The fundamentalists, by 'knowing' the answers before they start (examining evolution), and then forcing nature into the straitjacket of their discredited preconceptions, lie outside the domain of science-or of any honest intellectual inquiry.

Evolution is a process of constant branching and expansion.

We who revel in nature's diversity and feel instructed by every animal tend to brand Homo sapiens as the greatest catastrophe since the Cretaceous extinction.

Why should our nastiness be the baggage of an apish past and our kindness uniquely human? Why should we not seek continuity with other animals for our 'noble' traits as well?

The proof of evolution lies in those adaptations that arise from improbable foundations.

Objectivity cannot be equated with mental blankness; rather, objectivity resides in recognizing your preferences and then subjecting them to especially harsh scrutiny — and also in a willingness to revise or abandon your theories when the tests fail (as they usually do).
