I was just randomly thinking about evolution today, and I thought, what if evolution was just introduced into the scientific community yesterday? Would I accept it? What would it take? Of course, over the years, there has been a great accumulation of evidence for the theory, but how much would you need to be convinced that a single celled organism could change into a H. Sapien?

Why continue? Because we must. Because we have the call. Because it is nobler to fight for rationality without winning than to give up in the face of continued defeats. Because whatever true progress humanity makes is through the rationality of the occasional individual and because any one individual we may win for the cause may do more for humanity than a hundred thousand who hug their superstitions to their breast.

Darwin's ideas were met with pretty stiff resistance when first introduced. It took some time, and a certain accumulation of evidence, for evolution to become accepted.

Ignorance is preferable to error; and he is less remote from the truth who believes nothing, than he who believes what is wrong.

That animals change over time had actually been a widely-spread idea long before Darwin. If I remember correctly, Lamarck wasn't considered a loony by his peers, decades before Origin. What was new with Darwin was primarily the idea that natural selection could drive evolution.

Probably the best story, in terms of a good theory rejected for a long time, is that of Wegener and Continental Drift. There was simply no way to even collect the necessary evidence until some 40 years after the introduction of the theory. But then so much evidence was gathered, so quickly, that the entire geological field was changed in a very short time.

If Evolution or some other revolutionary idea that went against the accepted norm was introduced I would not accept it untill there was 'sufficient' evidence to support it.

It is interesting that it takes a huge amount of evidence to turn an idea into a workable theory or law, but it takes only a small amount of evidence to kill a theory. If evidence was found that dinosaurs and humans lived together at the same time, Evolution as we know it would be 'blown out of the water'.

If I knew then what I know now then I would know more now than I know.

Thats saying a lot... But then again, so far it is the only one that really answers the question...

Contrary evidence does not always kill a theory, it can sometimes just change it. In your example, the fact that dinosaurs and humans lived together does not change the fact that we have observed changes in species due to genetic mutations in the lab, first hand. It would certainly change the lineage of evolution and annihilate setting up this lineage through DNA (as it directly contradicts what the DNA says).

Why continue? Because we must. Because we have the call. Because it is nobler to fight for rationality without winning than to give up in the face of continued defeats. Because whatever true progress humanity makes is through the rationality of the occasional individual and because any one individual we may win for the cause may do more for humanity than a hundred thousand who hug their superstitions to their breast.
