Because of one infamous medical case science was shown to be wrong. Therefore science is arbitrarily wrong because AV says so when it suits him, therefore evolution is wrong.
Ah, please don´t get that one wrong. There is a major difference between getting undesirable results and "being wrong".
The whole Thalidomite story is not a glorious one for pharmacy, chemistry or science... but not for any scientific reasons.
AV - and sadly some of his opponents also - act as if "science" should have recognized the teratogentic effects of Thalidomite on humans instantly, and that it was a "failure" of science not to do that.
In hindsight (oh, blessed perfect hindsight!) this might be correct. But it isn´t.
TemperateSeaIsland wrote in posts #5 and #7: "It hasnt been tested as a teratogen on humans." and "I have a better grasp of potential biochemical interactions than my doctor. I just read some papers it hasnt been tested as a tetratogenic."
How would one - how would "science" - evaluate such a claim? It hadn´t been tested as a teratogen on humans, that is correct. Most substances weren´t and aren´t tested as a teratogen on humans. In order to do so.... well, one would have to TEST IT ON HUMANS! Pregnant humans, and observe the results.
How would "science" test the
potential teratogenic effect on humans? A related chemical substance has such an effect and so could Thalidomite. But how to find out... without testing it on humans?
In the case of Thalidomite, animal tests - even for the teratoginic effects - were conducted, with negative results. Only on selected (and not commonly used in tests) species could this effect be shown. How to find out if humans were affected... without testing it on humans?
It can be objected that the "test" that happened was not very scientific, nor even meant as a test. But science is not limited on test-tubes and laboratories. Any incomming data is usable. The data of Thalidomite malformations lead to the results and the "hindsight" knowledge.
It was science that produced the drug and it was science that discovered the effects. From the scientific side, Thalidomite and its story wasn´t a failure. Science didn´t fail here.
Mrs. Oldham Kelsey was mentioned quite early in that thread... but if she is to thank for sparing the USA from the results of Thalidomite, it is not due to a failure of science either.
Mrs. Oldham Kelsey did not know or expect the teratogenic effects either. She did not know beforhand about them - she did not warn about them. She was concerned with other - scientific! - studies that hinted at a direct neural sideeffect of Thalidomite. It was sheer luck that the drug was held back long enough so that the other, more grave effects had been discovered.
And they had been discovered by scientists and analysed by scientists. No independent baptist preacher had warned about Thalidomite.
Science and scientists may reach wrong conclusions from wrong premises, act on non-existent knowledge and take to long to find answers.
But preachers never reach any conclusions, never achive new knowledge and their answeres are always borrowed. At least the answer they borrow from science can be validated... but too often they insist on borrowing from future generations.
