Growing up human is uniquely a matter of social relations rather than biology. What we learn from connections within the family takes the place of instincts that program the behavior of animals; which raises the question, how good are these connections?

I'd been interested in animal behaviour as a teenager and had thought of studying it at one point.

I've always been interested in animal behavior, and I keep reading about it because it's so surprising all the time - so many things are happening around us that we neglect to look at. Part of the passion I have for biology is based on this wonderment.

The ways in which people treat animals will be reflected in how people relate to one another.

It has been generally the custom of writers on natural history to take the habits and instincts of animals as the fixed point, and to consider their structure and organization as specially adapted to be in accordance with them.

It is an incontrovertible fact that if we want to make progress in basic areas of medicine and biology, we are going to have to use animals.

Disease is not the prerogative of man and the domestic animals, so it was quite natural to see if the lower animals, with very simple organizations, showed pathological phenomena, and if so, infection, cure and immunity could be observed among them.

People are powerfully moved by imagination, belief, and knowledge. They can consider the past and future. They can make changes in their behavior out of reason in a way that animals can't do.

The information that is passed from person to person and from generation to generation is the primary factor that gives humans a competitive advantage over other animals.
