Another example of Cherry-Picking

It has been long been theorized that North America was originally populated by people coming over a land-bridge across what is now the Bering Sea.  Evidence of such migration has been presented often and little disputes it.  There are disputes over the exact dates, number, and duration of such migrations, in other words some of the details, but the basic theory is well supported.

Well, I caught a new headline from The Christian Times from my Google Alerts.  I know, I know, it's not exactly an authoritative source for much of anything, but it does support something I have said often -- creation pseudo-scientists are perfectly willing to accept some science, providing they can cherry-pick only certain parts of it and discard anything that disagrees with their religious beliefs.  Here's the story: "Discovery of ancient DNA in Alaska supports Tower of Babel account, creationists say".

"A team of researchers . . . sequenced the infant's DNA and compared it to that of modern Native Americans as well as to other ancient and living people across Eurasia and the Americas . . . The team believes that the infant's group and modern Native Americans shared common ancestry with people who crossed from Asia to North America through a land bridge called Beringia some 25,000 years ago."
OK, a study in Nature provides more evidence supporting the Bering Land Bridge.  That's fine in and of itself.  But then a creation pseudo-scientist who works for little kennie ham at Answers in Genesis (AiG) claims that this does support the Genesis story of the Tower of Babel's migration -- however the dating is flawed because it couldn't possible have happened some 25,000 years ago, kennie and his Hamians at AiG doesn't believe the Earth is that old.

So . . . according to kennie and co. when God messed with the people building the Tower and changed all their languages so they could not communicate and continue building a tower that would reach God's front door, they traveled from the Middle East, through all of Asia, crossed the Bering Land Bridge and settled North America all at once.  At the same time they migrated across Europe, Africa, Australia, and all the other islands of the world.  Hmmm, no stretching credibility there.

Of course, there isn't any real support for the Tower of Babel story, it's an origin myth to explain why there are so many human cultures and languages.  But notice how the AiG guy takes part of an actual scientific discovery and spins it to support his religious beliefs -- and yet dismisses other parts of the discovery because of those same religious beliefs:
"Nathaniel Jeanson, a Harvard-trained research biologist with Answers in Genesis (AiG), believes that the dating of the infant girl's DNA was not accurate. However, he said that the other details of the discovery support the Genesis 11 account of mass human migration after the attempt to build the Tower of Babel."
Does anyone really wonder why no one takes creation pseudo-scientists seriously?  AiG's Jeanson is joined by another pseudo-scientist:
"Kurt Wise, a Southern Baptist and Harvard-trained paleontologist, suggested that the 11,500 "radiocarbon years" cited in the study "amount to many fewer true (chronological) years (probably closer to 4,000-4,100 years).""
Were either of these two researchers on the team that made this discovery?  No!  They are simply taking other peoples work, cherry picking some of it, tossing aside the rest and declaring some sort of religious victory.  Have either of them provided evidence that the dating techniques are wrong?  No, they simply wave the Bible and use something called 'biblical chronology', which is somewhat interesting because there is no clear understanding of such a chronology, since it seems to change from sect to sect.  But details like that matter little to the dedicated pseudo-scientist!

Just to be clear, I am not using The Christian Times as an authoritative source, just as an example of how real science is cherry-picked by armchair pseudo-scientists.  I love how they work in that these two are Harvard-trained, like the education they may have been exposed to at Harvard means anything at all to them.  I would be very surprised if they were honest with their beliefs system or their planned use of their education while they were at Harvard.  In my opinion, these are two more examples in the 'Liars for Jesus' club.  Like so many others who misrepresented themselves for the purpose of having an assumed credibility based on their education.  

  I've written about Jeanson before "It's Late, but Answers in Genesis might be joining the 20th century . . . finally!"  I don't recall Wise, but I am sure his name will come up again.  He's a consultant at AiG as well as working at a private Christian college.  Well if that doesn't work out for them in their current positions, maybe the Institute for Creation Research (ICR), Access Research Network (ARN), or Liberty University is looking for help.

So what exactly is 'Junk' DNA?

Here is something I mentioned in the last post, "DI's knee-jerk anti-ID whine" and it's one of those terminology word games the less-than-honest fellows at the Discovery Institute like to use. They seem to think that scientists decades ago wrote off 'Junk DNA' as junk. It sounds good, because like their mistreatment of the words 'theory', 'belief', and 'academic freedom', all they tend to do is try and confuse folks. Now why in the world would the DI not care if people understood the truth? Because having folks know the truth is not something that will help the DI's marketing and fund raising schemes.

So what is 'Junk DNA'? Back about 40 years ago a real scientist, geneticist and evolutionary biologist Susumu Ohno, coined the term to identify portions of a genome sequence for which no discernible function had been identified. Please note it wasn't to claim that a function would never be identified, nor was it that there was no function, but that at the time "no discernible function had been identified."

Today 'Junk DNA' is considered an obsolete term because many advances over the last 40 years has identified functions for what used to fall under that label. Who still uses the term? Popular press certainly does, and so does the various Creationists who are looking to discredit real science -- and doing a pretty lousy job! I mean using a 40-year old out-of-date term is a pretty poor job of discrediting something, right?

So now let's look briefly at more of the facts, something the DI tends not to do. If actual biologists had considered large portions of a genome to be junk -- as in worthless -- who was it that made these advances in identifying functions for previously unidentified parts of a genome? Was it those hard-working Intelligent Design scientists? Anyone ever seen a hard-working ID 'Scientist'? The very few ID proponents who are actual scientists are too busy marketing to be doing any actual work.

So what is the ID proponent supposed to do? Well if you are a typical ID proponent, like those 'fellows' at the DI, you sit back on your well-funded ass and claim that each discovery by real scientists could 'hypothetically' be used as a prediction to support Intelligent Design. Of course putting the word 'hypothetically' in front of their prediction means they don't actually have to make a prediction and they can't be blamed if it doesn't come true.

In the mean time scientists -- using evolutionary theory, science, and scientific methodologies -- keep expanding our knowledge of the genome and finding many purposes for what was not identified 40 years ago. I think this identifies a cornerstone of trouble for the DI. I mean while they are busy marketing and failing to provide support for their pet ideas, science keeps pushing the boundaries of our knowledge forward and they get further and further behind the proverbial eight-ball.

Such a nice thought -- casey and friends running away from a giant eight-ball as they head toward the only shelter, labeled 'Science'. The sad thing is that unlike the DI, there won't be a lock on the door. All are welcome, providing you shed your religious-based preconceptions and are willing to work using an actual methodology. Personally I think the 8-ball would get them!
