Once, it was believed that humans possessed around 100,000 genes.
Subsequent research, however, revealed that the actual number is only about 20,000 to 25,000.
Surprisingly, this is roughly the same as nematodes and mice, demonstrating that the sheer number of genes does not determine intelligence or evolutionary complexity.
When I first studied Darwin’s theory of evolution, I vaguely wondered:
“If goldfish eventually evolved into humans, wouldn’t the gene count be vastly different?”
At the time, I dismissed it as a naive thought, yet it turns out that intuition was not entirely misplaced.
It is not the raw quantity of genes but rather their network structures and regulatory mechanisms that define complexity and intelligence.
This paradox resonates with KEN Theory’s principle that “more is not necessarily smarter.”
