No single discovery from any of these fields denotes proof of evolution, but together they reveal that life evolved in a certain sequence by a particular process.

Play hard, work hard, love hard. . . .The bottom line for me is to live life to the fullest in the here-and-now instead of a hoped-for hereafter, and make every day count in some meaningful way and do something-no matter how small it is-to make the world a better place.

Mammals are sentient beings that want to live and are afraid to die. Evolution vouchsafed us all with an instinct to survive, reproduce and flourish.

My thesis is that morality exists outside the human mind in the sense of being not just a trait of individual humans, but a human trait; that is, a human universal.

We know evolution happened not because of transitional fossils such as A. natans but because of the convergence of evidence from such diverse fields as geology, paleontology, biogeography, comparative anatomy and physiology, molecular biology, genetics, and many more.

To be a fully functioning moral agent, one cannot passively accept moral principles handed down by fiat. Moral principles require moral reasoning.

When alien abductees recount to me their stories, I do not deny that they had a real experience.
