| + | Many major evolutionary transitions evolve a transition from a '''group of organism''' to a '''group as organism''', for example the transition from [http://en.wikipedia.org/wiki/Prokaryote prokaryotes] to [http://en.wikipedia.org/wiki/Eukaryote eukaryotes], from unicellular eukaryotes (green or red algae) to multicellular eukaryotes (animals, plants, fungi), and from humans to societies. Eukaryotes are organisms whose cells contain complex structures enclosed within membranes. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, within which the genetic material is carried. Simple eukaryotic organisms are for instance red and green algae. Examples for prokaryotes are bacteria. Eukaryotes evolved from prokaryotes more than 2 billion years ago. Eukaryotic cells probably originated as a group or community of prokaryotes. | ||

| + | == Transition between ecological and economic systems == | ||
| + | |||
| + | The connection between ecological and [[Economic_system|economic systems]] is interesting, too. | ||
| + | Both systems can be viewed as | ||
| + | [[Complex_Adaptive_System|complex adaptive systems]] | ||
| + | consisting of many interacting agents that adapt and learn | ||
| + | from their interactions with one another. | ||
| + | One major difference is perhaps what the | ||
| + | agents do with their supply, the agents | ||
| + | of ecosystems are more "selfish": | ||
| + | |||
| + | * Organisms consume s.th. to produce more of themselves, they maintain themselves with food, and they produce stuff necessary to make more copies of themselves. Agent and product are identical. | ||
| + | |||
| + | * Companies consume s.th. to produce a product which is different from themselves. Agent and product are different. | ||
| + | |||
| + | There is a fundamental difference in the input-output | ||
| + | relations in economic and ecological systems. | ||
| + | The output of agents in economic systems is | ||
| + | a product made from the inputs during the | ||
| + | business process. In ecologic systems this is | ||
| + | only comparable to the cognitive part of | ||
| + | organisms, where perceptions are processed to | ||
| + | produce an action. In the "food web" there is | ||
| + | nothing produced except the organisms themselves. | ||
| + | Whenever there is something interesting happening | ||
| + | in nature, it is either supper time or pairing | ||
| + | time. The former is used to sustain the body, | ||
| + | the latter to sustain the species. | ||
| + | |||
| + | The Neolithic Revolution | ||
| + | is a kind of major evolutionary transition between ecology | ||
| + | and economy, see also the corresponding | ||
| + | [http://en.wikipedia.org/wiki/Neolithic_revolution wikipedia entry]. | ||
| + | The first economic systems emerged in ecological systems | ||
| + | when hunters and gatherers became farmers and cattle | ||
| + | breeders. In a sense, economic systems are as old as | ||
| + | civilization and agriculture. Farmers are located | ||
| + | at the intersection of ecological and econmic systems, | ||
| + | because they produce organic products by controlled | ||
| + | growth and domestication. They act like a company or | ||
| + | organization which produces industrial products which | ||
| + | are sold on markets, but the products themselves are | ||
| + | organic and completely embedded in the ecological | ||
| + | system. | ||
