> Don't get too excited. Remember I have the theory tht we will find a system in DNA to push or guide complexification. And you are still stuck with the issue tht all basic change must be in the DNA of germ cells. Liver cells don't toot their own trumpet.-It is now shown that among primates DNA acts differently than in other vertebrate forms. Primates have a great deal more 'alternative splicing' which means genes can make a variety of different proteins, i.e., more complexity. Why should this be? Why is our DNA different than other DNA's when we believe in some form of comment descent? Shouldn't DNA work the same way in everyone? It doesn't:-http://www.sciencedaily.com/releases/2012/12/121220144124.htm-"One of the team's major findings is that the alternative splicing process is more complex in humans and other primates compared to species such as mouse, chicken and frog.
 
"Our observations provide new insight into the genetic basis of complexity of organs such as the human brain," says Benjamin Blencowe, Professor in U of T's Banting and Best Department of Research and the Department of Molecular Genetics, and the study's senior author.
 
"The fact that alternative splicing is very different even between closely related vertebrate species could ultimately help explain how we are unique."-
"The results from the alternative splicing pattern comparison were very different. Instead of clustering by tissue, the patterns clustered mostly by species. "Different tissues from the cow look more like the other cow tissues, in terms of splicing, than they do like the corresponding tissue in mouse or rat or rhesus," Burge says. Because splicing patterns are more specific to each species, it appears that splicing may contribute preferentially to differences between those species, Burge says. "Splicing seems to be more malleable over shorter evolutionary timescales, and may contribute to making species different from one another and helping them adapt in various ways," he says."- Read more at: http://phys.org/news/2012-12-evolution-alternative-splicing-rna-rewires.html#jCp
