BMC Biol. It’s essentially a history book describing the birth of molecular biology. It’s a book I’ve returned to several times because I think you can appreciate it at different stages of life. You might think, looking at a forest or a tide pool, that all the creatures in it are equal. I have to believe, I either can be a complete pessimist which I wouldn’t have taken the job I have if I was or I have to believe there’s one way out and one way out is education and for people to be motivated to do things. – 35:54 My question is more specific to your paper on the wingless morphogen and you concluded that the null spot in Gypsophila caricifolia had something to do with a cooption of the wingless expression due to something involved in development of Campaniform sensilla and I was wondering have you performed more research to figure out exactly how that came to be? Why did you choose this? I sort of imagined that I might be, I don’t know a zookeeper or something like this. Kim, J., K. Johnson, S. Carroll, and A. Laughon (1997) MAD binds to DNA and directly mediates the long-range activation of the vestigial wing patterning gene by the DPP morphogen. That immediately directed us away from this idea that you needed new genes to make new kinds of bodies and towards asking well, the same genes are there but they’re being used in different ways, how does gene regulation change? Finally, on intermediate scales, I am interested in connecting the entropic arrow of time to our everyday notions of causality, memory, and free will. It also leads to acid rain, acid rain, very bad for soils, very bad for shallow water and freshwater. So it seemed like if we knew how to make a model arthropod like that, big questions about evolution of bodies would be opened. The forest, we need to maintain large tracts of forest, water quality is really important, you all know the story, we can’t keep pumping carbon dioxide at the rate we are.

In terms of gems, well I told you about the snake venom project and this is, I’m really psyched about this and it’s a complete throwback sort of thing. So it’ll cost you 32 minutes of your life if you want to watch the film, but one of the things I started here is a film unit at Hughes, this is where I’m talking to you from is Howard Hughes and Chevy Chase and I’m right now working with a film producer to tell the story I just told you which is comparing two extinctions, the KT and the Permian and comparing it to the environmental phenomenon we see going on today. Lab ph. He went island hopping across that archipelago – visiting islands like Borneo, Sumatra, Lombok, Bali. He had fierce critics and a few supporters. What happens if we accidentally or intentionally remove them? But I’m also optimistic because, although nothing happens as fast as we’d like it to, we know lots more now than 30 or 40 years ago. Some of my favorite topics have included dark matter and dark energy, the arrow of time, inflation, extra dimensions, modified gravity, and possible violations of fundamental symmetries. They pose the following question to students on the first day of their introductory classes: ‘What is the most... Pizza to the Polls is making democracy delicious by delivering free food for all to polling places with long lines. So I worked on the building of the fruit-fly body plan in the 1980s and in to the early 1990s, various aspects of how do you make the right number of segments, how do you specify the identity of those segments, how do you make certain body parts like wings and all that. I grew up on the shores of Lake Erie, I never put a finger or a toe in Lake Erie as a kid. Read Now imagine if you tweak that element a little bit it’s not that hard to add a seventh input, add an additional input or for the combination of inputs to change in some way that now that might be active in even more cells or in a smaller population of cells. Quammen describes how pioneering biologists and ecologists are using islands as laboratories to try to figure out fundamental questions such as how many species can live in a particular place. So you may know that the worst mass extinction was at the end of the Permian, about 252 million years ago.

My research goal is to obtain a better understanding of how Nature works, on various levels and in a number of different contexts. And if you’ve read the, and I know you did read this review I wrote for Cell in 2008, the big expectation that had been around for 25 years or more was that for new things to happen in evolution you needed new genes.
