This study re-examines evolutionary biology by focusing on cellular communication, proposing a new cellular communicative-molecular approach to understand life's origins and the evolution of complex physiology from unicellular organisms.
Area of Science:
- Evolutionary Biology
- Cellular Physiology
- Origin of Life
Background:
- Traditional evolutionary theory faces challenges regarding the origins of life and teleological thinking.
- A focus on cellular communication offers a different perspective on evolutionary development.
- The cell's role as a communicative unit is central to understanding evolutionary processes.
Purpose of the Study:
- To propose a cellular communicative-molecular approach for understanding evolutionary biology.
- To re-evaluate the origins of life and the evolution of physiology from a cellular perspective.
- To establish a predictive framework for the evolution of complex physiology.
Main Methods:
- Analyzing evolutionary development through cellular communication and molecular interactions.
- Tracing vertebrate physiology from unicellular origins rather than phenotypic traits.
- Applying first principles of physiology based on cellular properties.
Main Results:
- The cellular communicative-molecular approach provides a logical evolutionary narrative.
- Viewing cells as information-processing units explains problem-solving in evolution.
- Complex physiology evolved from unicellular organisms through cellular communication and adaptation.
Conclusions:
- The study offers a robust, predictive model for the evolution of complex physiology.
- Physiological principles can be determined from fundamental cellular first principles.
- Evolutionary creativity arises from boundary conditions enabling adaptation to environmental challenges.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...
