Simple question with a 'yes' or 'no' answer. I'm leaving the terms of the poll undefined, so please leave a post with your own definitions of 'evolution' and 'theory', and perhaps a short explanation of your answer.

Danke!

I guess from the perspective of scientific investigation, yes. Theories are never proven.

Yes -- evolution is a theory.

I define evolution as: Δ[sub]alleles[/sub]/T

Theory = an educated guess, based on empirical observation, pending falsification.

U bent van harte welkom!

You mean as opposed to how scientists use the term "theory"?

Theory: A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven. (SOURCE)

I think what you mean, AV, is "Hypothesis".

An hypothesis is an educated guess based on observation. (ibid)

At least that is how it is usually taught to 6th graders and above.

That depends if you honor the marriage of evolution and genetics. Evolution is a theory, genetics is a fact. If you want to join them together then you have talk origin making statements like "evolution is a fact and a theory". Genetics today is considered to be 99.9999% accurate. Or 1 in 100,000 rate of error. Although when you take human error into consideration I doubt if you can consider it to be that accurate.

His definition, as given, encompasses both hypotheses and theories. What is a theory if not an educated guess? What is a theory if it's not grounded in empirical observation? What is a theory if it's not awaiting falsification?

Interesting fact. If a test is accurate 99,999 times out of 100,000, and you want to test for something that occurs in 1 in 10,000 people - i.e., a very accurate test for a very rare thing - how many false positives will there be? That is, if this test is used to jail people, how many innocents will be jailed?

Those jailed equal true positives plus false positives. In a population of X, there are (1/10000 * 99999/100000)X guilty people in jail, and (9999/10000 * 1/100000)X innocent people. The ratio of those figures is (9999/10000 * 1/100000)/(1/10000 * 99999/100000) = 0.1.

In other words, if we use an extremely accurate test to jail people for something that's rare in the overall populace (e.g., "predisposition to child abuse/terrorism/liberalism"), then using those statistics, a full 10% of people jailed by the test would be completely innocent.

Scary.

And tangential .

Maybe but Texas had to release a lot of so called rapists because when they ran the DNA they found out they were innocent. DNA testing cost money so your going to have to have done something to cause them to want to spend the money to test you. They can only afford to put a small number of people in prison. So it should not be to difficult to stay out of that group.

Evolution is a theory.

Evolution: Descent with modification.

Theory: A verified hypothesis.

They can only afford to put a small number of people in prison. So it should not be to difficult to stay out of that group.

America has the largest prison population and the largest incarceration rate in the world, comments like that are scary.

By verified I mean it the hypothesis has been tested and confirmed to be compatible with the rest of science. Usually experiment and peer review verify hypothesis.

The theories which actually get referred to as such like the "Theory of Evolution" and "Theory of Relativity" have a very large base of supporting evidence, however simple hypothesis such as "blue sky is caused by Rayleigh Scattering" are technically also theories once verified.

There's the theory of evolution, and there's the fact of evolution.

Evolution is observable through changes in microbes, plant cultivation and animal breeding; this would be the fact of evolution.

The theory of evolution would be a logical conclusion based on observable facts; for example, combine the fact of evolution, with archeological findings, the nested heirarchy of genetics (and so on so forth with oceans of other facts), and you have the theory of evolution.
