Alternative splicing of exons changes the meaning of simply expecting one gene, one protein. By splicing exons together and removing the introns taht are inbetween, the genome can make anyting, even different species. Did evolution make this mechanism as life developed or was the splicosome there from the beginning, and is the source of complexification? I have predicted we would find such a mechanism? It is an easy jump for me to say God created the genome to act this way-Two more articles which show that our DNA may look like 98% of chimp DNA, but alternative splicing gives a whole new set of species instructions, or organ instructions:- "Blencowe's team showed that the species-specific alternative splicing changes tended to be driven by differences in the transcripts themselves, which carry a splicing code that guides the splicing machinery—rather than differences in the splicing machinery. For example, human transcripts expressed in mouse cells exhibited human, not mouse, splicing patterns, despite being spliced by mouse machinery." The bolded is a key finding.-
http://www.the-scientist.com/?articles.view/articleNo/33782/title/Evolution-by-Splicing/-Again, the observation that this mechanism was present from the beginning of life counters the theory that this degree of complexity evolved-"Scientists have wondered why vertebrate species, which look and behave very differently from one another, nevertheless share very similar repertoires of genes. For example, despite obvious physical differences, humans and chimpanzees share a nearly identical set of genes.
 
The team sequenced and compared the composition of hundreds of thousands of genetic messages in equivalent organs, such as brain, heart and liver, from 10 different vertebrate species, ranging from human to frog. They found that alternative splicing -- a process by which a single gene can give rise to multiple proteins -- has dramatically changed the structure and complexity of genetic messages during vertebrate evolution. 
The results suggest that differences in the ways genetic messages are spliced have played a major role in the evolution of fundamental characteristics of species." Again the bolded is key!-http://www.sciencedaily.com/releases/2012/12/121220144124.htm-Repeated for emphasis: Again the observation that this extremely complex mechanism was present from the beginning of life counters the theory by evolutionists that this degree of complexity in the genome evolved. It is like an airplane deciding how to build itself. No way!
