In their own words

This Week in Evolution is a podcast on the biology of what makes us tick. Hosts Nels Elde and Vincent Racaniello take you through the new evolution that has been revolutionized by the field of genomics and molecular biology.

As heard by us

Based on 5 episodes we listened to · September 2026

Detailed conversations connect molecular change, host biology and population patterns without hiding the uncertainty inside evolutionary evidence.

Vincent Racaniello and Nels Elde treat evolution as a process to be examined at several scales. Their coronavirus discussions move from mutations within one patient to transmission between hosts and competition across populations, with careful attention to what the available…

On racism, not race with Joe GravesFeb 3, 2022

Joe Graves explains why biological race concepts are arbitrary and how they became tied to white supremacy.

Joe Graves frames race through the history of biological classification, explaining why human racial categories are arbitrary and how those labels became bound up with white supremacy, chattel slavery, and Jim Crow.

With a little help from your hostsDec 28, 2021

A careful look at how viral variation inside one patient can, on rare occasions, matter to the wider population.

Viral evolution becomes less a march than a matter of timing, chance, and selective pressure as Vincent Racaniello and Nels L.D. revisit Alpha, Delta, and Omicron.

Echoes of evolution both shallow and deepOct 26, 2021

A mailbag discussion connects an ancient CCR5 signal with HIV's changing routes into cells.

A mailbag question opens into evolution on two clocks: an old genetic signal around CCR5, and HIV's ongoing knack for finding ways into cells.

Faster than a speeding coronavirusSep 27, 2021

A focused look at coronavirus mutations as they emerge within a person and recur across variants.

Coronavirus evolution gets a clear, close treatment as the episode moves from the spike's shape to the molecular logic of its bond with human ACE2.

On Life's Edge with Carl ZimmerAug 3, 2021

Carl Zimmer follows the origins-of-life question from Darwin's era toward algorithms that could read new polymers.

Carl Zimmer's conversation with Nels Elde treats the origins of life as both an old intellectual pursuit and a question now edging toward a computational future.
