Why do humans copulate in private while the other animals do it in public?

Humans have a higher brain function and can make choices.  Animals are just animals and don't stop to think about where they should do it, they just do it.

A - because they are the same species and therfore have the same number of chromosomes, which means they can breed together.  homosapiens and chimpanzees are quite closly related but have different number of chromosomes so they cannot mate.  if they did manage to mate the offspring would be infertile, a bit like the liger, which is the offspring of a lion and a tiger.  chimps and humans have approx 97% of the same genes!!

The animal kingdom doesn't have bias and lables like the human animal. If one actually finds attraction to the same sex, it is most likely a scent confusion. Most animals do their business based on scent.\n\nLearn all about spiders below.

This is often thought of as heplful in the mating process. It gives a "target" of sorts. Kind of the same idea as baboon butts.

OK, long story here.\n\nI used to raise pigs for 4H, and we had a boar that we used to breed the females. One day when I was out feeding, his "cork screw" came out of his sheath, and he started humping the air. No females were present so I have no idea what was going on besides masturbation, and yes he did ejaculate. I remeber it like it was yesterday... I have been scarred for life.\n\nActually haider, dolphins also have sex for pleasure, and some pymie monkeys do it as a way to greet/recognize each other.... discovery channel.

I would like to answer the question in a grown up fashion because this is a natural situation.  I would think that if 2 of any people are engaged in sexual conduct, they are likely to indulge in the behavior in a mutually desirable action.  I don't think that they are doing whatever because they like nipples or penises.  I image they are doing it out of desire, for erotication, and pleasure.  They probably touch more than those two body parts mentioned above:  like kissing, massaging, caressing, anticipating, and HEAVY BREATHING!  Leave these folk alone.  Stop wondering. You might just be wrong.

Penis is the male organ of copulation and urination in mammals.

I will give you a couple but you need to look up the rest.\n\n2 reasons zoos use artificial insemination. 1) usually a zoo will have very closely related animals in a collection, often parent and offspring or siblings.  To reduce inbreeding they will get semen from outside sources to impregnate resident females.  2) usually a zoo environment is not conducive for romance between an animal pair.  This problem is circumvented by using artificial insemination so the female can become pregnant without having to go through the courting rituals.\n\nArtificial or in vitro fertilization is used for humans for two major reasons.  1) low sperm count on the part of the males can be compensated for by specifically introducing donated sperm to the egg.  2) Damaged or obstructed fallopian tubes can be circumvented using in vitro fertilization where the egg and sperm are joined in a petri dish and the fertilized egg is returned to the uterus.\n\nFinally risk of passing a genetic disease to offspring is a matter of simple math.  For the donor that carries a dominant trait for a given disease, there will be a certainty of passing on the condition.  For the donor that carries a recessive trait for a disease there are the odds of joining with a mate that also carries the recessive gene for the trait.  Then there are the odds of both parents passing that recessive gene to the offspring.  \nNow the rest are up to you, unless someone out there lets you off easy and answers the rest.

i would say that is pretty much on instinct level men like them beause they are forbidden to see in public and they represent sex.  the breasts look like the behind which is what the male sees during sex primordially speaking.  Humans are the only animals that copulate face to face.

Our understanding of the emotion love is limited.  I do not believe that animals can fall in love with people in the traditional sense of the word.  Animals can have an affection for people, but our understanding of that affection is questionable at best.

Well all animals attract the opposite sex by the female of the species coming on heat.This function allows the female to attract the male over a wide area.Usually a dominant male breeds most of the females,this ensures that the resulting offspring are strong and healthy

Chickens do not have sex like humans do. The egg is ferlized when the rooster sits on it and deposits the semen on the egg.

freaks.\n\nwell, honestly, I'm not sure what the people are called...but the act of having sex with animals is called beastiality.

All animals release pheromones, or perfumes, that attract others, show dominance, etc. So insects attract others this way and then mate. While the fertilization is the same, the mating process is different for many insects. However, many times the female may eat the male.

sex is an animal instinct.... some people don't care how they get it as long as they get it. They block all emotion out of it. The people who have sex only for love just have to accept that not everyone out there is like them. People actually do have sex for the act of it alone, and not for love and commmitment.

Monkeys and apes have sex all the time for pleasure alone. The Bonobos are the "worst" if you want to call it that. (Bonobos are the smaller of the two chimpanzee species)\nBonobos have sex face to face like humans, have sex for food, have sex to settle arguments, have sex to get to know each other, etc.etc. Two females frequently rub their genitals together just for fun and pleasure. Pedophyllia and homosexuality are completely accepted and are quite common among Bonobos. Some scientists have speculated that the human-chimpanzee common ancestor was more like bonobos than the common chimpanzee for a variety of reasons some of which are sexual.\n(By the way, the word is "wondered", not "wandered")

Actually no. They are the most laid back animals. Just like bunnies hate to reproduce. They just have alot of kids at once. They don't sit around having sex all the time.
