Mankind has wrestled with the questions of evolution, species diversity, and mass extinctions since the dawn of modern science. Now, 151 years after Charles Darwin published On the Origin of Species, a retired physician/clinical investigator has solved the mystery of natural selection.

Offering a thorough explanation of the process of natural selection and evolution at the molecular level, prolific author and scientist Dr .Julian Lieb shows that the enzymes of the arachidonic acid cascade regulate genes, proteins, other enzymes and stem cells.

Prostaglandins, the primary products of the cascade, regulate cell-to-cell signaling, the shape and form of cells, cell replication, and the movement of cells and other mechanisms involved in the formation of the embryo.

Natural selection differentiates between reproduction and infertility, survival or death and extinction, and Dr. Lieb has shown that prostaglandins have these paradoxical properties.

Darwin reasoned that natural selection acts on variation. In 1977, a colleague of Dr. Lieb’s showed that prostaglandins regulate nucleic acids (DNA and RNA), and Dr. Lieb has taken this a step further, in showing that prostaglandins subserve natural selection and nucleic acids variation.

A fascinating, absorbing, and altogether revelatory treatise on the nature of disease and evolution, Dr. Lieb’s newest is a
tremendous leap forward in the fundamental understanding of our world as we know it. Accessible and easy to understand, Mass Extinctions: Nature’s Spectacular Stagings of Natural Selection is a groundbreaking look at the essence of life and the future of medicine.
