Into the Impossible With Brian Keating The Next Phase of Human Evolution (ft. Bret Weinstein)
Dec 9, 2025
Join evolutionary biologist Bret Weinstein, co-host of the Dark Horse Podcast, as he explores the future of human evolution. He delves into the complexities of senescence and how life cycle traits impact lifespan. Bret critiques the hype around de-extinction, emphasizing the reality of hybrid creatures. He also discusses the risks posed by AI, highlighting societal fragility and the need for sober realism. Learn about the role of culture in adaptation and the importance of preparing for the unforeseen challenges of modernity!

Episode notes
Biology Needs Relaxed Falsification
- Biology uses the scientific method but its high complexity demands statistical relaxation of strict falsification rules.
- Bret Weinstein argues biology's noise requires many examples to validate hypotheses, unlike physics or chemistry.
Why Aging Is An Evolutionary Outcome
- Senescence evolves because material heredity pressures genome compression and pleiotropy, causing genes to have beneficial early effects and harmful late effects.
- Weinstein explains replacing worn somas with fresh versions can be evolutionarily optimal once late-life degradation is severe.
Germline Structure Shapes Aging
- Presence or absence of a sequestered germline shapes type of senescence; plants age differently because their germline isn't isolated.
- Trees show reduced fruiting with age rather than the mammalian soma/germline pattern Weinstein describes.
