Living being have gone a process of natural selection for million of years, in which those with characteristics are the one that survives. So, is emotion vital for survival, apparently yes, specially with mammals and birds.Mammal mothers let the young suckle on their body, the youngters in return feel a desire to bond and stay near them.In the wild mammals that fail to bond with their mothers rarely survive for long. It is evident that love among mother -infant is required for all mammals.

Does animals have emotions?

With that result we can say that mammals can't live with food alone. They have emotional needs to. Evolution imprinted them with the assumption that emotional needs are formed with soft furry things than with hard metallic objects. Alas, the cloth-mother never respond to their affection thus they grew up to be neurotic and asocial adults.With these experiments done, animals have emotional needs should be addressed, but I don't see that happening with the billions of animals in dairy industries.

Is everything now solved?

Freudian theories argued that relationship between children and parents were shaped by material feedback; children needed food, shelter, and medical care, so they bonded with their parents because they provide these needs.

Material feedback

In 1950s and 1960s, Harry Harlow conducted an experiment on infant monkeys separated from their mothers after birth. When given a choice between a metal dummy-mother fitted with milk bottles, and a soft cloth-covered dummy with no milk, the babby monkeys clung to the barren mother for all they are worth.

Official U.S. edition with full color illustrations throughout. NEW YORK TIMES BESTSELLER Yuval Noah Harari, author of the critically-acclaimed New York Times bestseller and international phenomenon Sapiens, returns with an equally original, compelling, and provocative book, turning his focus toward humanity’s future, and our quest to upgrade humans into gods. Over the past century humankind has managed to do the impossible and rein in famine, plague, and war. This may seem hard to accept, but, as Harari explains in his trademark style—thorough, yet riveting—famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda. What then will replace famine, plague, and war at the top of the human agenda? As the self-made gods of planet earth, what destinies will we set ourselves, and which quests will we undertake? Homo Deus explores the projects, dreams and nightmares that will shape the twenty-first century—from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus. With the same insight and clarity that made Sapiens an international hit and a New York Times bestseller, Harari maps out our future.
