The significance of the guy holding out his arm, dipping at the wrist, is that that's a gesture that magicians use to imitate the cassowary. The cassowary is New Guinea's biggest bird. It's flightless. It's like a small ostrich. Weighs up to 100 pounds. And it has razor-sharp legs that can disembowel a man. The sign of the cassowary, if you hold out your arm like this, that's the cassowary rolling its head and dipping its head when it's ready to charge. So magicians will imitate a cassowary in order to show their power. Because the cassowary's big and powerful. Magicians identify with the cassowary. They intimidate people.

Whatever anybody says, I feel that the hard problem of consciousness is still very hard, and to try and rest your ethical case on proving something that has baffled people for years seems to me to be not good for animals. Much, much better to say let's go for something tangible, something we can measure. Are the animals healthy, do they have what they want? Then if you can show that, then that's a much, much better basis for making your decisions.

There are many other features in the head that help us become exceptional long-distance walkers and runners. I became obsessed with the idea that humans evolved to run long distances, evolved to walk long distances, basically evolved to use our bodies as athletes. These traces are there in our heads along with those brains.
DANIEL LIEBERMAN is Professor of Human Evolutionary Biology at Harvard University. His research combines experimental biology and paleontology to ask why and how the human body looks and functions the way it does. He is especially interested in the origin of bipedal walking, the biology and evolution of endurance running, and the evolution of the human head. He also loves to run.

"One of the fundamental questions here is, is extinction a good thing? Is it "nature's way?" And if it's nature's way, who in the world says anyone should go about changing nature's way? If something was meant to go extinct, then who are we to screw around with it and bring it back? I don't think it's really nature's way. I think that the extinction that we've seen since man is 99.9 percent caused by man."
"I was asked earlier whether the goal is to dissect what Schrödinger had spoken and written, or to present the new summary, and I always like to be forward-looking, so I won't give you a history lesson except for very briefly. I will present our findings on first on reading the genetic code, and then learning to synthesize and write the genetic code, and as many of you know, we synthesized an entire genome, booted it up to create an entirely new synthetic cell where every protein in the cell was based on the synthetic DNA code."

"We can now send biology at the speed of light, and this is one of the implications of our work, which we recorded two years ago making the first synthetic life form. We completely synthesized the genetic code of a cell starting with a digital code in the computer—it's the ultimate interface between computers and biology. The digital code and the genetic code have a lot in common; something Schrodinger pointed out in 1943, saying it could be something as simple as the Morse code."
"This is a hormone that has fascinated me. It's a small molecule that seems to be doing remarkable things. The variation we see in this hormone comes from a number of different sources. One of those sources is genes; many different genes can influence how much testosterone each of us produces, and I just wanted to share with you my fascination with this hormone, because it's helping us take the science of sex differences one step further, to try to understand not whether there are sex differences, but what are the roots of those sex differences? Where are they springing from? And along the way we’re also hoping that this is going to teach us something about those neuro-developmental conditions like autism, like delayed language development, which seem to disproportionately affect boys more than girls, and potentially help us understand the causes of those conditions."
"I'm thinking a lot about species concepts as applied to humans, about the "Out of Africa" model, and also looking back into Africa itself. I think the idea that modern humans originated in Africa is still a sound concept. Behaviorally and physically, we began our story there, but I've come around to thinking that it wasn't a simple origin. Twenty years ago, I would have argued that our species evolved in one place, maybe in East Africa or South Africa. There was a period of time in just one place where a small population of humans became modern, physically and behaviourally. Isolated and perhaps stressed by climate change, this drove a rapid and punctuational origin for our species. Now I don’t think it was that simple, either within or outside of Africa. "
"Why has cooperation, not competition, always been the key to the evolution of complexity?"
