——advantageous gene appears and quickly spreads through the population. ——
The gene doesn’t spread through the population. The population with the gene grows because it is favorable and is transmitted widely over time
It is a gene, not a virus
Uncertainty is the mark of a keen mind
Yes, of course it is “rare”. Just the latest part of evolutionary theory to come into question.
Where is the list of beneficial mutations that connect our common ancesters to both chimps and humans? That should be an obvious outgrowth of genome mapping. If evolution is true, there must exist a series of trivial mutations, starting with the common ancester, each of which is a viable and reproducable creature.
Otherwise, you can’t get from “there” to “here”. It’s like Google giving you directions from Japan to China.
