As anyone who has spent time with cats knows, our feline companions are mysterious – much more so than other furry family members. Cats are much more similar to their wild ancestors than dogs are to wolves, so dogs are the more domesticated in that sense. of two kinds. As cats adapted to living alongside humans, they became more sociable with each other and much more accepting of humans, but there is no evidence that they have changed much over the past several thousand years.

Dogs and Cats dogs belong to a group of mammals known as Carnivora, and the wild ancestors of both species ate primarily meat. Recent DNA analyzes show that dogs acquired more copies of the so-called amylase gene during their development, which creates an enzyme that helps break down starch. Having more copies of this gene allowed dogs to eat a more omnivorous diet. In contrast, the family of cats, known as the Felidae, lost the genes that code for several key enzymes—including those that produce vitamin A, prostaglandins, and the amino acid taurine—early in their evolution. While dogs (and humans) can synthesize these substances from plant precursors, cats must obtain them from meat. To expand their diet, cats would have to develop physiological traits that allow them to synthesize these and other key nutrients from plant foods. This ability did not appear in the 10 million years of cat evolution, so it seems unlikely that it would have arisen spontaneously in our domestic cats.
