my house came about by chance do you belive me?

Question

no its not likely is it - and its not really complicated in comparrison to a fly - so how did the billions of complex creatures on earth come about by chance?

Answer 1

Evolution is not chance.

Again, you demonstrate an utter lack of understanding of evolution.

I'll say it again (as you like repetition): EVOLUTION IS NOT CHANCE.

Evolution involves chance *at the individual level*, but not *at the population level* which is the level at which evolution occurs.

Chance comes into play with individual mutations. And whether an individual is tall or short, or fast or slow is a matter of chance. And whether an individual gets snagged by a crocodile by wandering too close to a river may be a matter of chance.

But the fact that tall individuals *on average* tend to have tall children is NOT chance. Or that fast individuals *on average* tend to have fast children, that tendency is NOT chance. But even more important, if fast individuals avoid crocodiles better, then *on average* they will produce more offspring. That is NOT chance.

And that is how the billions of complex creatures on earth came about. NOT BY CHANCE.

Oh, and for your house analogy ... 5 words: HOUSES DON'T REPRODUCE WITH INHERITANCE.

Answer 2

Chance plays a part in evolution (for example, in the random mutations that can give rise to new traits), but evolution does not depend on chance to create organisms, proteins or other entities. Quite the opposite : natural selection, the principal known mechanism of evolution, harnesses nonrandom change by preserving "desirable" (adaptive) features and eliminating "undesirable" (nonadaptive) ones. As long as the forces of selection stay constant, natural selection can push evolution in one direction and produce sophisticated structures in surprisingly short times.

As an analogy, consider the 13-letter sequence "TOBEORNOTTOBE." Those hypothetical million monkeys, each pecking out one phrase a second, could take as long as 78,800 years to find it among the 2613 sequences of that length. But in the 1980s Richard Hardison of Glendale College wrote a computer program that generated phrases randomly while preserving the positions of individual letters that happened to be correctly placed (in effect, selecting for phrases more like Hamlet's). On average, the program re-created the phrase in just 336 iterations, less than 90 seconds. Even more amazing, it could reconstruct Shakespeare's entire play in just four and a half days.

Answer 3

In nature we have many examples of complexity evolving from simpler elements.

Here is a primer on abiogenesis for You:
In brief, organic chemicals formed from simple chemical reactions. Eventually nucleic acids were formed by the bonding of organic chemicals. That can be even be reproduced in a laboratory. Chains of nucleic acids formed RNA. Eventually an RNA molecule capable of self replication (simply by having a certain sequence of nucleobases) would have been formed. This would have led to an RNA phenotypic world. Simple molecular shards of RNA, once capable of self replication, would have been subjected to an evolutionary process. But a chemical evolutionary process different from biological evolution. For instance, distinct phenotypes of RNA could have joined or bonded together to form new phenotypes. Later, advanced forms of phenotypic RNA, with the ability to synthesize proteins, store genetic information and reproduce would have evolved. Eventually we would have had viral-like shells synthesized by RNA strands, consisting of maybe as few as 150 codons. We are still a long way away from a cell with complex chromosomes built of DNA, but we are getting there, step-by-step, no?

That life came about first by chemical evolution and later through biological evolution is no longer a matter of scientific contention. The really hot question now in science is whether phenotypic RNA evolved protein synthesis and metabolism, or whether these chemical processes started independently (it appears that this is chemically possible) and then merged in an endosymbiotic process.

Answer 4

Eh - chance ? Who says they came about by chance ?

Pick up some books, go to school and you'll learn all creatures and plants share something - we are created of the complex combination of chemicals and electrical reaction. Mix them and complex creatures appear over millenia.

Much the same as your house - someone mixed some mortar, laid some bricks, put a roof on ...

Answer 5

Your connection to the Yahoo server via the Internet was done using algorithms that have chance at their heart to come up with the "best least cost solution".

And even though this clearly worked and you posted your little rant, you seem stuck on the idea that chance cannot lead to structure.

You need to learn more about how stochastic processes work.

Answer 6

it wasn't by chance, it was from millions of years of evolution

aren't you tired of ranting for one day?

Why don't you waste your energy on really helping people out instead- this is very selfish and unchristian of you

Answer 7

How many millions of years did it take?

Answer 8
