“If the history-deniers who doubt the fact of evolution are ignorant of biology, those who think the world began less than ten thousand years ago are worst than ignorant, they are the deluded to the point of perversity.”

The idea of a divine creator belittles the elegant reality of the universe.

We admit that we are like apes, but we seldom realize that we are apes.

Let us try to teach generosity and altruism, because we are born selfish. Let us understand what our own selfish genes are up to, because we may then at least have the chance to upset their designs, something that no other species has ever aspired to do.

We are all atheists about most of the gods that humanity has ever believed in. Some of us just go one god further.

The chicken is only an egg’s way for making another egg.

Why, I can’t help wondering, is God thought to need such ferocious defence? One might have supposed him amply capable of looking after himself.

Religious fanatics want people to switch off their own minds, ignore the evidence, and blindly follow a holy book based upon private revelation.

Evolution could so easily be disproved if just a single fossil turned up in the wrong date order. Evolution has passed this test with flying colours.

Religious faith, is a state of mind, that leads people to believe in something, it doesn’t matter what, without a whisper of doubt, or a whiff of evidence, and believe so strongly in some cases, that they are prepare to kill and die for it, without the need for further justification.

Religion teaches you to be satisfied with nonanswers. It’s a sort of crime against childhood.

I am against religion because it teaches us to be satisfied with not understanding the world.

When one person suffers from a delusion, it is called insanity. When many people suffer from a delusion it is called Religion.

We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes. This is a truth which still fills me with astonishment.

Downloading a Tamagotchi egg onto my phone is possibly the loudest my biological clock has ever ticked.

We are living in times when technology, biology and chemistry have created the possibility of killing in large numbers.

After all, our families–our ancestors–are our identities. Biology is destiny.

Not biology, but ignorance of ourselves, has been the key to our powerlessness

The origins of violence against women by men are not biological. If that were the case, it would exist in every culture. And it doesn’t exist in every culture.

You have to understand your own personal DNA. Don’t do things because I do them or Steve Jobs or Mark Cuban tried it. You need to know your personal brand and stay true to it.

Biologists must constantly keep in mind that what they see was not designed, but rather evolved.

Your biography becomes your biology. This biography includes the totality of your choices, the things you feed your body – you thoughts, your actions, your food – the thing you feed your life.
