Let there be anti-entropic light (2)

Physics

Without knowing anything about the biophysically constrained chemistry of protein folding that links light-induced amino acid substitutions to the stability of DNA is the organized genomes from plants via bioluminescent bacteria in squid, the pattern of nutrient-dependent biologically-based cause and…

The biologically-based origin of the mammalian placenta

The past is not the key to the present

Summary: In this open access journal article, Gunter Wagner’s group eliminates assumptions about mutations and ends the obfuscation of biologically-based cause and effect. Experimental evidence links ecological variation via non-living viruses to ecological adaptations manifested in the biodiversity of morphological…

Constrained evolution is ecological adaptation

translocated chromosome

See also: Unconstrained evolutionary innovability Ideas that evolution is not constrained can be compared to experimental evidence of biophysically constrained ecological adaptations. The most recent relevant open access published work from the Jakobsson lab is: TRIM28 Represses Transcription of Endogenous…
