ーーーーーーーーーーーーーーーー

  • 深Explorations of primitive lives have been carried out at deep-sea hydrothermal vents as prime candidates for the origin of life. The interiors of metal sulfide chimneys(*1) are considered crucial environments supporting the emergence of life and its early evolution.
  • They advanced visualization techniques of microbes residing within rocks and revealed the presence of significantly small microbes (approximately 1/10,000th the size of a 1 mm scale) inhabiting the interiors of metal sulfide chimneys.
  • Genetic analysis results indicate the dominance of microbes born in the early stages of life evolution within these chimneys, providing crucial insights into early life ecology.
