Further explanation of epigenetic controls by incRNA and othr heritable methods that look very Lamarkian;-http://the-scientist.com/2012/10/01/lamarck-and-the-missing-lnc/-Darwin's concepts are being squeezed by all these new findings. Don't blame Darwin; he never conceived of this complexity. But his followers can't give up on the idea that evolution is entirely non-directed.

One major form of epigenetic controls is methylation of areas of DNA,which modifies the expression of the DNA code. It is now found that a certain protein maintains the methlyation and it not just DNA reduplication that causes the retention of the methyl groups. Again, the genetic controls are shown to be more and more complex. -http://phys.org/news/2012-09-scientists-link-players-epigenetic-code.html-Also see how incRNA can play a role resulting in heritable changes:-http://the-scientist.com/2012/10/01/the-epigenetic-lnc/

Epigenetics: hopping enzymes (reply)

Enzymes are giant protein molecules, but they can hop from one side of DNA to the other to make important modifications. Do they have a mind of their own? - http://phys.org/news/2012-07-enzyme-epigenetic-gene.html

lac is just a simple little molecule exploring DNA by 'walkng along' the groove and then grabbing on. They make it sound like strolling down the street. How does the molecule 'know' what it is doing? The process has purpose! They said so. It is looking for the right spot. That is teleology, which isn't allowed in Darwinian research. All developed by chance. Tell me how.-http://sandwalk.blogspot.com/2012/07/slip-slidin-along-how-dna-binding.html#more
