Every scientific theory has a philosophical substratum, including experimental schemes. In a theory of evolution, directly related to the concept of life, this duality is more openly apparent. However, it is irrelevant for scientific and technological purposes.

The Conditional Evolution of Live –CEL– is conceptually closer to vitalism, Lamarckism, and Mendel’s ideas than to the emergentism of Darwin and determinism. The book includes criticism of Creationism, Intelligent Design, Darwin, Neo-Darwinism, and Synthetic theory.

The CEL configures an alternative, scientific, and evolutionary theory. It suggests an internal mechanism of improving living beings that use many systems, methods, or procedures depending on each case and its particular conditions.

The thoughts on evolutionary biology orbit around the objectives and causes of transmitted genetic information and how these changes passe on to descendants.

The CEL explains how and when genes are dominant or recessive; i.e., the significance in genetic expression. It also identifies the main advantages of sexual differentiation and explores the concepts of gene, genome, DNA, and variability.

Besides, it allows a better understanding of the origin of humanity, anthropology, and the recent human historical evolution.
