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 c
