Re: Evolution or De-evolution?

... to autism, I think it’s time to rethink this conclusion. (http://www.ncbi.nlm.nih.gov/pubmed/16151044). My second problem is the idea of genome duplication. At first the genome duplication was said to be the driving force of evolution by providing the genetic material for mutations leading to ...

Your are just wrong. There is tons of evidence. See Taylor, J.S. and J. Raes. 2004. Duplication and divergence: the evolution of new genes and old ideas. Ann. Rev. Genet. 38:615-643. This paper is nearly ten years old and only took me a minute to find! Just because ...

Re: Re:

You are right and wrong at the same time. Translocation and duplication take place - fact. This can result in a new trait - fact. However, we talking about the SAME (already present in the gene pool) DNA material. "This extraneous DNA, if further ...
