Discussions added each week. These are publication dates here; the original episodes may be older.
- 1:19:07–1:24:07
Church contrasts counselling with gene therapy, then discusses research funding without endorsing the cuts Patel asks him to consider.
- 19:07–24:07
Church discusses his concerns about mirror biology and the difficulty of preventing misuse; the exchange offers no demonstrated safety solution.
- 24:07–29:07
Patel challenges reliance on social solutions; Church discusses monitoring and accountability alongside biological safeguards.
- 1:09:07–1:14:07
Church considers alternative genetic components and argues that evolution need not explore every technologically useful possibility.
- 10:00–15:00
Church compares many-gene traits with large single-gene effects, while cautioning that human enhancement remains difficult.
- 39:07–44:07
Church contrasts early nanotechnology ambitions with biology’s existing capabilities and proposes experimental libraries as a route to new materials.
- 5:00–10:00
Church describes limits of current gene delivery and distinguishes engineered wolf traits from an exact extinct-animal copy.
- 1:14:07–1:19:07
Church advocates genetic counselling, discusses reproductive decisions and cautions against stigmatising people who decline it.
- 54:07–59:07
Church discusses uncertainty about brain engineering and distinguishes generating a brain from copying its particular connections.
- 34:07–39:07
Church compares biological construction with electronics and proposes broader materials capabilities as a future opportunity.
- 59:07–1:04:07
Church imagines combinations of biological growth and engineered materials, while acknowledging gaps in developmental understanding.
- 0:00–5:00
Church discusses uncertain ageing forecasts and possible cellular replacement, including the difficulty of preserving brain function.
- 22:18–27:11
Reich describes methylation research as a possible route to understanding changes in human vocal anatomy.
- 6:59–10:29
Reich stresses uncertainty about population models and where early exchanges between human lineages occurred.
- 1:15:39–1:20:36
Reich discusses selection against Neanderthal variants and distinguishes present DNA proportions from earlier ancestry contributions.
- 1:42:51–1:46:49
Reich discusses South Asian ancestry models and endogamy while separating genetic findings from cultural explanations.
- 1:06:43–1:11:43
Reich discusses uncertain social explanations for sex-biased ancestry and uses Pacific population history as a comparison.
- 51:34–56:21
Reich contrasts directional and stabilising selection, then describes findings from an ongoing ancient-genome study as preliminary.
- 1:50:10–1:53:46
Reich discusses archaeologists’ responses to genetic evidence and the revision of hypotheses about prehistoric language dispersals.
- 42:00–47:00
Reich discusses ancient plague findings and offers a broader hypothesis linking disease to demographic disruption and later migrations.
- 48:17–51:34
Patel and Reich discuss possible demographic and economic effects of epidemics before turning to biological adaptation.
- 1:31:32–1:33:46
Patel asks about research breakthroughs; Reich prioritises much older African DNA for testing human-origin models.
- 59:28–1:04:28
Reich explains how ancient DNA challenged archaeological accounts of migration and discusses ancestry changes without resolving their social mechanisms.
- 1:33:46–1:38:46
Reich describes challenges in recovering ancient evidence and interpreting genomes, contrasting current uncertainty with advances in neuroscience.
