Are there better alternatives to capitalism?
When did farm animals stop being seen creatures that feel pain and anguish and began to be treated as machines?

But no, Homo Sapiens belong to the hominid family. Our closest living relatives are from that family: chimpanzees, bonobos, gorillas, and orangutans.

 

Apart from sapiens, today there are no other living animals within the Homo (human) genus, but in the past, there were other species of this genus. Some of those humans left Africa and colonized other continents. Humans in Europe and Western Asia evolved into another genus.

 

Thus, from about 2 million years ago to about 10,000 years ago, various human species coexisted in the world. All of them had important common characteristics. The most notable is that they all had a large brain in proportion to their weight. A large brain expends a lot of energy: it is 2 or 3% of body weight but consumes 25% of energy (at rest).
