Male & Female

How, exactly would "self-generation" work?

What have you been smoking?

Sounds like a Hermaphrodites, which is an an organism that has both male and female reproductive organs.

Some examples:
Banana slugs, Snails, Some fish species, Tunicates, mollusks, and earthworms, Bryozoans (moss animals), trematodes (flukes), and barnacles.

I mean no sex type, only one type able to give birth .

You didn't answer my second question.

Between female and male only the female is able to give birth. So your wish became true already!

<...All...>

Nonsense: http://en.wikipedia.org/wiki/Earthworm

I mean same as the female fish does but with no fertilization for it eggs by male --- I think the life had beed much better ! Is n't ?

I mean with no sex organs at all -- Why sex ?

Where's the fun in that?

Why all the alive creatures consist of males and females ?

The genders only apply to sexual reproduction. Asexual reprodution exists in single celled organisms which are bona fide "alive creatures."

I think you are a bit of a whackadoodle for asking this.

I mean self reproduction with no sex , no male or female ,no organic sex, why the sex ?

What does a whackadoodle do?

Have a look in Wikipedia. There's plenty to read there.

It would be unwise to look elsewhere on the web.

There used to be asexuals, but they all died from boredom...I think it has something to do with evolution...that's how arm wrestling got started...

There are species that do that, and not only the salamander.

Sex is a very efficient evolutive tool, God splitted many species in two genders, let them run thru the toughness of life and then re-combine the two better adapted individuals to make the species thrive.

Well, Male and Female are the family leaders, two better than one, they help each other.

@Marzoky...

Well, in the case of the fish, the male's job is only to fertilize the eggs and never show up again . does not help the female fish .

Aso in case of the "spider", the female kills the male just after the fertilization process and eat him - the male does not help the family other than giving his body as a food for the female to eat.

clearly an engineering question, unfortunately I didn't take "goofball questions101 in school

@Fredski....

If you have no answer , simlpy say I do not know- No need for complicated reply.

I do not know and you will not get the real answer on a forum (especially this one ) - ask God.

Look up 'parthenogenesis' - the biological term. (The version by 'Canned Heat' is interesting, too.)

Scientifically, there is really one one answer to why two different sexes exist: Evolution. In terms of millions of years of survival of every species, a 2-sex biology was much more successful at surviving climate changes, diseases, and predators than single-sex biology.

The proof of this is what you've pointed out: the vast majorities of most species are 2-sex.

That is not the answer, it is much easier to survive if there is no 2-sex biology.... no need for partner to survive.

My answer IS the correct answer. Nature proves you wrong. If one-sex biology were better ('easier to survive'), then that would dominate our planet. It doesn't. One-sex biology is a tiny fraction of what occurs in nature, existing only in unusual circumstances.

Admit you're wrong and then go away.

Asexual reproduction exists throughout the plant and animal species of the world...These methods include:

fission(biological)

budding

vegetative propogation

Spore formation

Fragmentation

Agamogenesis

Parthenogenesis

Apomixis and nuceller embryony

There is also heterogamy which is an organism that can reproduce with or without a sexual partner....

http://en.wikipedia.org/wiki/Asexual_reproduction

In the case of single celled organisms, genetic diversity is provided by their high mutation rate, (sloppy self-copy!) which they are able to carry without lethal consequences because they are such simple organisms. Sex is not needed because there is another source of genetic diversity.

For more complex organisms, asexual reproduction of exact copies places the species at higher risk of extinction, since entire populations could be wiped out by a single cause to which they are all genetically susceptible. Possible causes include environmental conditions which are not tolerated (high UV, acid rain, volcanic gases, a cold winter etc etc), disease susceptibility whether bacterial or viral, and so on.

Did you never take biology in school?

Try an internet search of "genetic diversity" for more information as to why it is important.

To survive , it is much easier for a creature to survive by himself than a need for a partner for that......On the other hand I consider ( what is called) evolution theory a myth and not more than a myth.

Well, if the evolution theory in not proved yet, and could be myth and even a big lie , why they teach it in the school ?

Marzoky, are you behind that thread then?

Well then it is going to be very difficult to discuss anything with you if you don't understand evolution theory enough to believe it. It is a well-proven key scientific proof that needs to be understood in conjunction with "genetic diversity" to answer your questions.

Its like trying to answer a math question where you don't understand what the operator <= means. Sure we could answer the question in some convoluted way without using it, but why should we waste our time trying.

Why do you think evolution theory is a myth, and just so you know, a religious answer is not going to work as it is contradictory to your question.

Evolution theory states that Man's origion is monkey - That is for sure is a myth... and I insist it myth and deception.

Listen Jack of all trades, I believe in Andrea Russi's E-Cats Cold Fusion Reactor and don't believe in the Evolution theory.

(comment deleted)

"... I consider ( what is called) evolution theory a myth and not more than a myth."

Okay, let's run with that for the time being.

There must be some Creator involved in your belief... Some supreme diety or another, or maybe an intellegent designer.

Are you telling us that this powerful entity, the Creator, has made a mistake?

In this forum we discuss science and technology topics. Not supernatural stuff.

The scientific answer is evolution. It you want a different answer - you don't believe in evolution, perhaps you believe in some form of creation requiring a supernatural being - well by definition that not a natural answer. You're in the wrong forum. Go to Yahoo Answers; I'm sure the teenage girls who hang out there will give you the answer you want.

I didn't get into it (for obvious reasons), but the religious argument also supports dual sex more than single sex (at least western religions). <cough> Book of Genesis for example <cough>.

That is my personal opinion only, but still supports the scientific explanations offered regarding why dual sex is better and far, far, far more common on this little world of ours. It doesn't happen often when both support one another.

Well I think that does it for this question thread.

Seriously? Why do you think engineers would have an answer to that question? Did you try the biology forum two doors down? Or better yet the genetics forum around the corner. They'll be able to give you an in depth answer to your question.

Engineers, not so likely.

I'm guessing that you either never took a biology course or you are doing an uncontrolled study on the responses of engineers to whackadoodle questions.

You should have referred AP #1 to the Psych Ward.
