Researchers have developed a new method to reconstruct the genetic code of ancient organisms, potentially allowing them to study life forms that existed before LUCA (Last Universal Common Ancestor). This involves creating 'progenitors' – simplified genetic systems that mimic the characteristics of early life, and then evolving them in the lab to observe how complexity arises.
Researchers simulated early Earth conditions with hydrothermal vents and found that archaea thrived, suggesting life may have originated in similar 'chemical gardens' rich in hydrogen and iron.
Researchers from a Spanish laboratory observe, for the first time, the formation of protocells in an experiment simulating the conditions of the early Earth, challenging traditional views on the origin of life.
