The concept of Photosynthesis (building-up something using the Energy of light) is presently applied only to the plants kingdom. However the unraveling of the intrinsic property of melanin to split and re-form the water molecule breaks the paradigm. During a study about the three main causes of blindness initiated in 1990 in Aguascalientes, Mexico; Dr. Solis Herrera found the previously unknown capacity of melanin molecule to absorb photonic energy, dissipating it in a unique splitting the water molecule. The very first step of life in plants and humans is practically the the dissociation of the water molecule.
A comprehensive analysis of the importance of photosynthesis to life, and the importance of melanin to the process of photosynthesis.
Herrera's observations of the differences in mammals (including humans) and ascribing these the latitude of the natural environment (a function of the amount of UV light they are optimised to receive) were fascinating.
Whilst written from a scientific perspective, I was struck by the apparent implied symbiotic relationship between plants and animals in our use of the water molecule, and the symmetry of chlorophyll and haemoglobin. Certainly provokes thoughts about intelligent design underpinning life.
