All offspring have different genes from their parents. In history there has not been one child with the same genome as its parents. Genomes don't change overnight. They evolve over time.
But if he was looking for a mate, the improbability is still a real stretch.
Not a valid point in genetic science. Human children share the same genome as their human parents by definition - since they are in the same species.
I put the word fertile in my question for a purpose. In my question the newly evolved offspring has to produce viable gametes, and those gametes have to find a compatible gamete. IF ya don’t share the same genome, (ie in the same species) ya ain’t gonna produce viable offspring or fertile offspring.
In the classic example ‘we evolved from chimps’ - there are key chromosomal differences between humans and chimps (different species) that reliably preclude fertilization/implantation and the growth of a viable embryo - let alone produce a fertile offspring.
Demonstrable, reliable speciation by evolution is a key missing link in the modern model of evolution. Darwin thought he saw it in the phenotype. We can’t make it work in the genotype.
So lets go with your argument for a bit. By pure chance, ONE human offspring evolved in the moment of fertilization in a chimpanzee - a new, unique zygote. Then that weird offspring was not rejected by its parents, grew to the age of sexual maturity and by some amazing mathematical and genetic coincidence, ANOTHER human was born in the same geography and time span, with the exact same random recombined DNA and chromosomal structure, and managed to find human #1, mate and produce a viable population (without God’s help).
Yeeaaah, I can go with that.
And when they have different numbers of genes, then what?
I know what happens when human children have a different number of genes than is normal for humans, and it is NEVER good.
So explain how the numbers of genes could change over time to produce the variety of life we see on the earth today.
