Dogs are such cool animals. They were one of the first domestic animals and the most widely abundant terrestrial carnivore.
They are very nice! And they come in all shapes and sizes. It's hard to imagine the Chihuahua and the Great Dane come from the same ancestry.
I know what you mean! They were selectively bred over millennia which is how breeds came to be.
Did they originally come from wolves? I heard that before.
That's correct. They came from wolves and were bred for different behaviors and sensory capabilities.
Interesting. I always though it would be funny to imagine the Chihuahua surviving in the wild. But I guess they were once larger and more ferocious.
was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.
Their long association with humans has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species. Dogs vary widely in shape, size and colors. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and military, companionship and, more recently
animals. Humans determine which animal or plant will reproduce and which of the offspring will survive; thus, they determine which genes will be passed on to future generations. The process of artificial selection has had a significant impact on the evolution of domestic animals. For example, people have produced different types of dogs by controlled breeding. The differences in size between the Chihuahua and the Great Dane are the result of artificial selection. Despite their dramatically different physical appearance, they and all other dogs evolved from a few wolves domesticated by
