Which do you think is more valuable to humanity?a. Finding ways to tell humans that they have free will despite the incontrovertible fact that their actions are completely dictated by the laws of physics as instantiated in our bodies, brains and environments? That is, engaging in the honored philosophical practice of showing that our notion of "free will" can be compatible with determinism?orb. Telling people, based on our scientific knowledge of physics, neurology, and behavior, that our actions are predetermined rather than dictated by some ghost in our brains, and then sussing out the consequences of that conclusion and applying them to society?Of course my answer is b).

In science's pecking order, evolutionary biology lurks somewhere near the bottom, far closer to phrenology than to physics. For evolutionary biology is a historical science, laden with history's inevitable imponderables. We evolutionary biologists cannot generate a Cretaceous Park to observe exactly what killed the dinosaurs; and, unlike "harder" scientists, we usually cannot resolve issues with a simple experiment, such as adding tube A to tube B and noting the color of the mixture.

For good people to do evil doesn't require only religion, or even any religion, but simply one of it's key elements: belief without evidence-in other words, faith.And that kind of faith is seen not just in religion, but any authoritarian ideology that puts dogma above truth and frowns on dissent.This was precisely the case in the totalitarian regimes of Maoist China and Stalinist Russia, whose excesses are often (and wrongly) blamed on atheism.Faith vs. Fact. p. 220

Now, science cannot completely exclude the possibility of supernatural explanation. It is possible - though very unlikely - that our whole world is controlled by elves.

Every day, hundreds of observations and experiments pour into the hopper of the scientific literature. Many of them don't have much to do with evolution - they're observations about the details of physiology, biochemistry, development, and so on - but many of them do. And every fact that has something to do with evolution confirms its truth. Every fossil that we find, every DNA molecule that we sequence, every organ system that we dissect, supports the idea that species evolved from common ancestors. Despite innumerable possible observations that could prove evolution untrue, we don't have a single one. We don't find mammals in Precambrian rocks, humans in the same layers as dinosaurs, or any other fossils out of evolutionary order. DNA sequencing supports the evolutionary relationships of species originally deduced from the fossil record. And, as natural selection predicts, we find no species with adaptations that only benefit a different species. We do find dead genes and vestigial organs, incomprehensible under the idea of special creation. Despite a million chances to be wrong, evolution always comes up right. That is as close as we can get to a scientific truth.

Many people require more than just evidence before they’ll accept evolution. To these folks,evolution raises such profound questions of purpose, morality, and meaning that they just can’t accept it no matter how much evidence they see. It’s not that we evolved from apes that bothers them so much; it’s [[the emotional consequences of facing that fact.]] And unless we address those concerns, we won’t progress in making evolution a universally acknowledged truth.

Life on earth evolved gradually beginning with one primitive life form – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.

If the entire course of evolution were compressed into a single year, the earliest bacteria would appear at the end of March, but we wouldn't see the first human ancestors until 6 a.m. on December 31st. The golden age of Greece, about 500 BCE, would occur just thirty seconds before midnight.

[W]hen one has a religious experience, what is 'true' is only that one has had that experience, not that its contents convey anything about reality. To determine that, one needs a way to verify the contents of a revelation, and that means science.
