Putting our close genetic relationship to chimpanzees into perspective

Genomics Professor Katherine Pollard explored the genetic basis for being human in a video presentation titled "What Makes Us Human. Here a rather dramatic announcement from her talk:

Mouse and rat actually have a common ancestor longer ago than human and chimp, and some people will be surprised by that. They will say, "We are so much more different than a chimp . . . mouse and rat must be pretty similar." Actually mouse and rat on average are much more different from each other than we are from a chimp, and that's sort of a humbling fact to keep in mind.
We're not exactly like chimpanzees, of course, but there are quite a few overlaps (as well as differences), which Pollard explores beginning at the 4-minute mark. Surprisingly, young chimpanzees have a better competency in counting and numbers than young humans. At the 11-minute mark, you can see that the human genome is 95% similar to that of a chimp (or 99%, depending on how you define similarity), and that it is 28% similar (or 89%, depending on definition of similarity) to the genome of a mouse.

Richard Dawkins discusses the Greatest Show on Earth

In this Fora.TV video of a talk he gave at U.C. Berkeley, Richard Dawkins discusses his most recent book, The Greatest Show on Earth. In the early minutes of the talk, he explains why fossils are "icing on the cake" and he illustrates the "problem" with gaps by use of a humorous story. At minute 43:00, Dawkins explore the anthropic principle. At minute 49:00, Dawkins comments on the use of the word "why," as part of his comment on the question "Why are we here?" He explains: It's no more deserving of an answer than the question: "Why are unicorns hollow?" Dawkins also comments on the mechanism the creates conscious pain at minute 52:00, before declaring his own attempt to explain it to be incoherent. On the likelihood of a random mutation improving an organism, Dawkins points out that it is highly unlikely: "There are many more ways of being dead than alive." This video offers lots more engaging back and forth in the comments portion, following the main presentation. [More . . . ]

Capitalism under the microscope

Annie Leonard has passionately researched and written a book she titles: The Story of Stuff: How Our Obsession with the Stuff Is Trashing the Planet, Our Communities, and Our Health-and a Vision for Change (2010). I haven't yet finished her book, although I'd like to post on one point she strongly makes early on, a point that is the elephant in the room regarding most discussions of the American way of life. It is a topic not far from the hearts of the many free market fundamentalists out there. The topic is whether it's time to put capitalism under the microscope. Here's what Leonard has to say:

[There is no doubt we will reach the planet's carrying capacity; we're heading in that direction now.... a big part of the problem we face today is that our dominant economic system values growth as a goal unto itself, above all else. That's why we use the gross to metric product, or GDP as a standard measure of success.... All right. Are you ready? I'm going to say it: this critique of economic growth is a critique of many aspects of capitalism as it functions in the world today. There. I said the word: "capitalism." It's the Economic-System-That-Must-Not-Be-Named. When writing the film script of The Story of Stuff, my intent was to describe what I saw in my years on the trail of trash, visiting factories and dumps and learning about how things are made, use, and thrown away around the world. I certainly didn't sit down and figure out how to explain the flaws of capitalism. It was trash, not economics, that was originally on my mind. So at first it took me by surprise that some commentators called the film "an ecological critique of capitalism" or "anti-capitalist."... it turns out that a hard look at how we make and use and throwaway Stuff reveals some pretty deep problems caused by core functions of a specific economic system called capitalism. There's no way around it: capitalism, as it currently functions, is just not sustainable.... Yet, in the United States, were still hesitant to broach this unmentionable subject, fearful of being labeled unpatriotic, unrealistic, or insane. Elsewhere in the world, there's a widespread recognition that some aspects of capitalism aren't working well for the majority of the world's people or for the planet; people talk about it openly.... Can we put capitalism on the table and talk about it with the same intellectual rigor that we welcome for other topics? Can we examine the failures of capitalism without falling into generations-old stereotypes and without being accused of being un-American? Refusing to talk about it doesn't make the problems disappear. I believe the best way to honor our country is to point out when it's going astray, instead of sitting here silently as many economic, environmental, and social indices worsen. Now would be a good time to start looking at what we could do differently, and what we could do better.... The belief that infinite economic growth is the best strategy for making a better world has become like a secular religion in which all our politicians, economists, and media participate; it is seldom debated, since everyone is supposed to just accept it as true. Why are so few people willing to challenge, or even critically discuss, an economic model that so clearly isn't serving the planet and the majority of its people. I think one reason is that the economic model is nearly invisible to us. ... [W]e tend to forget that were viewing the world through the paradigm, like it's a pair of contact lenses.... before we can change a paradigm, we need to identify it as a paradigm rather than assume it is truth.

Compelling gossip

I was on a two-hour bus ride today, surrounded by people chattering loudly on their cell phones. From the large man with the goatee (in front of me, to my left), I leaned that he had bacon and eggs this morning at a little restaurant and that it was good. It took him five minutes to describe his meal to the person with whom he was conversing (I do wonder whether that person was really listening to the entire thing). The woman in front of me was getting angry at the person to whom she was talking--she insisted that there was a closer Wal-Mart, and that that person ought to turn her car back immediately and go there, not to the Wal-Mart down the road. A man behind me was making a wide variety of calls, reassuring people that he would be visiting someday, and apparently trading much chit-chat. The woman behind me was discussing various movies with her conversant. Again, there were lots of details, and it seemed as though each of these conversations ended because the people got tired of talking, not because they traded any significant information. All of this chattering was irritating to me, because I have a difficult time filtering out one-sided conversations. Every time the person near me stops talking, an internal warning kicks in and I automatically replay my buffer (as best I can) in order to jump in and respond. It's all automated, and it turns out, time after time, that they are not talking with me at all. My little sub-routine, which works rather well in many situations where someone has paused for the purpose to allow me to respond, is merely an annoyance in these situations. Now multiply this gossipy chatter by hundreds of millions, all across America, and you have an enormous amount of time and energy dedicated to gossip. Whenever you see so much energy going into an activity, red flags should go up: it is likely that such a ubiquitous activity is serving some important biological function. But what could possibly be important about gossiping? Based upon much study, Robin Dunbar has proposed the answer that gossip is verbal grooming. I described his position in some detail here. His bottom line is that even though the content of the gossip seems relatively unimportant, the exchange is critically important. Engaging in gossip is social sonar. It is our way of determining the identities of our allies and foes, not simply by determining who is willing to gossip with us, but through many subtle clues dropped in the course of the gossip. We learn the identities of the people who talk about us and our friends, and bits and pieces about their attitudes toward us. We learn who has resources, social and material, and their willingness to share these resources, and with whom. Gossip is a powerful use of language, but it is often not focused on the truth-content of the words used. In modern times, gossip is likely to be seen as a Gouldian spandrel. But just maybe, as Dunbar suggests, gossip is truly verbal grooming and thus arguably the original impetus for the development of all human languages. As I see it, gossip but one of several non-prototypical uses of language. I suspect that we see another such use in most religions, where language can be critically important, even though ambiguous, untrue or even oxymoronic.
