How did life arise on Earth? Steven Strogatz speaks with the Nobel Prize-winning biologist Jack Szostak and Betül Kaçar, a paleogeneticist and astrobiologist, to explore our best understanding of how we all got here.
RNA and peptides coevolving in the primordial world might have jointly served as a precursor to the modern ribosome.
When researchers gave a genetic molecule the ability to replicate, it evolved over time into a complex network of “hosts” and “parasites” that both competed and cooperated to survive.
The discovery that short peptides can form spontaneously on cosmic dust hints at more of a role for them in the earliest stages of life’s origin, on Earth or elsewhere.
A mathematical model shows how a thermodynamic mechanism could have made protocells split in two.
New work suggests that the radiolytic splitting of water supports giant subsurface ecosystems of life on Earth — and could do it elsewhere, too.
