But there is only one living creature. Species are only several steps of genetic diversity away from each other. We differentiate one species from the next because they can't mate. That's it. But that just reflects their distance from each other in the nodal network. They are all the same. — MikeL
There is a mass movement to turn robots into humans too, so maybe they'll meet in the middle somewhere. Bionically limbed, digitally minded, arguing between the two who is the more real. — MikeL

, there are not billions and billions of different lifeforms on earth, there is only one organism covering the adaptive landscape like a mat. — MikeL
. This would require that every mutation was either positive or neutral. There could be no negative mutations, as this would wipe out the organism — MikeL
Every variant in the population is either more suited or less suited to its environment or has not net change — MikeL
I'm far from being an expert — Srap Tasmaner
Oh, do you mean differentiated in the meaning of differential equation? — MikeL
There isn't a one-to-one map between an organism's features and its genome. — Srap Tasmaner
Should also have explicitly said there's not a single genome to find its way around the valley. You get whatever you get when some part of the population's gene pool makes it over there. — Srap Tasmaner
However because the landscape is multidimensional, paths closed off by speciation in one dimension may open up paths along other dimensions. What is at stake here is the creation of new possibilities. In other words, the adaptive landscape is not just a series of possibilities but a series of changing possibilities, which are themselves dependent upon the actual paths of speciation. Because these paths themselves are contingent (upon the changes in actual environment), the adaptive landscape cannot be seen as a simple set of pre-existing possibilites which are then realized by the random walk of evolution or not. Possibilities themselves are subject to change such that the landscape evolves along with the species that populate it.
This is why I think the checkerboard-of-lights image is not quite right: such a image locates change only at the level of the species, which move across a board of fixed lights. The trick is to imagine the lights themselves warping the board as they flicker across it. Again at stake here is the necessity to secure the the possibility of novelty: if the board is fixed, it becomes possible, in principle, to exhaust the 'combinations' of lights turned on and off across it. But evolution is not just a matter of combinatorics: one must think the coming-into-being of the network itself. — StreetlightX
I understand what you mean. The adaptive landscape is itself changing through time, throwing up troughs and waves. Evolution tries to run the rise of waves. Because we can think of life as starting at Point A, we can see that it is an expanding sphere. An expanding sphere is constantly expanding its Surface Area as it expands radially. New combination of genotypes come into existence to cross the new expanse. — MikeL
I wonder what type of force could act like that on the genome that is not a maxima or minima? — MikeL
