Butterflies. Before we had flowers…
Visiting a colleague in Germany in 2012, Boston College Research Professor Paul K. Strother was examining soil samples for pollen, spores, pieces of plants and insect legs - organic debris that might otherwise have been considered "pond scum" when it was trapped in sediment during cataclysmic earth events 200 million years ago. The slides of…

True frogs… Ageing… False theories...
New research shows, in contrast to expectations, 'the rapid global range expansion of true frogs was not associated with increased net-diversification.' (1) And the examples of problems in the current evolution theory (Theory of Evolution – ToE) do not end here. As Charles Darwin explained, natural selection results in the fittest individuals for a given…

X, Y, Male, Female…
In most mammals, us included, biological sex is determined by a lottery between two letters: X and Y, the sex chromosomes. Inherit one X each from mom and dad, and develop ovaries, a womb and a vagina. Inherit an X from mom and a Y from dad, and develop testes and a penis. But there…

![Abre los ojos: Right-handed. Left-handed. It matters not… [Asymmetry is just a phenomenon]](https://harmoniaphilosophica.com/wp-content/uploads/2018/01/321244791d742638ded9ec4ea1f54a601-236x260.jpg)
Abre los ojos: Right-handed. Left-handed. It matters not… [Asymmetry is just a phenomenon]
Other people are right-handed and other people are left-handed. "Handed-ness" or left-right asymmetry is prevalent throughout the animal kingdom, including in pigeons and zebrafish. But why do people and animals naturally favor one side over the other, and what does it teach us about the brain's inner workings? Researchers explore these questions in a Review…

Changing color. Turing. Von Neumann. Automata. Thinking. Tautologies.
Skin colour patterns in animals arise from microscopic interactions among coloured cells that obey equations discovered by the mathematician Alan Turing. Researchers at the University of Geneva (UNIGE), Switzerland, and SIB Swiss Institute of Bioinformatics reported in the journal Nature that a southwestern European lizard slowly acquires its intricate adult skin colour by changing the…
