The vibrational theory of olfaction for the win
…he and his co-authors delve into more of the specifics of olfactory receptors, including particular amino acid motifs, metal binding capacities, and disulphide bridge redox status. It turns out that amino acid side chains alone frequently pull off some rather interesting electron transfer effects without the need for fancy co-enzymes or prosthetic groups.
See for an example of what one enzyme can do:

High magnification of the slime mold Physarum polycephalum shows the cytoplasm pumping furiously through its huge single cell.

This cytoplasmic streaming allows the slime mold to push forward toward nutrients and potentially carpet a surface.
For the logical extension of what is known to all serious scientists about how to link the sun’s anti-entropic virucidal energy to the creation of different enzymes and from quantum physics to quantum souls, see:
“…to believe that you are, right now, thinking with anything other than a hive of independently living neurons is naive in the extreme…” — Robert Karl Stonjek
To believe that Robert Karl Stonjek does not understand the fact that every aspect of neo-Darwinian evolution has been refuted in its entirety by this model, makes you an example of human idiocy.
Nutrient-dependent/pheromone-controlled adaptive evolution: a model
The honeybee model organism exemplifies what has been learned from the study of invertebrates (De Loof, Lindemans, Liu, De Groef, & Schoofs, 2012). This includes what has been learned about the epigenetic effects of nutrients and pheromones on juvenile hormone (JH). However, the molecular biology of cause and effect that is common to all species was left behind, and the epigenetic effects of human pheromones have not typically been considered in the same context as epigenetic effects of food odors and insect pheromones or the epigenetic effects of pheromones on other mammals.
To believe that Jay R. Feierman is not an example of human idiocy makes you an example of human idiocy.

I agree. That’s why this claim stands out as an example of pseudoscience.
Amino acid composition of proteins varies substantially between taxa and, thus, can evolve. –Jordan et al., (2005) A universal trend of amino acid gain and loss in protein evolution
The pervasive nature of pseudoscientific nonsense probably led to this claim:

Jay R. Feierman: Variation is not nutrient availability and the something that is doing the selecting is not the individual organism. A feature of an educated person is to realize what they do not know. Sadly, you don’t know that you have an incorrect understanding [of] Darwinian biological evolution.
