Genetic Complexity and the Origin of Life

I found a recent study done by MIT really interesting. (Read overview here.)

This study done by geneticists found that, based on the fossil record, information in the genome increases exponentially--just like Moore's Law predicts for other forms of information capacity.

Moore's Law was developed to predict integrated circuit capacity, and found that it doubles roughly every two years. Looking at recent data and using this rule of thumb in reverse, you can predict the date at which the first integrated circuit was born--and you come up with the 1960s, which is exactly right. Using the same concept, you can look at the number of scientific publications, which double every 15 years or so...working backward, this puts the start of scientific publication at about 1710, the era of Isaac Newton and dawn of modern science.

The point is that systems which use information seem to follow an exponential curve. Interestingly, geneticists found that DNA follows that exact same pattern between different types of creatures: it seems that the complexity of genetic code doubles roughly every 375 million years or so. Even more interestingly, when plotted on a log scale you see that this concept perfectly predicts the complexity of the genome with almost no error (see graph below).



What's the point? Well, geneticists were very surprised when they ran this calculation, because it turns out...life could not possibly have evolved randomly to this point given the age of the Earth. In order for the genomic complexity we find today, the Earth needs to be between 7.2 and 12.2 billion years old! In other words, the 4.5 billion year old Earth is about half the age it needs to be for evolution to be true!

This goes along, of course, with something I have often said:  evolutionists hate the Big Bang model (once they really understand it). Darwinian evolution arose in an era where most scientists believed the Earth was infinitely old ("Steady-State model"), and opposed most cosmologies which put a creation date in. In fact, the phrase "Big Bang" was developed by evolutionary steady-staters in an attempt to discredit the theory (which they found uncomfortably close to Genesis 1's account of creation).

So here we have our genetic evidence telling us that there is no way random evolution could happen given the age of the Earth--it isn't even close. How is this not headline news to every Christian? It is a fantastic evidence of our faith!

(Of course, the authors of the study do not convert to Christianity as a result of the study...rather, they suppose that life must have started on some asteroid and stayed frozen in ice until luckily landing on the Earth. Somehow that explanation manages to make evolution even less plausible than it already is!)

No, this is clear evidence of what I have long said: the genome is far too complex, and carries far too much information, for life to have happened or evolved randomly. Have animal bodies changed/evolved throughout history? The fossil record says yes, definitely. The question is not whether creatures adapt to their environment, but whether this happens randomly (evolutionism) or purposefully (creationism)?

And here we have yet another great piece of evidence that shows how ridiculous the theory of randomness really is--don't let it pass unsaid!
