. Unless you're going to keep it on topic and answer the main points then don't bother. I gave a good answer to your prostate complaint which you have failed to really address, instead picking apart my choice of words and shit.
I should rephrase that. Inherently is the wrong word since the potential for cancer is itself inherent to the organ (as would be true with all types of cancer)...I'm trying to think of a better phrasing...
I guess...what I am saying is you're talking about the prostate as if it's the appendix. But the prostate has definite purpose, even though it can kill you...however it virtually never kills anyone prior to its logical life expectancy. There's nothing particulary illogical about the prostate or prostate cancer.
Are women more evolved biologically than men?

P.S. Rabbits don't go into heat but they do show signs of being receptive.
