EAT ME BEFORE I EAT YOU! A NEW FOE FOR BAD BUGS

[3.17.10]

"Now we are starting to work with organisms that are more likely to appear in a hospital, like staph and influenza, and we have our sights on Clostridia difficile, Pneumococcus aeruginosa, Acetinobacter baumanii and an alarming number of other bacteria that are resistant to antibiotics. We are also working on influenza, which has a convenient little feature called M2e."


 

TOXO

[12.2.09]

"The parasite my lab is beginning to focus on is one in the world of mammals, where parasites are changing mammalian behavior. It's got to do with this parasite, this protozoan called Toxoplasma. If you're ever pregnant, if you're ever around anyone who's pregnant, you know you immediately get skittish about cat feces, cat bedding, cat everything, because it could carry Toxo. And you do not want to get Toxoplasma into a fetal nervous system. It's a disaster."

Why Sex Differences Matter: The Darwinian Perspective

[9.30.09]

"If we want to change the world, we need first to understand it. And when it comes to understanding human nature — male and female — Darwinian science is indispensable."


 

Darwin and the Evolution of Reasons

[9.30.09]

"Some people think today that it is impossible for a mindless process to produce evolution. ... It isn't. ...There may be an intelligent God hidden in the evolution process, but if so, he might as well be asleep, since there is no work for him to do!"

Beauty's Child: Sexual Selection, Nature Worship and the Love of God

[9.30.09]

"...I want to engage you in a discussion of the deep history of beauty. By deep I mean as seen from an evolutionary perspective. I am an "evolutionary psychologist".  I believe that to understand and fully appreciate human mental traits, we need to know why they are there — which is to say what biological function they are serving.  Evolutionary psychology has been making pretty good progress. But, as we say, "there are still some  elephants in the living room" — big issues that no one wants to talk about. And human beings worship of the beautiful remains  one of the biggest."


 

Darwin's Intellectual Legacy to the 21st Century

Why Chile?
[9.7.09]

From the Program Notes: "Our intention is to illuminate and discuss how Darwinian thought influenced the disciplines that focus on the study the individuals (biology, neuroscience, psychology); the individual within their social interactions (anthropology, sociology, economy, political science); and how these concepts pertain, in general, to a moral philosophy.

We wish to explore how, from Darwinian thought, there emerges a vision of what it is to be a human being. And that this vision is fundamental and coherent with the entire body of accumulated scientific knowledge. With reverence for the details of their application, it is the impact of Darwin's ideas that is the reason we are celebrating Darwin's anniversary."


 

AMAZING BABIES

[8.11.09]

"We've known for a long time that human children are the best learning machines in the universe. But it has always been like the mystery of the humming birds. We know that they fly, but we don't know how they can possibly do it. We could say that babies learn, but we didn't know how."

THE EVOLUTION OF COOKING

[8.8.09]

"One of the great thrusts of behavioral biology for the last three or four decades has been that if you change the conditions that an animal is in, then you change the kind of behavior that is elicited. What the genetic control of behavior means is not that instincts inevitably pop out regardless of circumstances; instead, it is that we are created with a series of emotions that are appropriate for a range of circumstances. The particular set of emotions that pop out will vary within species, but they will also vary with context, and once you know them better, then you can arrange the context.... It's much better to anticipate these things, recognize the problem, and design in advance to protect."

MAPPING THE NEANDERTHAL GENOME

[7.4.09]

"When I started out in '84/'85, intent on studying the genomes of ancient civilizations, I was, as is often the case in this kind of situation, driven by delusions of grandeur. I thought that I would be able to easily study the ancient genomes. I dreamt of addressing questions in Egyptology. For example, how do historico-political events that we read about impact the population? When Alexander the Great comes to Egypt, what is the influence on the population? Is it just a political change? The Arab Conquest: does that mean that a large part of the population is replaced? Or is it mainly a cultural change? There's no way we can answer this question from historical records. But my dream was to address questions like this. Then, after some initial success, I realized the real limitations on what I wanted to do."
