“Evolution” of two sexes?

social interaction and brain

Selection for mitochondrial quality drives the evolution of two sexes with germline Topics included (among others): CORRELATION BETWEEN ANIMAL DEVELOPMENT AND MITOCHONDRIAL EVOLUTION THE MODEL: SIMULATION, MATHS TOO COMPLICATED TO SOLVE Mt VARIATION BETWEEN GAMETES MAKES SOMATIC GAMETOGENESIS ADVANTAGEOUS IN…

Atoms to ecosystems is not almost a molecular ecology

terrarium eco system

In Kohl (2012) I wrote: Among different bacterial species existing in similar environments, DNA uptake (Palchevskiy & Finkel, 2009) appears to have epigenetically ‘fed’ interspecies methylation and speciation via conjugation (Fall et al., 2007; Finkel & Kolter, 2001; Friso &…

From Hydra to humans vs a Lakatosian research program

translocated chromosome

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…

Thermodynamic constraints and ecological adaptations sans evolution

Physics

Relationship between protein thermodynamic constraints and variation of evolutionary rates among sites Excerpt: “…a two-variable model that combines stability and stress signi ficantly improves predictions. Therefore, both the overall stability [symbol] and the stress [symbol] seem to capture distinct thermodynamic constraints on…

The key to science: experimental evidence

  If it disagrees with the experiment, it’s wrong! — Richard Feynman (1964) Two different experiments are among others from the Vosshall lab that show the theory of evolution is wrong. 1) This experiment links induced mutations in olfactory receptor…

Pharmacogenomics

genetic code RNA medium

“The gene, cell, tissue, organ, organ-system pathway is a neuroscientifically established link between sensory input and behavior. Marts and Resnick (2007) stress the importance of this pathway in the context of a systems biology approach to pharmacogenomics.” (Kohl, 2012) “Naftolin…
