Summary: In two studies of human pheromones we linked a mixture of androsterone and androstenol to increased flirtatious behavior and reports of increased attraction to the male wearing the mixture. This blog posts explains the reason for the use of…

Are viruses microRNAs? (2)

terrarium eco system

The role of microRNAs in cell type differentiation can be compared in the context of the role of viruses and mutations that cause cancer. Facts provide a basis for explaining the biological basis of epigenetically-effected cell type differentiation in species…

Evolution of Intelligent Viruses and Jumping Genes Conclusion: “…it is intelligent warfare between mobile genetic elements and the epigenetic responses of the cell that, most likely, determines evolution.” My comment: This conclusion appears to place biologically-based cause and effect into…

Nutrient-dependent pheromone-controlled ecological adaptations: from atoms to ecosystems My “…atoms to ecosystems approach continues to be based on some speculation, but it is largely based on experimental evidence, which comes from others who also have speculated about biologically-based cause and effect…
