Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens | Lex Fridman Podcast #350

Summary

The main theme is understanding the evolution of life on Earth through phylogenetic trees, which depict the interconnectedness of all living things. Researchers reconstruct ancient gene sequences and species to trace life back to its origins and understand key biological innovations that shaped the planet. The practical takeaway is that by reverse-engineering evolutionary histories from current life, we gain profound insights into the fundamental rules of life and its development, even though much of this past remains obscured by "fog."
