Excerpted from Kohl (2013)
“In flies, ecological and social niche construction can be linked to molecular-level cause and effect at the cellular and organismal levels via nutrient-dependent changes in mitochondrial tRNA and a nuclear-encoded tRNA synthetase. The enzyme enables attachment of an appropriate amino acid, which facilitates the reaction required for efficient and accurate protein synthesis (Meiklejohn et al., 2013).”
My comment: The mitochondrial interactions that enable efficient and accurate protein synthesis are central to my model. The moderator of the ISHE’s human ethology yahoo group finally realized that understanding the role of mitochondrial interactions is essential to distinguishing the differences between what is currently known about cell type differentiation and theories that ignore the mitochondrial interactions. The theories seem to claim that protein synthesis occurs via mutations that are naturally selected and result in the evolution of biodiversity. However, it’s not possible to get a theorist to say that. Even an uninformed theorist knows how ridiculous it is to claim that protein synthesis, which is nutrient-dependent, occurs in any other context outside the context of ecological variations in the supply of nutrients.
Feierman again uses a barrage of posts, a tactic common to the news media, to keep the focus on evolutionary theory — if only because accurate representations of cause and effect are extremely difficult to understand. If you feed people too much information, they will soon make no effort to understand any of it. Instead, they will continue to believe what they’ve been taught to believe, no matter how clear it becomes to others that they have been taught to believe in pseudoscientific nonsense.
Feierman posted these four links to two different articles along with about 25 other posts today:
Shaping the dynamic mitochondrial network

BMC Biology 2014, 12:35 (27 May 2014)
Mitochondrial network dynamics
Mitochondria in eukaryotic cells form a constantly fusing and breaking network whose dynamics reflect and affect the physiological and metabolic state of the cell. In her contribution to our article series on mitochondria, Laura Lackner reviews what we know of the regulation and mechanisms of mitochondrial network dynamics.
Mitochondria as signaling organelles

Many modes of signalling by mitochondria
In his contribution to our series on the biology of mitochondria, Navdeep Chandel tracks the emergence of mitochondria as signalling organelles, and the new directions in which research on mitochondrial signalling is leading.
The challenge is to try to make any sense at all of Feierman’s posts. It may also be challenging to attempt to understand how nutrient-dependent changes in mitochondrial tRNA and a nuclear-encoded tRNA synthetase. enable appropriate amino acid substitutions that facilitate efficient and accurate protein synthesis. However, there’s a model for that. It can be compared to Feierman’s opinion:
“I am absolutely certain that if you showed this statement to any professor of biology or genetics in any accredited university anywhere in the world that 100% of them would say that “Random mutations are the substrate upon which directional natural selection acts” is a correct and true statement.”
