Spontaneous Evolution - Learning From Our Cells

"You know, our cells just might be smarter than we are". Swami Beyondananda. "How can 50 trillion cells live in harmony and peace while a mere 7 billion people are on the verge of annihilating themselves?"

This is one of questions explored in the very interesting book I'm reading: 'Spontaneous Evolution' by Lipton and Bhaerman. They talk about the organizing principles responsible for the evolution of multi-cellular communities; their premise is that what works for the cell also works for the human, and what works for the human will also work for humanity.

The drive to higher efficiency and survivability led to the evolution of eukaryotic cells - communities of single prokaryotic cells. Over time, these evolved into close-knit cell colonies with individual cells performing essentially the same job.

As the population of these colonies exceeded a certain limit, it was no longer efficient for each cell to do the same job. Communal cells began to differentiate and specialize - delegating specific tasks to different cells.

Akin to craftsmen and their guilds, differentiated cells form tissues and organs whose products and services are required for the community's survival. For example, a cardiac muscle cell is a master of contraction - a process that is managed and driven by the many different organized guilds of cardiac cells that comprise the heart.

In exchange for their specialized cardio-vascular services, these cardiac cell guilds receive complementary services from other specialized cell guilds in the body - for example, nutrients from the digestive system, oxygen from the respiratory system, protection from the immune system, waste management through the excretory system and world news through the nervous system.

It's an important lesson: the success of these complex systems is a function of co-operation, not competition, among the cell guilds. The remarkable harmony displayed at the cellular level is the character that distinguishes successful cell communities from the current state of our human society. Each cell is an individual, yet they all behave and support one another.

A very interesting feature of the cell community is their equivalent of a monetary system. Adenosine Triphosphate (ATP) molecules are the currency of the cellular economy. Cells work to make ATP and expend ATP to do work.

Cells whose efforts are more vital get paid more ATP and may even be provided with cellular entourages that support their specialized functions. While cells are on different pay scales, every cell is provided with the basics of life: food, shelter, health care and protection.

Excess energy is stored in fact cells - the equivalent of regional and national banks. These reserves are available for the use of the entire community - at the behest of the body's government.

These reserves can be deployed anywhere within the system to build, upgrade, or repair the body's infrastructure. Cells, therefore, freely contribute to the efforts of the community without having to worry about where their next ATP paycheck will come from.

The human cellular organization has a R&D system that creates technology and manufactures biochemical equivalents of steel cables, plywood, circuitry and networks: an advanced environmental system for air and water purification; a superfast communication system right to the cell level; a criminal justice system that detains, rehabilitates and even assists in the suicide of destructive cells; full health care coverage and an immune system.

Will the Connected Age move towards true communities that collaborate will each other for the larger good? Will there be true interdependence as exemplified by our cellular communities? Do share your own thoughts and comments on this.

The New Constructs is an initiative to examine our beliefs and assumptions - about life and living - that we need to reinvent in order to create a more inclusive and sustainable world. It is an opportunity for each one of us to connect, collaborate and co-create the world that we will rebuild for posterity. Do post your own examples on the Wall.

Sudhakar Ram is Chairman and Co-Founder of IT solutions provider, Mastek. He believes that creating a sustainable world would require a shift in the "constructs" that drive our attitudes and actions.

The Greatest Show on Earth - The Evidence for Evolution

Book Review: The Greatest Show on Earth, The Evidence for Evolution by Richard Dawkins

Richard Dawkins most recent book "The Greatest Show on Earth" is a must read if you have to deal with people who do not believe in evolution!

This new volume supports the theory of evolution by natural selection. Once you have read this book you'll have a lot of data and facts to utilize in your next heated conversation on this sometimes controversial topic.

Dawkins texts on science were kept under wraps by the fame resulting from "The God Delusion". The people who do not believe in 'evolution' generally tend to be extremely spiritual and religious people which are sometimes at odds with his work, possibly also down to his previous work "the god delusion".

The author makes some bold statements, according to him if fossils had not been discovered, man would not have even considered evolution. Man would have not known the mysterious ways in which living things around us have evolved, the extinct living plants and animals and about how life existed thousands of years ago. Dawkins also takes into consideration molecular and radioactive dating, geological strata and plate tectonics, DNA sequencing, Darwin's voyages and the remarkable Lenski experiments with bacterial evolution demonstrating evolution.

Understandable, convincing, believable and easy are the words which can be used to describe Richard Dawkins writing style. Most people will be able to understand this book, although sometimes you have to read the passage twice before clearly understanding the topic. Even subjects like genetic science can be easily understood without prior knowledge.

Dawkins is the type of author who doesn't "dumb down" his material, he puts trust in his readers ability to understand him. At times his style of writing can also be humorous which is always good.

The Greatest Show on Earth is one of Dawkins masterpieces, perhaps the definitive book on evolution as well.
