Why organisms reproduce?

When it reaches a critical potential energy, sort of the top of an energy hill, it begins to slide down the other side resulting in two at the bottom of the energy valley. These then start their climb until they reach the top of a new energy hill, etc..

That basically means that cell reproduction is a characteristic itself, deoesn't it? But my question is slightly different.
And your last post was off topic according to me.
If I didn't underatand it properly, then please clarify.

I've never reproduced. Peer pressure and nagging parents who want more grandchildren?

I'd imagine all the early organisms that liked to be bachelors died off and it's just the mutants who could reproduce that did so. I guess that's why sex is such a big thing now.

I don't think the genes have a will of their own. They just do their thing like good little programmed nanobots. I don't think genes feel joy when their host organism finds a snack or gets lucky. The organism as a whole though, it's in every creature's instinct to do it now.

I also want to know initially actually how did the first program of reproduction formed. I just believe it was out of mutation, but I think the mutation must have happened before the initial beings die out, and we know they were very simple beings which couldn't live long. So if they didn't get the ability of reproduction they had to pay the expectation to next generation, but the next generation would be different form them and their birth have to rely on chance of nature. That would be a long long period. Periods by periods finally the generation which was able to reproduce was born and survived. Wasn't the initial evolution of reproduction so aimlessly?

We don't really "know" anything conclusively regarding biogenesis or abiogenesis.

So if they didn't get the ability of reproduction they had to pay the expectation to next generation,

How is there a "next generation" without reproduction?

Periods by periods finally the generation which was able to reproduce was born and survived.

In trying to reason this statement, I find only paradox. Perhaps you can rephrase it punchingsack?

Why would the initial evolution of reproduction be aimless? It's an interesting idea, but it needs some support.

First of all, I'm sorry for my poor English expression.....

So a generation has to be from reproduction..... I get it. Then I meant upcoming , new beings.

An extremely long word passed, finally the new beings which was able to reproduce was born and reproduced their generations successfully. Their descendants continued and evolved.

That's just in my opinion. Since mutating is so random, would there be an aim in randomness? I think the purposeful selection by beings themselves based on natural selection didn't begin until the ability of reproduction invented.

Dear Mohit, I think your question is framed wrongly, consciusly or unconciously!

First of all, Let us ask, Do all biological organisms reproduce?

The obvious answer is no, there are plenty of examples of organisms that do not reproduce, may be not of an entire species!

The next question would be, Why do all members of a species that are capable of reproducing reproduce?

This is a bit tricky. There are of course many human beings who are perfectly capable of producing offsprings, but have chosen not to! Thus to exercise the choice of reproducing by those organisms that have it, has reasons beyond biology or chemistry.

Am I correct?

I think egg came first and egg came from an organism which had resemblance to the chicken species. Moreover it means that small variations(changes) in DNA resulted in the formation of chicken species. So that change will first occur in the egg.

Good discussion is going on. I think we have overlooked this post. Do you think it is correct?

[learnin to learn]

Hold on, Are you giving the example; at first there was an organism that resembled a chicken and ofter years of adaptation and genetic variation the chiken that we know of today was developed?

No worries.

Did you look at the link I posted about biogenesis?

An extremely long word passed, finally the new beings which was able to reproduce was born and reproduced their generations successfully. Their descendants continued and evolved.

It sounds like you are stating that reproduction is a byproduct of mutation. Is this what you mean?

That's just in my opinion. Since mutating is so random, would there be an aim in randomness? I think the purposeful selection by beings themselves based on natural selection didn't begin until the ability of reproduction invented.

While we encourage all our members to form their own opinions on topics, we also ask that opinions are backed up with supporting evidence. For example, your response quoted above would be more compelling if phrased in a way similar to this:

Because the definition of natural selection requires reproduction, it follows that natural selection did not begin until after reproduction existed.

Natural selection - Wikipedia, the free encyclopedia

Because I believe that reproduction was a byproduct of a de novo mutation, and mutations are mainly random, then I conclude that there was no aim in the advent of reproduction.

A response such as this gives the reader the opportunity to follow the links that back up your claims.

Organisms reproduce BECAUSE their genes tell them to.The question is how, why and when do the genes cause this phenomenon? What else can be said on this subject? If something is not known, then the answer is... it is not known.
