This week on Big Biology we're sharing an episode from The Naked Scientists Podcast about how humans lost their tails.
Humans, chimpanzees, gorillas and orangutans do not have tails. It sets us apart from other primates, but suggests that our shared evolutionary ancestors had them. So why did we lose them, and how? Speaking with Chris Smith, from The Naked Scientists Podcast, NYU Grossman School of Medicine's Itai Yanai explains that the way this study began was literally a pain in the "tail" for one of his colleagues...

At what levels does causation happen in biology? Are metaphors useful for understanding biology?
In this episode, we talk with Phil Ball, a science writer who was also an editor for the journal Nature for over 20 years. Phil has written over 25 books, but our conversation focuses on his most recent: “How Life Works: A User’s Guide to the New Biology.” In the book, Phil covers a wide-range of topics from cells to proteins to biological agency, and makes the argument that traditional ideas and simplified metaphors in biology often don’t hold up. We talk with Phil about the concept of the selfish ..read more

How should biologists deal with the massive amounts of population genetic data that are now routinely available? Will AIs make biologists obsolete?
In this episode, we talk with Andy Kern, an Associate Professor of Biology at the University of Oregon. Andy has spent much of his career applying machine learning methods in population genetics. We talk with him about the fundamental questions that population genetics aims to answer and about older theoretical and empirical approaches We then turn to the promise of machine learning methods, which are increasingly being used to estimate popul ..read more

How should we study complex biological networks? How do cells keep time and stay in sync? What does it mean for a network to be resilient?
In this episode, we talk with Rosemary Braun, Associate Professor at Northwestern University in the Department of Molecular Biosciences and a member of the NSF-Simons Center for Quantitative Biology. Rosemary is broadly interested in learning whether “more is different” when it comes to complex molecular networks operating across different temporal and spatial scales. We talk with her about systems approaches to uncovering the “Rules of Life” and about circ ..read more

How do biologists strike a productive balance between descriptive natural history and manipulative experiments in the lab or field? Should we bring back species to areas where they’ve gone extinct and what values do we use to make these decisions? What is wildness and how do we cultivate it?
On this episode, we talk with Harry Greene, a herpetologist and adjunct professor of Integrative Biology at the University of Texas at Austin, whose distinguished career has spanned decades. Harry is an E.O. Wilson Award recipient and also received the PEN Literary award for his book, Snakes: The Evolution ..read more

What is an agent, and does an organism have to be conscious to be one? How does organismal agency affect evolution?
In this episode, we talk with Samir Okasha, a Professor of Philosophy of Science at the University of Bristol. Samir studies fundamental philosophical questions in evolutionary biology, most notably how selection acts on various levels of biological organization. Our discussion focuses on his book “Agents and Goals in Evolution,” in which he unpacks various definitions of agency and outlines their evolutionary implications. We talk about whether genes and groups of individuals ca ..read more

If the tape of life were replayed, how recognizable would today’s species and ecosystems be? How and why does power increase over evolutionary time? How have humans unleashed so much power, and what are the consequences of that power for life on Earth?
In this episode, we talk with Geerat Vermeij, a paleoecologist and evolutionary biologist in the Department of Earth and Planetary Sciences at UC Davis. He is a member of the National Academy of Sciences, and has published over 200 papers and five books. Our conversation focuses on his most recent book: “The Evolution of Power: A New Under ..read more

How are cephalopods like us, but also completely alien? How can they become so intelligent when they have such short lives? How do they coordinate a distributed set of brains?
In this episode, we talk with Danna Staaf, a science communicator and marine biologist with a lifelong love of cephalopods. Danna earned a PhD from Stanford University studying baby squid, and she has written several cephalopod-themed books. Our conversation focuses on Danna’s most recent, The Lives of Octopuses and Their Relatives: A Natural History of Cephalopods, a beautiful exploration of the diversity of these wacky ..read more

Does biological plasticity have a cost? Are there evolutionary consequences of plasticity and of organisms acting on their environments?
In this episode, we talk with Sonia Sultan, the Alan M. Dachs Professor of Science in the Department of Biology at Wesleyan University. Sonia has spent her career studying the interplay between organisms and their environment. Specifically, she studies how environmental conditions influence the development of organisms, and when and how these developmental trajectories can include niche construction. Sonia refers to this complexity as “entanglement,” genes an ..read more

How do small, founding populations establish and thrive in new places? What is biocontrol, and how is it carried out responsibly?
In this episode, we talk with Ruth Hufbauer, a Professor of Applied Evolutionary Ecology at Colorado State University about the ways that organisms successfully establish new populations in new places. Ruth uses lab experiments onTribolium flour beetles to understand how evolution facilitates or impedes the founding of populations. In our conversation with Ruth, we discuss range expansions, species invasions, and biocontrol among other topics. Biocontrol is of ..read more
