Natural selection for racism and all pathology

Why is natural selection hard to grasp? It is not what you think…. …human cognitive tendencies interfere more with deep understanding of how natural selection works. Simply put, our intelligence and teleological reasoning interferes with the teaching of pseudoscientific nonsense. The nonsense does not place Darwin’s “conditions of life” before natural selection for reproductive fitness. Natural selection is food energy-dependent and pheromone-controlled in the context of biophysically constrained viral latency. See for comparison: The vibrational theory of olfaction for the…

Biophysically constrained cell type differentiation

Intrinsic limits to gene regulation by global crosstalk Excerpt: A paradigmatic example is that of the aminoacyl transfer RNA synthetase1, which uses kinetic proofreading2 to load appropriate amino acids onto matching tRNAs. This and other examples—including DNA replication, ligand sensing3, protein–protein interactions4,5,6,7,8,9, recognition events in the immune system10,11 and molecular self-assembly12—indicate that biology places a large premium on the reduction of unintended ‘crosstalk’, a generic term that encompasses all potentially disruptive processes due to reactions between non-cognate substrates. Reported as:…

  • What Darwin proved: there’s no such thing as a species
    GENETICS As Animals Mingle, a Baffling Genetic Barrier A short stretch of DNA is challenging what it means to be a species. By: Emily Singer August 5, 2014 Excerpt: “Scientists have dubbed such regions of the genome “islands of speciation.” The persistence of such islands is a phenomenon that has been observed in a variety of […]
