Discussions added each week. These are publication dates here; the original episodes may be older.
- 3:05:56–3:09:33
Lane distinguishes environmental feedback from planetary natural selection, then the speakers introduce analogies between cells and cities.
- 28:53–32:29
Lane describes planets as possible energy systems and explains why he expects water and carbon chemistry to matter elsewhere.
- 1:24:59–1:29:05
The speakers consider perception and reality, with Lane emphasising sensory limitations and learning through interacting signals.
- 2:35:41–2:38:39
Lane discusses long-term environmental conditions and uses geological crises to consider feedbacks and changes in habitability.
- 0:00–4:07
Lane introduces competing origin-of-life ideas and describes hydrothermal vents as a possible setting for early chemical energy conversion.
- 1:41:33–1:46:03
Lane connects bodily needs and electrical membrane properties to speculative evolutionary explanations of feeling, while acknowledging uncertainty.
- 12:25–16:47
Lane considers differences in cellular machinery and argues that delivering organic ingredients from space would not explain their organisation into life.
- 2:22:00–2:26:02
Lane explains why he expects simple life to be more common than complex life and presents his evolutionary bottleneck argument.
- 1:46:03–1:50:12
The speakers compare machine learning, infant development and relationships with animals while examining how people attribute subjective experience.
- 46:00–49:58
Lane connects large genomes to developmental possibilities and discusses models for the evolution of sexual reproduction.
- 2:38:39–2:43:27
Lane describes isotope evidence and a proposed connection between sulfate, oxidation and changes in ancient oceans.
- 2:13:06–2:17:21
Lane discusses mitochondrial interactions in fruit flies, then the speakers examine intuition, hypotheses and creative connections in science.
- 2:47:58–2:52:24
The speakers distinguish intelligence from consciousness and consider what kinds of explanations might address subjective experience.
- 2:31:09–2:35:41
Lane discusses how extraterrestrial chemistry might inform common-ancestry questions, then considers icy ocean worlds and the history of photosynthesis.
- 1:11:12–1:15:58
Lane considers contingent explanations for human evolution, including social interaction and the transmission of knowledge.
- 59:17–1:02:15
The speakers consider historical contingency and optimisation, with Lane questioning how assumptions affect claims about the genetic code.
- 32:29–37:19
Lane discusses possible chemical constraints on the genetic code, then considers the difficulty and ecological importance of oxygen-producing photosynthesis.
- 3:31:22–3:35:36
The speakers discuss fulfilment and recognition, then consider what makes Earth remarkable as a place supporting complex life.
- 1:33:56–1:37:33
Lane contrasts proposed accounts of consciousness and argues that subjective feelings require a biological explanation beyond functional intelligence.
- 3:13:54–3:18:12
The speakers discuss evolution as an explanation of life, then reflect on human meaning, relationships and uncertainty about others’ experiences.
- 41:46–46:00
Lane argues that energy-producing membranes and genome organisation distinguish bacterial growth from the expansion of eukaryotic complexity.
- 37:19–41:46
Lane presents mitochondrial endosymbiosis and genome reduction as central to his explanation of eukaryotic complexity.
- 1:50:12–1:52:24
The speakers discuss the complexity of emotions and speculate about internal conflict in artificial systems.
- 1:37:33–1:41:33
The speakers consider emergence, language models and whether embodied artificial systems might develop experiences resembling emotions.
