Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.

It's always been a dream of mine, of exploring the living world, of classifying all the species and finding out what makes up the biosphere.

Far more important throughout the rest of science is the ability to form concepts, during which the researcher conjures images and processes by intuition.

Individual versus group selection results in a mix of altruism and selfishness, of virtue and sin, among the members of a society.

The paradox is that, by children taking shortcuts through computer games, through fantasies, through movies that load on all the emotional stimulation of encountering life in a stylized way - all of this is the equivalent of mainlining of paleolithic emotions, emotions about combat, about personal success, about overcoming monsters, about making powerful friendships, about winning wars and entering new territory.

So, the ant way of life is very ancient and very successful. As far as human beings are concerned, we've been around for only one million years--too soon be sure.

Overall, the human brain is the most complex object known in the universe - known, that is, to itself.
