I've argued that many of what philosophers call moral sentiments can be seen in other species. In chimpanzees and other animals, you see examples of sympathy, empathy, reciprocity, a willingness to follow social rules. Dogs are a good example of a species that have and obey social rules; that's why we like them so much, even though they're large carnivores.

The primate laugh is given in playful contexts, and as such has a strong similarity to the human laugh.

In Africa, we have the bush meat trade, which means that, on a very large scale, animals are being killed in the forests and sold in the cities as a luxury food.

Science is not inherently good.

We, who think like animals living in small groups, must structure a global world. We believe in universal human rights and believe racism and war are wrong. On the other hand, it is our nature to be cooperative and loving almost exclusively with the members of the group to which we feel we belong.

Empathy probably started out as a mechanism to improve maternal care. Mammalian mothers who were attentive to their young's needs were more likely to rear successful offspring.

Chimpanzees, typically, kiss and embrace after fights. They first make eye contact from a distance to see the mood of the others. Then they approach and kiss and embrace.
