When it comes to the hypothesis of whether sharks can "run away when they see a human", we seem to be caught up in a complicated discussion. From shark-human interactions, to the evolution of animal behavior, this topic touches on the impact of humans on the natural world and our intervention in animal behavior. But is it really realistic to make sharks fear human attacks?
To make sharks scared of human attacks seems to be a bit like a pipa half-covering their faces. Considering human-dog interactions, we understand that domesticating a wild animal requires a long period of patience and interaction, which is the result of evolution. Wolves have found food in human-inhabited areas, which became the starting point for their domestication into domestic dogs. Wolves have evolved into human-friendly pets, a time-consuming and labor-intensive process that requires long-term interaction and care.
For sharks, it takes a series of "blows" to make them fear human attacks. This is not an overnight task. We need to clash with sharks in a specific area, damage them, and let them escape. This repetitive process may leave a "fear of humans" mark in the shark's genes.
However, this approach requires extreme caution. We can't hurt the sharks too hard, or it could lead to their death. But at the same time, the damage should not be too slight, otherwise the shark may not be afraid. This requires a lot of money and professional "master fishers" to implement.
But how long does it take to get the shark in fear? This evolution doesn't happen overnight. Unlike the domestication of dogs, this takes tens of thousands of years. Sharks also have a long growth cycle, with some taking up to 150 years to reach adulthood, which means that it takes at least thousands of generations to leave this "fear of humans" trait at the genetic level.
In addition, for sharks to evolve, a large number of sharks need to appear at the same time. However, about 100 million sharks are killed by humans every year. Even with so many sharks being killed, they didn't evolve the genes to fear humans. This suggests that simply harming sharks will not work, and that the extent of the damage must be controlled.
So, it's very difficult to get a shark to hurt, but not to be fatal. Such a "blow" is only the beginning, and it will take a long and continuous "battle" with the shark.
To sum up, it takes a long time and conditions for a shark to develop a fear of humans. Such a monumental feat requires not only long-term evolution, but also a lot of money and expertise. So, while theoretically possible, in practice the cost and efficiency are extremely low, which does not seem to be a viable attempt.
The interaction and evolution between humans and sharks largely needs to follow the laws of nature. Human intervention needs to be treated with caution in the evolution and evolution of animal behavior, after all, the path of evolution is not something we can manipulate at will.
