Origin of photosynthesis may go further back than estimates from 50 years ago
Analyzing ancient rocks has helped push back the date when photosynthetic organisms first emerged by nearly a billion years.
- Paleontology
Oldest microfossils suggest life thrived on Earth about 4 billion years ago
A new claim for the oldest microfossils on Earth suggests that life may have originated in hydrothermal vents, but some scientists have doubts.

Microbes survived inside giant cave crystals for up to 50,000 years
Microbes trapped in crystals in Mexico's Naica mine may represent some of the most distinct life-forms found in Earth so far.
