I say to the grown-ups, 'If you want to deny evolution and live in your world that's completely inconsistent with everything we've observed in the universe that's fine. But don't make your kids do it.'

I don't perceive an anti-religious agenda, especially with regard to Christians and Christianity.

But as the cerebellum degrades with age, so does the quality of memories. The memories are there, but they're not as good.

I'll admit that the discovery of evolution is humbling, but it is also empowering. It transforms our relationship to the life around us. Instead of being outsiders watching the natural world go by, we are insiders. We are part of the process; we are the exquisite result of billions of years of natural research and development.

We need them. We need scientifically literate voters and taxpayers for the future.

Apparently there is redundancy in memory: You store the same memory in different parts of your brain for accessing at different speeds. That speed would depend on the frequency of use and the importance of the knowledge.

I try to speak plainly and be sympathetic to the idea of religions where people gather in community. They get a sense of people looking out for each other. My claim is that we have a tendency to look out for each other whether or not there is a religion involved.
