Abstract

Abstract Overview

The Earth, distinct among inner planets, maintains an oxidizing atmosphere, a stable temperature, and a consistent geomagnetic field (GMF). This field plays a pivotal role in protecting life and maintaining environmental stability.

Key Functions of the GMF

• Shields life from solar wind and cosmic rays.
• Maintains the atmosphere, aiding in environmental stability.

Influence on Life's Origins

From archaea to multicellular organisms, living entities might have leveraged the GMF for spatial orientation since life's inception.

Impact of GMF Changes

Alterations in the geomagnetic field, such as pole reversals, significantly weaken the field or lead to temporary disappearances. These events could induce severe climatic shifts and increase mutation rates due to heightened exposure to solar wind and cosmic radiation.

Comprehensive Analysis

The study reviews extensive data on how the GMF influences various life forms, highlighting its essential role in both protection and potential risks associated with its fluctuations.

Conclusive Insight

A stable GMF positively affects living organisms, while its reduction or loss portends negative implications. This influence is also crucial in considering the survival of terrestrial life beyond Earth and ramifications for life emergence on other planets.
