#35 the Evolution of Sleep Part 2EvolutionMedicine add
Why we sleep is not well understood. The study of sleep is one of the last frontiers in human biology. In addition to smoking and bad diet, we can add sleep loss to the list of risk factors for chronic disease. But is modern sleep all that different from that of our ancestors? Joe Alcock, Kate Rusk, Coffee Brown, and Gandhi Yetish explore the mystery of sleep in this Part 2 of our discussion of sleep evolution.
#34 The Evolution of Sleep Part 1EvolutionMedicine add
Why do we sleep? Why did sleep evolve? How much is enough? Do we die if we don’t get enough? Kate Rusk, Joe Alcock, Coffee Brown and special guest Gandhi Yetish discuss these topics in this episode of the EvolutionMedicine podcast. Gandhi has studied the Tsimane, a hunter horticulturalist group in Bolivia. This group, as well as hunter gatherers in Africa - the Hadza and the San - sleep about the same as us: just over 6 hours. What does that result mean for us iPhone gazing city dwellers?
#33 Human Superpowers Part 2EvolutionMedicine add
In this age of Marvel comics, superheroes with superpowers have attained a high degree of cultural fascination. But some superpowers exist in real life, courtesy of natural selection. In part two of this episode, originally livestreamed on Inertia TV, Kate, Joe and Coffee talk about the superpower of the Bajau, a sea nomadic people, to dive longer and deeper than other people. This ability is linked to a bigger spleen, a trait with a heritable signature. Sea Nomads live in the waters of Malaysia, Indonesia and the Philippines. We talk about some other stuff too.
#32 Human Superpowers Part 1EvolutionMedicine add
In this episode, originally livestreamed on Inertia TV, Kate Rusk and Coffee Brown and Joe Alcock discuss whether humans can have actual superpowers. Some human groups have unique abilities to survive underwater, and at the highest altitudes, or deal with temperature extremes. We talk about Tibetans, Andeans, Ethiopian highlanders, and Sea Nomads.

#31 Reproductive ConflictsEvolutionMedicine add
Kate Rusk and Joe Alcock discuss the evolutionary reasons why pregnancy is so dangerous, both for fetus and for mother. Genetic conflicts of interest between paternal and maternal genes may give rise to gestational diabetes and preeclampsia. Evolutioanry theorist David Haig came up with these ideas, inspired by Robert Trivers "parent offspring conflict." This hypothesis of genetic conflicts in pregnancy has held up over the years, yet these concepts still are not taught in medical school, remarkably. This episode was originally livestreamed on Inertia TV with Kate Rusk. Javier is a prop skeleton, by the way.
#30 Resistance EvolutionEvolutionMedicine add
Kate Rusk and Joe Alcock recorded this for Inertia TV in March 2018. We talk about the reasons for resistance evolution, alternatives to antibiotics, and which drugs predispose to Clostridium difficile. What to do if no antibiotics work? Fecal transplants of course.
#29 Evolution and Emergency MedicineEvolutionMedicine add
Does evolution matter in the emergency department? Joe Alcock describes why it does. This episode was recorded for Joe Tomkins Darwinian Revolution class in University of Western Australia on April 5, 2018 at the Inertia TV studio, thanks to Kate Rusk.

#28 Depression - Feature or Bug? Part 2EvolutionMedicine add
In part two Joe Alcock, Coffee Brown, Paul Watson talk about how evolution might guide the treatment of patients with mood disorders. We talk about the evolution of sickness behavior, the utility of antidepressant drugs, and the role of the microbiome in depression and anxiety.
#27 Depression - Feature or a Bug? Part 1EvolutionMedicine add
Coffee Brown and Joe Alcock are joined by evolutionary biologist and theorist Paul Watson to discuss whether depression is a feature or a bug. Paul Watson developed the social navigation hypothesis along with Ed Hagen, Paul Andrews, and others to explain depression as a unconscious way to break social contracts and make new ones. Watson now calls this the "niche change" hypothesis. This is part one of two.
#24 Food Evolution with Kate Rusk Part 1EvolutionMedicine add
Kate Rusk and Joe Alcock discuss the evolutionary biology of food. This episode is part one, originally recorded by Inertia TV, a science channel on Twitch.
# 23 The Placebo Effect Part 2EvolutionMedicine add
This is part two of a recording that originally appeared on Inertia TV https://www.twitch.tv/inertiatv_
Kate Rusk, Coffee Brown and I discuss why back surgery is the ultimate placebo, what makes our brains work the way they do, and how doctors can harness the placebo effect in our practice. We riff on martial arts, religion, and of course, evolution too
# 22 The Placebo Effect Part 1EvolutionMedicine add
Kate Rusk of Inertia TV, along with Joe Alcock and Coffee Brown of the EvolutionMedicine podcast do a deep dive on the placebo effect. Why did this capacity evolve in the first place? How can we harness the placebo effect? This is part one. originally recorded and live streamed on Twitch on March 20, 2018. Also check out part 2.

#21 Intro to EvMed on Inertia TVEvolutionMedicine add
This year, evolutionary anthropologist Kate Rusk began a streaming video science channel, called Inertia TV, that streams great science programming, including this program: Evolutionary Medicine with Joe Alcock MD. This episode was an introductory conversation on EvoMed between me, Joe Alcock, and Kate Rusk, recorded and live streamed in February 2018. Kate, Coffee Brown and I live streamed several episodes since then. The audio versions of all episodes will be released periodically over the next few weeks (video excerpts too).

#20 Too Much Oxygen?EvolutionMedicine add
Coffee Brown and Joe Alcock discuss the perils and pitfalls of too much oxygen. We discuss the recent IOTA study - a metaanalysis done by Paul Young's team and the upcoming ICUROX trial. This evidence is going to change how we practice medicine. It also has insights for evolutionary biology - our bodies can be self destructive, as in heart attacks and strokes, but healing processes may rely on normal to low normal oxygen levels. Too much oxygen may indeed be a bad thing
#19 Cognitive BiasesEvolutionMedicine add
Joe Alcock and Coffee Brown have a discussion about evolution, medical decision making, and cognitive biases. We focus on a few major cognitive biases - achor bias, attribution bias, immediacy bias, halo effect, among others. We consider how our cognitive and sensory apparatus evolved in ways that can lead us to make mistakes. We explore the idea that the smoke detector principle can affect doctors' behavior and make ER docs more risk averse. How can we make better decisions with these cognitive pitfalls?
#18 Lessons from the ADRENAL trialEvolutionMedicine add
This week Joe Alcock and Coffee Brown get into the weeds of the ADRENAL trial - a huge study designed to answer the question - does giving steroids to patients with sepsis help or hurt? I say it hurts, Coffee is not so sure. We talk about why anti-inflammatory treatments have always failed in patients with septic shock. The lesson, it turns out, is an evolutionary one.
#17 No Love for evolution in medical schoolEvolutionMedicine add
Joe Alcock and Coffee Brown discuss evolution, creationism, race and plenty of other hot topics while trying to explain why evolution gets no love in medical school
# 16 Hypress Trial And JapanEvolutionMedicine add
This is a previously episode first recorded in early 2017. It is timely, though, because a major trial on the effects of corticosteroids - the ADRENAL trial - will soon be made public. In this podcast I make the case that steroids are no bueno for patients with sepsis. I also discuss trauma in Japan, New Zealand, and South Africa. Enjoy
