If all living organisms came from a simple cell than how did it survive if it did not had previous genetic?

Question

Rephrase:If all living organisms came from a simple cell than how did it survive if it did not had previous genetic?
I'm asking it again because I only received questions "after the survival."I'm asking what made them survive?

Previous Genetic Information

You see, natural selection was not able to work if there where no genes to choose from. If did not had the dominant genes than it wouldn't survive.

Lets say a simple organism such as a Prokaryote, how did it manage to survive? Please do not offend because I'm not offending you.

Wow, if you don't have any genetic information than you wouldn't be what you are. You would probably be death.

All organisms need genetic variation. You would probably know what would happen if we didn't had any genetic info. or variation.

Answer 1

it all comes back to creation or evolution. according to your statement evolution could not work,so God must have created them. does that sound reasonable?

Answer 2

The process by which the first proteins became organisms isn't known, there are theories but none can be proven at this point. Likely, there were many cellular developements, however, the one with the ability to replicate would have been the ancestor to life on earth. Essentially, this is evolution in action, and a certain amount of that is luck. Reproduction on the cellular level would provide for future genetic variance. Initially, there would have likely only been one "organism" for lack of a better word. Random chance probably lead to multiple different variations, none of which were capable of surviving long term or were unable to replicate, based on this idea, all life on earth didn't necessarily come from the first life on earth... it may have come from a later "chance" of life, while others failed.

Oh, and for Desperado: Primitive cells don't require a mate... they merely consume "building blocks" and replicate themselves. Genetic variance would occur after generations of mutations or small variations resulted in new lifeforms. Asexual replication.

Answer 3

Ah, you've missed a point here.... the amino acids existed, as they are a product of elements(right off of the periodic table) and electricity (in abuldance on this planet in its early history......(google: Urey, mars jars) remember, for life to evolve, it only has to be successful once... if one gene can be formed, and it replicate just once, even if the odds were billions to one, remember, it only had to happen once, and it had 6 billion years to do it just once..... From there, it's easy.... if the organism is successful, it survives, if it is not, it dies. You are thinking that evolution is like a wind can come thru an airplane parts storage yard, and put together a 747 --- from just a bunch of scattered parts, to a 747. And that, of course is a stretch, and where lots of people get hung up......

But, if you consider that the wheel was invented, then the screw-driver then kids 4 thousand years ago played with kites, yadadya, then propellers with a drive chain, the first who put together the airplane were a couple of bicycle guys -- the Wright brothers.. It of course wasn't a very successful plane, and for sure looks nothing like a 747, but the evolution is there... then it makes a tad more sense, and is easy now to understand...

Answer 4

After a while of the earth being a violent place, conditions began to get just a little better. Although the sun's ultraviolet rays were unbelievably destructive, any kind of trace of life could survive... underwater. Slowly, DNA began to form. Not any one kind of DNA, just random, simple DNA sequences which were shielded from the sun and reproduced faster than the harsh conditions destroyed them.

Eventually, over millions of years, they were able to form a "shell" around themselves, and tada! The first cell. Just a simple form of life. Over time they become more complex, developing mitochondria, etc.

It has been proven. Scientitist recreated the conditions of the oceans billions of years ago, and with all the presumed elements present, soon enough they saw VERY SIMPLE DNA forming in the water.

Answer 5

I'm not sure why you think it needed previous genetic information. It has it's own, albeit probably extremely simple. We're not sure how the first organism came into being - but that has nothing to do with evolution. Evolution starts after life has begun.

Well, there was nothing around to eat the original organisms, so they wouldn't have had much trouble surviving.

Answer 6

You assume a cell was always the most basic unit of life? Cells are survival bits for whats in the cell, as well as it being a syntehesized whole. It probably originated from proteins, which eventually became living, and eventually some began mutating to make themselves cells.

Answer 7

there were molecules forming into proteins and after several symbiosis with other protein strings a cell must have developed. There a still organism less advanced than a cell you think of. There are Viruses without even a shell. So why not. I don't think all that would be so long and complicated if it would have been created by a god. A god won't need Proteins, DNA and so on, a god would have been able to make life out of a bag of water.

Answer 8

According to the view of Miller, Urey, and Sagan, they were heterotrophic (other-feeders) and used fermentation (glycolysis + a couple of other steps) to extract energy from the molecules formed as the result of the heat and light in the early atmosphere.

While the earliest autotrophic prokaryotes used hydrogen sulfide gas and produced sulfur (no oxygen, no photosynthesis), later cells used water and produced oxygen gas, the concentration of which rose in the atmosphere.

And yeah, your grammar and spelling offend me.

edit: Amino acids, the basic building units for DNA included genetic variation. Go figure

Answer 9

The first cell would have been that cell which finally contained enough genetic information to survive. The hypothesis is that in the "soup", chemicals were forming, and at one point, DNA was fomed. Perhaps at that time, life was more primitive; perhaps like viri. In any event, the cell itself "evolved" through processes that gave rise to such a being, after which it was able to procreate.

Answer 10

I already told you- the Earth has tons of different kind of conditions. Even if they were all exactly the same, some would have been in the right place for them to thrive. Single celled organisms didn't actually need a lot to live by the way.

Answer 11

I'm not a biologist, but I don't understand why you think it is necessary to have a genetic ancestor to live. If the first cell was genetically successful, then it survived long enough to procreate. It is also possible that the first cell did not survive; that many came before our genetic ancestor and went extinct.
