Each new layer of Life is the result of what scientists call a major evolutionary transition? What was the cause of these transitions the answer is? Cooperation a Major Transition starts when free living creatures team up to form a cooperative group in the early stages of cooperation Participants are free to come and go as they [please] [if] a group sticks together long enough however 00:04:51 Division of labor will often evolve different participants begin specializing in different tasks as time goes on Individuals may become so specialized that they can no longer survive on their own [if] the entire group becomes locked into cooperation Depending fully on one another to survive and reproduce a new super organism has been forged and they made your evolutionary transition is complete 00:05:16 From this point on the entire group will evolve together as one Models describing natural situations that might promote the evolution of major transitions have been put forth by scientists such as John Maynard Smith [fior] Sonck Mary stuart West and w d hamilton using these models Researchers have been able to Mimic natural scenarios in the lab Allowing us to directly witness the beginnings of major transitions [evolved]
This is the key to Major Evolutionary Transition - a population of free living individual creatures discover that in teaming up, there is a greater resultant evolutionary fitness, mutualism symbiotic relationship emerges. It becomes so strong over time that the many become a self-replicating one.
The biological self is always defined by a boundary between inner and outer, but in this act of mutualism, the many biological selves join to form a new higher order biological self.
In this way, a multi-cellular species like ours is somewhat like one of those nested Russian dolls.
Indeed, Amanda Robins hypothesizes
that our species has undergone what she and Peter Nonacs calls Major System Transition (MST). The cultural artifact of inscribed language has made possible a superorganism / supraorganism that has spread across the globe.
