Ok so interesting conversation today. Mind you, none of this was scientifically researched, but i just had to ask the CR people.

if you think about it, getting pregnant for humans is pretty hard. i mean with that fluid that kills sperm and what not, most the times the sperm never penetrate the egg. yet my friends dog humps another and bam theres puppies. so debate escalated to "is it an evolutionary trait or devolutionary? since the whole point for species is to procreate and pass the genes, why would the human body have precautions against pregnancy?"

and uhhm dont take into account birth control. again this wasnt really thoroughly researched so it was just from the top of the noggin.

and i guess this does qualify as idle, meaningless banter -_-

Well if it *is* meant to stop us breeding quickly...uh...its not working. There are around 6.5 billion humans. If it wants to stop growth nature is gonna have to do better. Like, massive natural disaster better.

What your talking about is, things in our diet are changing the reproductive system. that isn't anything to do with nature's control on the reproduction of the human species. there isn't such a thing called "devolution," once a life form has reached an evolved state theres no going back. but yes its true that the human race is slowing reproduction, but given the amount of livable space on the earth were overcrowding it already and not to mention the amount of pollution just one person makes in there whole lifetime.

Dogs only mate when the female in in heat, so it is guaranteed to produce a pregnancy. Humans mate at any time, irrespective of ovulation, so it is less likely to produce a pregnancy. Also, I think it has evolved that way because we have to devote more time to each child than any other species. We produce less kids (pregnancies) but invest more in each one.

If the human reproduction rate is any higher, society would be very very different from what we have today.

If you were to ask me why humans don't have "heats" I would say its from some evolution divergence of some monkey species, which we see some species of monkey see sex as a social activity.

But still, women have an ovulation period once every ~month or so, which lasts for 1 or 2 days* in which they have something like a %20ish* chance of getting pregnant. I can't remember but dogs have something like 2 heats a year*

Less chance of conception, but more times for a chance.
*=Not entirely sure. Take with a grain of salt.

I heard that women subconsciously tend to show much more skin percentually when they're close to there ovulation period.

Mmm , I think that ' fluid ' that can kill sperm cells protects the femal body from bacteria and such .
Sperm cells protect each other so that at least one of them will reach the egg . They squish
themselves together so the outside sperms are like ... a barrier to protect the sperms inside .
Like Jorlwind said , most women ovulate every month . If you don`t succeed , try again .

Because if she made a thread about it one of the wannabe-mods would've told her it was a duplicate and posted a link to this thread.
