Local reorganization of xanthophores fine-tunes and colors the striped pattern of zebrafish

Excerpt: “Many animals have evolved a fascinating diversity in their color patterns, which serve as an essential component of their survival strategy.”

How the zebrafish gets its stripes: Uncovering how beautiful color patterns can develop in animals

Excerpt: These findings inform our way of thinking about colour pattern formation in other fish, but also in animals which are not accessible to direct observation during development such as peacocks, tigers and zebras,” says Nüsslein-Volhard — wondering how her cats got their stripes.

My comment: What they seem unable to clarify is the fact that cell type differentiation occurs via conserved molecular mechanisms that link nutrient-dependent amino acid substitutions to differences in morphological and behavioral phenotypes in all species. If they made that fact clear, others would realize that no evolutionary events can possibly be involved in what are obviously links between ecological variation and ecological adaptations that must occur during life history transitions.

Cell type differentiation occurs in immature forms that leads to cell type differentiation in mature organisms via nutrient-dependent pheromone-controlled epigenetic effects detailed in insects by Elekonich and Robinson (2000) and by Elekonich and Roberts (2005) using the model of biologically based cause and effect from our 1996 review published in Hormones and Behavior.

Now see: Artificial selection for structural color on butterfly wings and comparison with natural evolution Taken together with what you have just learned about zebrafish color, does it make sense that color differences in cell types somehow ‘evolved’ in 6 generations?(NO)

Does it make sense that color differences manifested in the different colors of cancerous skin cells are due to mutations? (YES)

Does it make sense that mutations cause color differences in the cell types of species that somehow evolved? (NO)

Are theories about mutations, natural selection, and the evolution of biodiversity supported by experimental evidence of biologically-based cause and effect (NO):

“We cannot conceive of a global external factor that could cause, during this time, parallel evolution of amino acid compositions of proteins in 15 diverse taxa that represent all three domains of life and span a wide range of lifestyles and environments. Thus, currently, the most plausible hypothesis is that we are observing a universal, intrinsic trend that emerged before the last universal common ancestor of all extant organisms.” Jordan et al (2005)

Please tell evolutionary theorists to start making sense of their ridiculous theories by providing experimental evidence of cause and effect, or to stop touting their pseudoscientific nonsense.
