Cooperation not competition underpins evolution
Stumble It!A significant body of research into evolution now indicates that survival of the fittest is only a part of the story. Life did not take over the globe by combat but by networking!
That is according to Prof. Lynn Margulis, distinguished biologist and Presidential Medal of Science Winner 1999
Recent scientific discoveries [1] are showing that evolution is more about collaboration between organisms and species than it ever was about competition. For example, the New Scientist (April 2005 issue) has published its Top Ten of "Evolutions Greatest Inventions":
- Multicellularity
- The Eye
- The Brain
- Language
- Photosynthesis
- Sex
- Death
- Parasitism
- Superorganisms
- Symbiosis
Included at Number Ten is Symbiosis (defined as two species engaging in physically intimate, mutually beneficial dependency) which the New Scientist declares, "has popped up so frequently during evolution that it is safe to say it's the rule, not the exception".
Also making the top ten is the "Superorganism" covering those social species like ants and bees which operate collectively. The article describes a lesser-known superorganism - the Portuguese man-of-war Jellyfish. Although it looks like a one- tentacled individual is in fact a colony of single-celled organisms. According to New Scientist these superorganisms are probably "the closest thing on earth to utopia"
Its also enlightening to notice that three of the other top ten (Multicellurity, Parasitsm, Symbiosis) specifically involve co-operation (sometimes unwitting) between species.
Also the remaining six inventions all validate nicely the simple model of a living system adapted from Maturana (A Design Framework for Bioteams)[2].
Sex, Death (that is programmed cell death!) and Photosynthesis (capturing energy from sunlight) are all Processes within a living system, the Eye and the Brain are key aspects of the Nervous System and finally Language is that ability generated by the nervous system for a living system to recurrently communicate with other living systems.

Mobile business applications framework
In a just published book Work Goes Mobile by Michael Lattanzi, Antti Korhonen and Vishy Gopalakrishnan, authors of Nokia’s mobility master plan, propose a very useful application profiling scheme to establish the degree to which a business could exploit mobile technologies in their broadest sense. This approach would also be very useful for establishing the support requirements for virtually networked teams.

Design better social software using Living Systems Theory
With the explosion in social software and the recognition that these types of systems need to reach critical mass to survive and prosper it is amazing that so few people seem to be applying the well-established philosophical principles of living systems (autopoiesis) to design for sustainability.
Bioteams Practitioners Network: Update
I would just like to thank the many people who expressed their interest so enthusiastically in The Bioteams Practitioners Network and to let everyone know I have their contact details and will arrange a time to talk before the planned launch in the New Year. Also if you missed it here is the link to the original post. Best Regards Ken Thompson
