Simple. The only organisms that survive are those that have the inherent instinct to reproduce. If an organism evolved that did NOT have the impetus to reproduce, it would have no offspring and thus it would become extinct. One way of looking at "higher" complex multicellular organisms like ourselves is that we were constructed (through evolution) by the cells that compose us as machines to insure their infinite reproduction. Being able to reproduce is one of the main defining features of being an "organism".

For once I would disagree with the highly informative Gray Bold. Sex is a by-product of reproduction, not the other way around. Early reproduction was probably mitosis and self-budding, as it still is amongst "lower" organisms. Mating by conjunction of genetic material from two separate individuals came later. The behavioral urges humans (and other animals) have to perform sexual intercourse are a species "fitness" advantage in that they encourage frequent reproduction. If sex was NOT enjoyable for humans and did not have secondary benefits like pair bonding and socialization, they would likely only do it for the express purpose of having offspring (true for some people). And if that were the case, many would choose not to since offspring are costly in time, money and effort to support and raise. With the modern availability of contraception, many people do choose intentionally to not reproduce.

But I suppose GB meant his statement in terms of humans -- in that case, procreation (pregnancy) does indeed tend to more often be a by-product of sex for recreation. We organisms reproduce because our instinctive nature tells us to do so, and in the case of humans who might reason NOT to do it, evolution has made the process so enjoyable that we do it whether we rationally want offspring or not. There are also evolutionarily acquired traits that make having children pleasurable -- parenthood can stimulate the release of hormones like oxytocin in both parents, creating an emotional bond with them that does benefit the parents. Social conditioning plays a part too -- there are societal "rewards" for having offspring in most cultures http://answers.yahoo.com/question/index?qid=20130220170254AAamWb5

Its a read but it should help you. =)

Answer 7

that did not help me at all

Answer 8

Since almost all living things have a finite lifespan, organisms reproduce to maintain the presence of the species. It is a biological imperative.

Answer 15

a sexual reproduction is where a boy meets a girl and he puts his penis in her and thats how reproduction works.

Answer 21

And to answer your question Asexual reproduction is when an organism can reproduce by itself without a sexual partner. For example Hydra Asexually reproduce by budding. The advantages of being A sexual are that you can be rouge and dont have to find a mate. Disadvantages are that you cannot get genetic drift and do not evolve quickly.

Sexual Reproduction is where a male and a female of a particular species mate using their respective reproductive organs. Advantages are huge amounts of evolutionary potential.
