The biologically-based origin of the mammalian placenta

The past is not the key to the present

Summary: In this open access journal article, Gunter Wagner’s group eliminates assumptions about mutations and ends the obfuscation of biologically-based cause and effect. Experimental evidence links ecological variation via non-living viruses to ecological adaptations manifested in the biodiversity of morphological…

Sex determination via conserved molecular mechanisms

1) Structure–function analysis of mouse Sry reveals dual essential roles of the C-terminal polyglutamine tract in sex determination (2014) Excerpt: “We demonstrate, using a combination of biochemical, cell-based, and transgenic mouse assays, that this domain plays essential roles in both protein stabilization and transactivation of…

Human Pheromones and sex differences in brain maturation

The effect of GnRH on secretion on luteinizing hormone/follicle stimulating hormone ratios and steroidogenesis, links social odors to brain maturation across species of mammals, as well as vertebrates. Experience-dependent brain-directed behaviors should be as variable as would be expected by the association between food odors and food preferences.
