LUCA
Last Universal Common Ancestor (LUCA) is the most recent population of organisms from which all organisms now living on Earth have a common Last Universal Common Ancestor.
Recent Developments
- Dual Origins Hypothesis: Emerging evidence challenges the singular “primordial soup” model, suggesting life may have had two separate origins within Hydrothermal Vents.
- New Evidence: Recent studies indicate distinct lineages or origins that complicate the traditional tree of life, pointing toward a more complex genesis than previously assumed.
- Source Integration: For detailed analysis of this dual-origin evidence, see Rethinking LUCA: Evidence for Dual Origins of Life in Hydrothermal Vents.
