Since 1992, Kohlian facts have been used in attempts to overcome the misrepresentations of evolutionary theory that bastardized Darwin’s works. Since 2012, these Kohlian facts have been represented in at least four different published articles. In addition to my own published works, I’ve seen other relatives from an unknown Kohl lineage contribute to what theorists are now forced to consider.
For example, see these articles for information how the metabolism of nutrients to pheromones that control the physiology of reproduction accurately represents biologically based ecological adaptations sans mutations.
1) Kohl, Johannes et. al. (2013) A Bidirectional Circuit Switch Reroutes Pheromone Signals in Male and Female Brains
2) Kohl, Kevin D (2012) Diversity and function of the avian gut microbiota
Clearly, there will be more to come from James V. Kohl and other Kohls.
Nutrients are the ecological variable that we already know links the diversity and function of gut bacteria in vertebrates and invertebrates to the metabolism of nutrients to species specific pheromones that control the physiology of vertebrate and invertebrate reproduction via conserved molecular mechanisms. Hopefully, there is no reason to keep that information in the family.
