Science is not marginal. Like art, it is a universal possession of humanity, and scientific knowledge has become a vital part of our species' repertory. It comprises what we know of the material world with reasonable certainty. . . . Thanks to science and technology, access to factual information of all kinds is rising exponentially.

So important are insects and other land-dwelling arthropods that if all were to disappear, humanity probably could not last more than a few months.

Women are extraordinary in lacking the estrus, or period of heat. The females of most other primate species become sexually active, to the point of aggression, only at the time of ovulation. Why has sexual responsiveness become nearly continuous? Unusually frequent sexual activity between males and females served as the principle device for cementing the pair bond.

We have to create a sustainable environment, worldwide, and we're not doing it. The best thing we can do with the rest of this century is aggressively acquire - and put aside - the richest natural reserves that we can, and then do our best to manage the needs and desires of the 11 billion people we expect to have by the end of the century. This is where biology is headed. For that reason, the sooner we get on with mapping biodiversity on Earth, the better off biology will be - not to mention the whole subject of saving it before we carelessly throw it away.

These slender little people (Homo Habilis), the size of modern 12 year olds, were devoid of fangs and claws and almost certainly slower on foot than the four legged animals around them. They could have succeeded in their new way of life only by relying on tools and sophisticated cooperative behavior

The solutions like freezing zygotes, fertilized eggs, of all kinds of animals and so on, or keeping them in zoos and having arboreta where we have trees, all these things have been promoted. Even getting the complete genetic code of various fishes so we can let them pass away and then we'll pull them back. That is science fiction run amok.

The human juggernaut is permanently eroding Earth's ancient biosphere.
