science 🔬 Life might have started twice, science says
A new study suggests that life on Earth could have begun in two separate ways. Researchers examined bacteria and archaea, finding evidence of two independent metabolic developments. The paper, published on 7 August 2026, analyzed 401 archaeal and 552 bacterial genomes. This points to one genetic code but two separate origins of cellular metabolism. The process involved early chemical reactions being replaced by enzymes over time. 🧬
