The long period of immaturity suggests that in spite of humans’ opinions about other animals brains, north Atlantic sharks spend of lot of time learning before sexual maturity.
The parallel is the greater degree of enforced delay of “virtual” sexual maturity human societies have placed on “young adults”, over time, as “more advanced” learning seemed necessary for the more complex human societies.
Science is discovering numerous animal species have been doing the same thing, naturally, and not just “virtually” but actually, and due to various changing conditions, in their own case. The successive generation(s) have delayed sexual maturity, had fewer offspring but had more successful offspring by apparently learning how to cope better with changes the species encountered. They get a longer period of learning before reproduction and seem to have better survival strategies when they do start reproduction.
I am not sure what THAT says in the case of the north Atlantic sharks, other than the later sexual maturity does suggest “more learning” time was naturally deemed important. How that is triggered, versus how humans have intentionally triggered it is something I do not have an answer for.
Wow, while what you wtote sounds well thought out it’s a load of...... The sharks do not delay mating, nothing you said has any substance.
If you believe evolution it violates everything you wrote.
