No understanding of biodiversity

No single explanation for biodiversity in Madagascar

Excerpt: “The study is part of a larger body of research aimed at identifying the climate, geology and other features of the environment that help bring new species of plants and animals into being in an area, and then sustain once they’re there.”
My comment: Like many studies, this one posits that new species automagically arise and are somehow sustained in ecological niches.
Excerpt: “What governs the distribution of, say, a particular group of frogs isn’t the same as what governs the distribution of a particular group of snakes,” Brown said. “A one-size-fits-all model doesn’t exist.”
My comment: Apparently, these researchers do not understand the fact that RNA-directed DNA methylation links the epigenetic landscape to the physical landscape of DNA in the organized genomes of all species via conserved molecular mechanisms that lead to ecological, social, neurogenic, and socio-cognitive niche construction manifested in increasing organismal complexity. Alternatively, they want others to believe there is no model of how nutrient-dependent pheromone-controlled biodiversity arises. For example, see: Nutrient-dependent/pheromone-controlled adaptive evolution: a model. “Minimally, this model can be compared to any other factual representations of epigenesis and epistasis for determination of the best scientific ‘fit’.” If the model is ignored, the claim can be made that one model links nutrient uptake to RNA-mediated biodiversity doesn’t exist.
Excerpt: “…each group of animals experiences its environment in a way that is unique to its life history and other biological characteristics,” Yoder said.”
Cell type differentiation in each individual of all groups of animals is nutrient-dependent. RNA-mediated events leads to amino acid substitutions that differentiate all cell types in all tissues of all organs in all organ systems that arise in the context of the pheromone-controlled physiology of reproduction that links biodiversity from ecological variation in nutrient availability to ecological adaptation via reproduction.
Abstract excerpt: A necessarily complex model to explain the biogeography of the amphibians and reptiles of Madagascar
“We conclude that patterns are influenced by a combination of diversification processes rather than by a single predominant mechanism. A ‘one-size-fits-all’ model does not exist.”
My comment: The model of nutrient-dependent pheromone-controlled RNA-mediated biodiversity has existed since 1996. It has been used to explain all biodiversity in the context of systems biology and niche construction based on details of conserved molecular epigenetics: “Small intranuclear proteins also participate in generating alternative splicing techniques of pre-mRNA and, by this mechanism, contribute to sexual differentiation in at least two species…” There is no other way that cell type differentiation occurs in any cell of any species.

“Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans (Keller et al., 2007; Kohl, 2007; Villarreal, 2009; Vosshall, Wong, & Axel, 2000).”
