[Animals] When animals change their lifestyle to avoid humans


Recommended Posts

Several years ago, zoologists noticed a remarkable change in the behavior of wild animals in the forests of Africa and other parts of the world. After the antelopes were roaming their areas during the day, their behavior changed now so that they began to go out more at night in search of food, and a similar transformation occurred in mammals known to be among the animals that hunt at night.

In Mozambique, scientists from the University of California, Berkeley, led by Dr. Caitlin Gaynor, noticed that elephants began to travel under the cover of darkness, when the roads were relatively free of people, and they remained in the forest during the day.

In Nepal, tigers were often active in the moonlight when people were asleep.

In Poland, wild boars living in a national park divided their days equally between waking and sleeping, while urban pigs were barely awake except at night.

Gaynor and her colleagues linked these behaviors to evidence of nocturnal shifts in dozens of species of animals that regularly come into contact with humans, in a study published in June on every continent except Antarctica. The researcher believes that these behavioral changes bring with them a rapid evolutionary change as well.

The study, which scientists called "human evolution", took about twenty years, as evidence indicates that humans were deliberately mani[CENSORED]ting plants and animals to bring out the preferred traits for ages (as the first evidence refers to the evolution that occurred with some types of dogs such as beagles, mastiffs, and Chihuahuas).


Gaynor found that some non-lethal human activities, such as walking and hiking in the woods, terrify wild animals as much as hunting does, and she believes that as nocturnal behavior becomes more established, more radical adaptations can follow, such as mammals acquiring features suitable for navigating in the dark, such as The widest eyes, the most sensitive ears, and the most powerful sense of smell.

Gaynor notes that changes in one species are likely to increase changes in others. For example, the red chaden (a type of deer) in Argentina has learned to avoid hunters by foraging at night, which reduces competition with other species of its own kind.

Indeed, research shows that some coyotes in California have adapted themselves to hunting at night and are getting used to catching nocturnal rodents that they used to eat little, and that some nocturnal prey are likely to become more active during the day, using humans as "temporary shields" against predators.
