Herman Pontzer and colleagues published a landmark study of energy expenditure in people from a very physically active hunter-gatherer group, the Hadza of Tanzania. These important findings have been central to how I think about diet and obesity. Here is what they found: Hadza hunter gatherers spend about the same […]
Interferon is an innate immune molecule with an important antiviral function that provides a first line of defense against infection. Interferons are found across the tree of life, existing in all tetrapods and most fishes. It is thought that interferon evolved first in jawed fishes, about 400 million years ago. […]
I spent some time this week looking back at our year of pandemic and considering the question of how evolutionary medicine can help guide treatment in the emergency department. My first reaction to this question was: “of course evolutionary medicine is useful during every step of the patient encounter.” It […]
I cannot think of a time in my life when newspaper headlines overlapped quite as much with the scientific enterprise of evolutionary medicine. Here is an example, from Bloomberg: “British doctors who spent 102 days treating a cancer survivor for Covid-19 documented how the virus mutated after the man was […]
I listened recently to a podcast conversation between physicians David Katz and Zubin Damania on the ZDoggMD podcast and a few things caught my attention. First, and relevant to this blog, Katz referred to the evolutionary biology of disease a few times during the podcast. Here is Katz on obesity: […]

This wildly multidisciplinary conference uses a zombie lens to explore topics in medicine, social science, art and popular culture. I am Dr. Zed this week, broadcasting the apocalypse every day on a variety of streaming platforms. Check […]
Athena Aktipis and I wrote a piece about this in TheConversation.com: Here is an excerpt: Viruses walk a fine line between severity and transmissibility. If they are too virulent, they kill or incapacitate their hosts; this limits their ability to infect new hosts. Conversely, viruses that cause little harm may […]
I often feel that I am writing this blog for myself, but I have a platform here. The evolution medicine blog and podcast has a modest number of subscribers. With the recent murder of George Floyd, I am moved to speak. I have been inspired by the peaceful protests that […]
Researchers and opinion leaders cannot seem to make up their minds about what kills us in a variety of serious viral illnesses. Do we die because of too much, or too little, immune activation? Consider this about Ebola virus from an 2014 NPR feature: “But when you look at the […]
The billionaire hedge fund manager Ricky Sandler says we should disregard public health professionals and encourage people to get infected with COVID-19 so that the population can have “so called” herd immunity. He and others argue we should throw caution – and our face masks – to the wind and […]
