A Creationist Myth About Science And Evolution May 31, 2010

Creationists often point to the fact that science can change.  Using evolutionary science as an example they are always bringing up items such as finding what was thought to be an extinct species still living or finding that land plants existed in the Cambrian period when it had been thought none did or finding that evolution may have occurred in starts and stops instead of a smooth progression as evidence against evolution.   

 Somehow they feel that changes such as these and others show that science cannot be trusted.  That science keeps having to correct itself.   They are blind to the reason why this occurs and why, far from being a sign of weakness, it is one of science’s towering strengths. 

 The reason for this is human knowledge is always incomplete.  We do not know everything and to pretend that we do is both arrogant and foolish.  

 Lets use a logic word puzzle for an example. 

 Suppose that you know that there were four horses in a race and each was wearing a different color.  The question is what horse was wearing which color and in what order did they finish. 

 Given only the information above you couldn’t even begin to guess.  However say that you did some research and found out that the four horses were named Dare Devil, Bitter Twist, After Dinner, and Catch Me. 

 You also found out in your research that the colors they were wearing were blue, red, green, and yellow. 

 We know more but not enough to answer the question with certainty.  We know the names of the horses and the colors that were worn.  We can now speculate on where each horse placed and what color they wore.  And then do the research to see if we were correct.

 Lets say that initially we thought that Catch Me was first and was wearing red.  Next was Bitter Twist wearing yellow, followed by Dare Devil wearing green and After Dinner wearing blue.  

 Now we do a bit more research, looking into newspaper articles, talking to people who were betting on the track that day, talking to jockeys, etc.  And we find out that Catch Me was last. 

 We were wrong on where Catch Me placed.  However does this negate that Catch Me was in the race? 

 No.

 Does this negate that the other three horses were in the race?

 No. 

 Does this negate that each was wearing one of the colors listed?

 No. 

 The basics are still true and are not affected by being wrong on the order.  In fact we are now closer to knowing for sure who place in which spot and what color they wore. 

 In fact our research did verify that Catch Me was indeed wearing red.  So that part was also correct.  We have increased out basic knowledge.  Our total knowledge of the race has increased, although we still do not know with certainty who won the first three spots nor what colors they wore. 

 Next we find a picture of the race taken on the home stretch.  It shows Bitter Twist and After Dinner going nose to nose with Bitter Twist having a very slight lead.  Right on their heels is Dare Devil. 

 Unfortunately the picture is a black and white one so we cannot really discern the colors they wore.  However we make our best guess based on how light and dark the colors were. 

 Based on this evidence we now believe that Bitter Twist won the race and was wearing Green.  Next was After Dinner who was wearing blue.  Third place was Dare Devil wearing yellow.  And of course we already know for sure that Catch Me wearing red came in last. 

 Now while we have some evidence for all of the above the evidence for the first three places is not as certain as that for last place.  And sure enough, after doing even more in depth research we find out that parts of our answer above is wrong. 

 We find out that Bitter Twist stumbled and as a result fell to third place.  We also find out that he was actually wearing blue instead of green. 

 We find out that Dare Devil surged at the very last minute and won the race.  We were correct though in that he wore yellow. 

 Finally we find out that After Dinner, wearing green, actually came in third. 

 Notice how finding out the truth about some of the more speculative parts (because of  current insufficiency of evidence) did not in any way negate those parts that had solid evidence. 

The fact that we were wrong initially on who won the race did not in any way negate the fact that a race occurred, that four horses were in it and that they were wearing different colors.

The fact that we were wrong on the first three places did not in any way negate the above nor did it negate the fact that we were correct on which horse came in last.  And we were correct on some of the colors worn by the horses.

 Science is just like this.  It has a bedrock of well established and amply evidenced theory and facts.  The fact that sometimes it is wrong on some of the speculations based on this bedrock does not negate the bedrock.  

The evidence for evolution occurring is still just as strong as it was before even though scientists believed at one time that there were no land plants during the Cambrian.  Just as being wrong on the order of who won the races did not negate the fact that a race had occurred run by four horses so too land plants in the Cambrian not negate the fact that evolution has and is occurring.

 Further this methodology does not pretend it knows everything and desperately ignore new evidence.  It accommodates it and uses it to increase the bedrock knowledge that science does posses. 

 That is why science keeps gaining in knowledge while those who are so arrogant and foolish as to believe that a book gives them all knowledge lose ground.
