The biochemist Nick Lane thinks life first evolved in hydrothermal vents where precursors of metabolism appeared before genetic information. His ideas could lead us to think differently about aging and cancer.
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.
