Briefings

A study by Durbin, Lole, and colleagues suggests animals first appeared on Earth 800 million years ago during the Tonian era, challenging the 574-million-year minimum. This implies early metazoans survived Snowball Earth glaciations. Simultaneously, a new study by Domeier, Mathew, and Koyama reveals Earth's poles undergo rapid, episodic true polar wander over 320 million years, driven by mantle and surface interactions, with recent human activity causing minor shifts. Formaldehyde deposition on Mars correlates with water vapor, potentially aiding early life. Key uncertainties remain regarding the exact maximum calibration for animal origins.

Key points

• Scientists estimate the first animals appeared on Earth 800 million years ago during the Tonian era, challenging the 574-million-year minimum established by Ediacara fossils.
• Earth's true polar wander occurs in episodic bursts over 320 million years, with recent human activity causing minor shifts due to dams and climate change.

Context and limitations

The 800-million-year estimate relies on molecular clock analysis of fossil deposits from China and Mongolia; maximum calibrations remain uncertain. Earth's polar wander rates vary significantly over time, and human impact is a secondary factor compared to natural geological processes.
