One of the things about genetics that has become clearer as we've done genomes - as we've worked our way through the evolutionary tree, including humans - is that we're probably much more genetic animals than we want to confess we are.

The difference between humans and other mammals is that we know how to accessorize.

Humans have certain properties and characteristics which are intrinsic to them, just as every other organism does. That's human nature.

Genes can't possibly explain all of what makes us what we are.

The human body is essentially something other than an animal organism.

We know virtually all of the genes known to mammals. We do not know all of the combinations.

What exactly is it that humans do that is specifically human? There has to be something. How odd it is for billions of people to be alive, yet not one of them is really quite sure of what makes people people.

We're not inherently anything but human.

A person's basic humanity is not governed by how he or she came into this world, or whether somebody else happens to have the same DNA.

What makes us human depends on what place on our evolutionary path we're talking about. If you go back six million years ago, what makes us human is that we were walking upright. That's all. If you go to 2.6 million years ago, it's the fact that we're designing and making stone tools.
