how did one celled creatures manage to become such a massive variety of life?

Question

i mean, i can use my imagination to see how a one celled creature could "evolve" into another form, some creatures, such as butterflies do it today. but i think it is stretching it some to believe that they could decide to become this or that, which is what they would have to do, otherwise all life on earth would be the same.

kurious_kitten...thats an oxy-moron...to believe in both God/Jesus and evolution...you either believe in God or you don't...and if you did you would know that evolution ISN'T

Answer 1

Thats right it's far fetched, because it's hog wash, the evolutionist would have us believe, that every living creature came from rock, give me a break, It's kind of funny how they'll say anything, no matter how stupid it is, just to not admit theirs a God that created us all, they want to think that it took millions of years for the Colorado river to cut out the Grand Canyon , when in fact it was actually fast after the flood of Noah's days, great walls of water carved in out within a matter of days, not millions of years, these people can't imagine it so they wont believe it. but if they want to believe this hog wash fine, but they dare to force this load of horse crap, on our children . and that burns me up I have no problem so much with adults believing what they want but keep your influence off my kids... thats how I feel about that subject anyways, Evolution is a crock it's time we tell them not to spread their lies, any more they can't back their claims up, an their to scared to debate, with an creationist because they know they'll loose !!!

Answer 2

There is no "decision". Life does not replicate itself perfectly. Most variants (mutations) are inferior and eliminated by natural selection. That which does not work well, does not reproduce itself.

Cells that grouped together gained an advantage, in nothing else, by sheer mass. Then each cell taking on specific functions creates a new advantage. The process is involved, and evolution refers to the process of gradual change. The processes that led to sea sponges were involved enough.

From specialized cells, you then get tissue layers, then specialized structures. Segmented structures allowed specialization over the length with specific organs at specific locations.

I don't want to go too far , since I have just condensed several biology courses down to three paragraphs.

Answer 3

This is an evolutionist theory. By slow, or sudden mutations, life has changed. Some changes causes death, others survive. Does that mean it's true? Depends on your beliefs.
Biblically, the book of Genesis mentions God creating life in a specific order....similar to the order of evolution. Scientists have also discovered deep soil samples that support a time when there was a sudden explosion of life within a short time frame. Creationism? You be the judge.

Answer 4

There is an enormous amount of information about evolution in books and on the internet. There is more evidence for evolution than there is for either Newtonian or Einsteinian gravity. If you would like to learn something of it, a good place to start would be the Talk Origins Archive at http://www.talkorigins.org
Start with the FAQ.

Answer 5

have not been insulted on 360 yet the following I actually were many situations. Worst - there grow to be guy suggested as "taking a piss" a sad guy with a pretend identity going round calling all Arsenal followers truly me a 'wh---' and an 'ape'. Hes a United fan, i understand him, hes more often than not round in the united kingdom area yet from time to time comes on to the following. I wont say whom, it is going to create dissimilar difficulty. He must have an fairly fairly unhappy existence to go back up with a pretend identity to insult someone for no reason.

Answer 6

There are several elements.

First, there are mutations (changes) from one generation to the other, some of those changes generate an advantage for some individuals, who tend to prevail.

Second, the time scale of the process is very hard to imagine: we're speaking of millions of years.

Third, there is not an unique solution to the problem of surviving. Some animals survive by flying, or by swimming, or by being small, or by being large, etc. There are ecological niches (places/times/behaviors) for many different types of beings.

Answer 7

It's a pretty complex process, and took millions of years. It's not like a single cell suddenly decided to be a rabbit, and poof, it became one. (That would be similar to the religious explanation...) Single cells evolved into simple multi-celled organisms over time. Those evolved into more complex organisms, over time. This continued, and as life spread over more diverse environments, with more diverse survival demands, as would be expected, it diversified.

Answer 8

Its not like it was one, one-celled organism. Diversity was always there. When many things change in many different ways effected by many different environments will lead to many different looking creatures. Add to that mass extinctions and we get a lot of species with a lot of similarities.

Answer 9

You have less-than-an-elementary understanding of evolution. Creatures don't "decide" to evolve. They do it as the environmental and genetic conditions permit. Also, organisms don't change from one type to another within a few generations; the process is very slow. After this, I am too lazy to go through my library of knowledge within my mind to enlighten your simple-minded talk.

Answer 10

It wasn't a matter of decision, but a matter of natural adaptation. Our veins don't pump blood against the pull of gravity because we will it to, they do it because they have to.

Organisms naturally adapt to the habitat they're exposed to. And one-celled organisms had an advantage, as they can easily multiply and they can perform all functions on their own, without reliance on any other cells (with the exception of yeast and other unicellular organisms that work in colonies).
