Humans have been trying to domesticate animals for thousands of years. We’ve taught dogs how to fetch the paper, cats how to use litter boxes, and horses how to pull carts since ancient times. The efforts have paid off in many ways humans benefit from having well-trained workers, such as farmhands or soldiers, while pets provide companionship and entertainment.
However, there are still plenty of animals that people don’t want around them, like cockroaches or mosquitoes. And even those they do desire can be difficult to tame.
“Domestication is a complex trait,” says Dr. Steven M. Calle, professor emeritus in the Department of Biological Sciences and director of the Center of Excellence for Aquatic Research at Embry-Riddle Aeronautical University. “It takes time and effort.”
Calle has studied the genetics of dog breeds extensively, but he also believes that all animals possess their own unique attributes that make them more or less suitable for domestication.
For example, he notes that wolves tend to be aggressive toward strangers but not toward members of their own pack. In contrast, dogs are very social and friendly with other dogs but often wary of everyone else. On top of these innate characteristics, however, human societies also play an important role in shaping which animals thrive best among us.
In this article, we’ll look at several types of animals that humans consider our friends and why some are easier to turn into household pets than others. First up: the most popular pet on Earth.
The first thing that comes to mind when you think about getting a puppy or a new dog is love. But what kind of love? Some people prefer a playful pooch who will run through the house after balls or chase cars down the street, while others seek out a loyal friend who won’t leave their side no matter where they go. Regardless of your preferences, though, one thing is clear: It’s tough being a dog.
First, dogs need lots of exercises so they can burn off excess energy. They must also be exposed to sunlight (which helps regulate their body clock) and fresh air (to help control odors). This means spending time outside every day.
Next, they require a diet rich in protein, carbohydrates, and vitamin D, as well as adequate water intake. Finally, they require constant attention from their owners, especially during playtime. All of these requirements put …
