Evolution Definition: The ORIGIN of the SPECIES
Postulate: Natural Selection
Natural Selection: The Spanish introduced cattle into Texas abt 1700. A portion of those cattle were left to roam until abt 1850 and through natural selection produced a distinct new Breed of cattle, the Texas Longhorns.
Not a New Species..the Breed of Cattle, Texas Longhorns, were expressions of genetic code inherent in all cattle.
So selective breeding is not evolution. Origin of Species does not occur through natural selection.
I am not going to argue Natural Selection. It always occurs within species and is easily demonstrated through centuries of selective livestock breeding.
Natural Selection Is Not Evolution
Evolution is the Creation of Species. That has never happened through natural selection because the naturally selected genes must be present in the selected animal. Those animals must have the ability to interbreed, which is the very definition of Species..one unique species.
Postulate: Genetic Mutation
So we have Mutation as the mechanism of evolution or the Creation of Species.
Mutations are random and so far as we know, invariably destructive to the organism and/or the ability to survive.
There is the new theory "Mitochondrial Eve" whereby it is claimed that there was a genetic shift in the DNA about 200,000 years ago which "switched" ape to human.
However the more research that is done, the more muddied the waters.
So that is interesting BUT so far, evolution does not have a postulate other than "probably a random mutation that happened just because.
Evolution does not predict anything because evolution depends on a random mutation that may or may not happen or happened, who knows when or why.
It's not evolution that is flawed here; the issue is clearly your understanding of it.
If you'd like to improve your understanding of evolution, there are some free courses available here: Educational resources for learning about biology and evolution
To wit:
So selective breeding is not evolution. Origin of Species does not occur through natural selection.
Evolution, generally speaking, is simply a change in allele frequencies in a population over time. This does occur in selective breeding so by definition selective breeding is a form of biological evolution.
Mutations are random and so far as we know, invariably destructive to the organism and/or the ability to survive.
Vast majority of mutations are neutral. You have at least a few dozen novel mutations yourself.
There is the new theory "Mitochondrial Eve" whereby it is claimed that there was a genetic shift in the DNA about 200,000 years ago which "switched" ape to human.
That's not what Mitochondrial Eve is at all. Mitochondrial Eve is simply the last common ancestor on the female side for humans.
And technically speaking, we are still apes (specifically hominidae, aka the "great apes").
