"at least darwin acknowledged the possibility of conclusions opposed to his own[origins"

Creationists deny any other possibility, and declare that they will pray to their own Magical Sky Fairy to help brainwash any doubters to be converted to the Only True Position, without needing to do any further research . They then, as per the convoluted mind games of proponents of 'The Law of Fives' will do any rationalising necessary to keep their beliefs, unlike followers of Science, will will discard things and start research again.

Recent research on aging, for example, has rejected 'oxidative stress' and other ideas as not relevant - in spite of the 'faith' of some of the very researchers that these things really DO work ... :-)

In any lab research on animals, the test animals will do as they damn well please, in spite of what the prejudices of the researchers are.
