About why Tibetan antelopes migrate
Zoology has a different view

One is genetics.
The old, the weak, the sick and the disabled are eliminated through migration, and the surviving winners continue to bear the mission of reproducing offspring and passing on genes.
The second is climate theory.
The cubs have a lower altitude and a better climate.
However, through actual observations, some cub-producing places, such as Zhuonai Lake, are not significantly superior in terms of climatic environment and habitat in June and July.
The third is food.
Some people think that the cubs are rich in water and grass.
After on-the-spot investigation, scientists found that the vegetation water source of Zhuonai Lake is not obviously superior.
Fourth, the natural enemy said.
In the calving area, the number of natural enemies of Tibetan antelope is small.
However, studies have found that natural predators such as wolves, brown bears and raptors will always follow the migrating flocks, so the breeding grounds are not safe.
Some researchers have put forward a new guess called
"collective memory"
: the current Tibetan antelope may not know why it is moving, but its mother and grandmother are leaving, so it is logical and thinks that it should go too.
In fact, the research conclusions on the reasons for the migration of Tibetan antelopes have been changing over the years, and there is still no accurate conclusion.
