I know the creationists constantly say that evolution proceeds by chance. But the evolutionists constantly answer that it doesn't. If evolution proceeds according to just the laws of physics, genetics and ecology, then how is that not by chance? Do you and I have different views of what "by chance" mean? What does "not by chance" mean according to evolution?

Chuck, jowpers, and don are all exactly correct.
Evolution has a random element ... variation.
But it also has a non-random element ... natural selection.
What traits appear by mutation is indeed random. But there is nothing random about the fact that if a trait is advantageous, it will tend to propagate into the population, and if it is disadvantageous, it won't last long.
The mistake creationists make when they think evolution is just "random" is that they then look at a complete organism (like a human being) and say things like it's like a tornado blowing through a junkyard and assembling a 747, or a bunch of monkeys randomly banging on typewriters accidentally producing Hamlet. This completely ignores (or misunderstands) how natural selection works. It's NOT just random assembly of atoms, molecules, or spare parts into a final form. Natural selection is a long, long process of tiny incremental improvements ... improvements produced by the NON-RANDOM process of tiny advantages propagating, and tiny disadvantages disappearing. That is all the difference in the world.

Evolution has chance events within it the way the economy has chance events.
For example, two businessmen might meet by chance, and start a company that dominates an industry. But if they hadn't met, SOME company (or perhaps a couple of companies) would dominate that industry. The industry itself would look much the same to the rest of the economy.

Actually, simple chance plays only a minor role in evolutionary change. The major role is played by natural selection, which is almost the opposite of chance. Natural selection is the best-understood mechanism of evolution, and it certainly appears to be the most powerful: because it strongly preserves useful nonrandom change, it seems to be the engine that really drives evolution, and it allows for dramatic, complex changes to occur in relatively short periods of time.

We in no way mentioned it became into the completed answer yet its the perfect ingredient obtainable because of the fact this is overwhelmingly corroborated.. achieveable linkages? No. fossil and DNA info fairly plenty teach linkages previous in simple terms "achieveable". Yeah, there are some gaps, yet fossils are complicated to make. loads of stuff gets destroyed in geological and different organic approaches. If the fossil checklist have been finished we would see plenty extra linkages than we already do. Who mentioned scientists are close minded to different opportunities? Scientists are the main open minded human beings i be responsive to. Scientists are knowledgeable to look on the info. The seen info. The measurable. The trackable. The traceable. technology exist to disprove. no longer teach. The medical technique identity designed to falsify. Evolution were examined extra time which you will shake a stick at. Falsification has no longer befell. Refinement of the suggestions, yet no falsification. Why are you so close minded which you will no longer think of that possibly God/ a god created evolution? He/She/it/they did no longer provide us those brains so shall we blindly stick to some e book packed with dogma.

If you put a gene pool in a cold climate, it would develop a way to deal with the cold. Probably fur or something. Did it develop fur out of chance? Or did the cold climate push the species toward that? So it isn't chance, because there are things that control it.
If the first generation has a variety of animals with different amounts of fur, it is chance to who was born with the fur, but it isn't chance on them surviving.

The word random suggests that which organisms live, die and reproduce is based entirely on chance. Although chance does play a role, traits are actively favoured by natural selection. Traits which result in increased reproductive success increase in frequency with each generation. This process results in a non-random shift in allele frequencies. In terms of macroevolution, this process results in non-random evolutionary trends.

well the thing is evolution is not really a science. people think it is but its not b/c evolution was based on a theory and has be proven yet.
