Genome complexity: introns and exons (Introduction)

Exons are used to make protein and introns are an interruptions in the gene itself and must be spliced out. In other words if there were no introns there would not be the need for a complex spiicing mechanism. Therefore it is reasonable to conclude that introns serve some sort of important purpose. A new paper shows that introns do not follow an homologous descent (orthologous is the correct term)every time when gene evolution is studied as evolution progresses.-"The problem is that if the first introns just happened to be randomly inserted into genes for no reason, then there would be no splicing machinery to remove them. And the failure to remove the introns would render the genes useless. This is not to say evolutionists cannot contrive explanations for introns, such as introns initially splicing themselves and the splicing machinery somehow evolving later. But such explanations are circuitous, just-so stories adding tremendous complexity and serendipity to the theory.
 
"Beyond this basic problem, research has also been revealing that introns are not functionless, do not insert randomly in the genome, and do not fall into the common descent pattern. These last two findings were recently reinforced in a new study of a gene known as the eukaryotic translation elongation factor-1a gene."-http://darwins-god.blogspot.com/2013/12/heres-another-study-showing-introns-are.html
