How did sex evolve? Why are there sexes at all? what are the evolutionary costs and benefits of sex? On this episode, Art and Marty talk with Hanna Kokko, an evolutionary ecologist at the University of Zurich. Hanna studies the evolution of sex and the vast panoply of strategies that organisms use to reproduce. Check out this nice graphical illustration of her work on her website!

What role does one part of the federal government, the National Science Foundation, play in biological research in the US? How will their new funding initiative help us discover Rules of Life? On this episode, Art and Marty talk with two NSF directors, Joanne Tornow. the head of the Biological Sciences directorate, and Arthur “Skip” Lupia, the head of the Social, Behavioral and Economic Science directorate. They talked with them about one of NSF’s Big Ideas. One Idea, called Rules of Life, challenges scientists to study some of the same ‘big’ questions that we’ve addressed on this podcast, including how genotypes become phenotypes. They also asked how an agency dedicated to advancing science operates within an executive branch that has publicly criticized some major scientific conclusions.

How is climate change affecting the distribution of animals? How will these changes in species distribution affect us? Tune in to hear Marty and Art talk with physiological ecologist Jenn Sunday about how climate change is affecting the distribution of life on Earth. Jenn is a professor at McGill University who attempts to answer these questions at a global scale.

Does plasticity always help organisms adapt? What happens if it doesn't? Could it speed up evolution Tune in to hear Art and Marty talk with evolutionary ecologist Cameron Ghalambor about the role of non-adaptive plasticity in evolution. Cam is a professor at Colorado State University who tackles these questions by studying guppies. We interviewed Cam at a bar in Tampa, FL during a conference for the Society for Integrative and Comparative Biology.

Do single genes cause variation in traits or are gene effects more complex than that? How do genes interact with one another, and how do those interactions alter the pace and direction of evolution? Do those interactions constrain or facilitate evolution? Tune in to hear Art and Marty talk with Mihaela Pavlicev about these questions and more! Mihaela is a geneticist at the Cincinnati Children’s Hospital Medical Center, where she studies big new ideas about links between genes and traits.

Will cancer ever become just another chronic but manageable disease? What can a squirrel biologist teach us about treating cancer? In this episode, Marty and Art talk with Joel Brown about how to contain cancer using basic ideas from ecology and evolution. To Joel, cells in tumors are like organisms in ecosystems, and fighting cancer means using what we know about species in nature to tilt the playing field against the worst kinds of cancer cells. He and his team at the Moffit Cancer Research Center in Tampa, Florida, are starting to have some remarkable success treating different kinds of cancer. We interviewed Joel in front of a live audience at Circa 1949 in Tampa, FL—our first live event! We had a great time interacting with the audience and plan to do more events like this in the next few months. If you’d like to host a Big Biology event, please email us at [email protected]!

Why do some animals have weird genitalia? Why is there conflict between males and females when it comes to producing offspring? Tune into this podcast to hear Art and Marty talk with Patty Brennan about how sex in the animal kingdom is not always about love and cooperation; often it's also about conflict. And, this conflict can lead to some pretty crazy genitalia. Patty is an evolutionary biologist at Mount Holyoke College. Her research shows that the birds and the bees aren't so simple for the birds (or, as it turns out, for most other animals). Follow Patty on Twitter: @sexinnature

How has the Tree of Life changed since Darwin? How do genes jump from one species to another? Why do we have viral genes in our DNA? Tune into this podcast to hear Art and Marty talk with David Quammen about his new book “The Tangled Tree: A Radical New History of Life.” In this podcast, they discuss how recent advances in genetics has changed our way of thinking about evolution and the relatedness of plants, animals, and microbes. They also discuss David's methods to his madness as he chooses the topics for each of his books. David is an award winning science writer and journalist. He has published over 15 books and written numerous articles for National Geographic, Rolling Stone, and the New York Times Book Review.

What is life? How did life arise from non-life? What did life look like at its origin? Tune into this podcast to hear Art and Marty talk with Sara Walker, an expert in astrobiology and theoretical physics at Arizona State University. They discuss how life might have arisen on Earth and why biologists and physicists should work together to find a theory of life. Her ideas could help decide what to do about artificial intelligence (SPOILER: The robots will take over, but it’s going to be OK). They might also help us find life on other planets.
