As has been pointed out Kerner fails to take into account the fact that local decreases in entropy are not disallowed by thermodynamics. Moreover he fails to take into account that it is reproduction rather than evolution as such which deals with the actual entropy decreases.
The existence of "junk DNA" is a small puzzle in evolutionary terms but it is certainly not a contradiction. The idea that 95% of the human brain is dormant is not even true.
Moreover he fails to understand that evolution is not "progressive" - that is why some lineages will show what we think of as "progress" others will not - and even show what he would call "devolution" - although it is still evolution.
His idea that ALL evolution is what he calls "devolution" is clearly contradicted by the fossil record. For instance maller-brained species in the genus Homo precede modern humans and more ape-like species precede them.
As to Bieberich's work, from my own reading it seems likely that it refers to developmental changes and as such the only information "lost" would be that that was "restored" by the mutations created by Bieberich. Without more details it is impossible to tell whether Kerner's interpretation is correct - but I strongly suspect that it is not. Certainly Bieberich has used mice to investigate the effects of Hox genes (e.g
