Speaking of species extinction
What if evolution is a game of Highlander?
Seriously speaking we can talk about certain aspects of evolution but what if the end game of this arbitrary system always trends towards a few dominant species? And then that is unstable and speciation starts all over again?
For whatever reason the pattern of life appears to be a speciation event followed by a selection of a much smaller number of dominant species and then another speciation event and reduction of species. We have had at least three of these and maybe a fourth.
In analogous models the narrowed range of options results in a chaotic collapse into a large number of unstable states. It will be 50 to 60 years before we can model the Earth's genome and play out options but just for the eastwhile SF authors among us what if the rules of evolution do result in "There can be only one" as the result? Eventually, should a star last long enough that could be the result of evolution. That would be the appearance of a single species for an entire planet.
What this might be like I have no idea. I would guess it to be something like Brian Aldis's banyon tree without the other species intruding.
Jews stole the land. The owners want it back. That is all anyone needs to know about Israel. That is all there is to know about Israel.
