The biologically-based origin of the mammalian placenta (2)

See also: The biologically-based origin of the mammalian placenta I’ll preface this follow-up on the origins of the mammalian placenta with comments that attest to foolishness of theoretical physicists who try to link Big Bang cosmology to neo-Darwinian theories about mutations and evolution. RPF Interviews Dr. Alexander Unzicker Excerpt 1)  “It annoys me too much The biologically-based origin of the mammalian placenta (2)

Environment epigenetically shapes the immune system

Environment, more than genetics, shapes immune system 1) –with my emphasis Re: “There’s nothing here that is revolutionary or requires rethinking of our assumptions about how the immune system functions…” My comment: They removed assumptions about cell type differentiation by linking differences in metabolic networks to genetic networks. They indirectly showed that ecological adaptations are Environment epigenetically shapes the immune system

Constrained evolution is ecological adaptation

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 Retroviruses in Neural Progenitor Cells. This is a link to a prior publication (also open Constrained evolution is ecological adaptation

Unconstrained evolutionary innovability

The Strange Inevitability of Evolution by Philip Ball Excerpt 1)  Natural selection supplies an incredibly powerful way of pruning variation into effective solutions to the challenges of the environment. But it can’t explain where all that variation came from. As the biologist Hugo de Vries wrote in 1905, “natural selection may explain the survival of Unconstrained evolutionary innovability

From Hydra to humans vs a Lakatosian research program

Imre Lakatos Excerpt: “A Lakatosian research programme[8] is based on a hard core of theoretical assumptions that cannot be abandoned or altered without abandoning the programme altogether. More modest and specific theories that are formulated in order to explain evidence that threatens the ‘hard core’ are termed auxiliary hypotheses. Auxiliary hypotheses are considered expendable by From Hydra to humans vs a Lakatosian research program

Communication, not mutations

Communicating Across Kingdoms? Researchers pinpoint microRNAs that could play a role in how Wolbachia bacteria manipulate their arthropod hosts. By Sandhya Sekar | December 15, 2014 Excerpt: “I am not sure that I would call this ‘communication,’ however,” he added, as the authors have in their paper. My comment: I’m rather certain that no evolutionary Communication, not mutations

Models by evolutionary biologists are not models

How Networks Are Revolutionizing Scientific (and Maybe Human) Thought By John Edward Terrell, Termeh Shafie and Mark Golitko | December 12, 2014 | Excerpt: “…evolutionary biologists are now modeling series of complex networked relationships at multiple levels ranging from individual “letters” in the genome to protein-gene networks to interaction networks between organisms, thereby demonstrating that our Models by evolutionary biologists are not models

The future of physics predicts no future for evolutionary theory

The ever-smaller future of physics ‘Theory of everything’ captures Weinberg’s imagination in Lee Historical Lecture Excerpt: “…there are hints that the answers to fundamental questions will reveal themselves at around a million billionths — between 10­-17 and 10-19 — of the radius of the typical atomic nucleus. My comment: Evolutionary theorists may not recognize the The future of physics predicts no future for evolutionary theory
