I watched the following video where Dr. Swamidass tries to explain the genetic differences between humans and chimpanzees using the concept of Distance = Rate x Time, neutral evolution.
(41min).
There is a flaw in this argument. What that flaw concern is the meaning of beneficial, neutral, and detrimental mutations. Those adjectives for the word mutation concern reproductive fitness. A beneficial mutation increases reproductive fitness, a neutral mutation does not change reproductive fitness, and a detrimental mutation reduces reproductive fitness.
At this time, there are about 7.1 billion humans on earth.
At this time, there are about 300,000 common chimpanzees on earth.
The chimpanzee population size is about 0.0042% of the size of the human population size. Therefore, humans have vastly greater reproductive fitness than chimpanzees. If you want to claim that humans and chimpanzees evolved from a common ancestor, humans must have gotten some beneficial mutations along the way to give that vastly greater reproductive fitness. How exactly are these adaptive mutations accumulated to give this vastly greater reproductive fitness that humans demonstrate over chimpanzees?
