Reconstructing Early Microbial Life

by Keith Cowing

For more than 3.5 billion years, life experienced dramatic environmental extremes on Earth. These include shifts from oxygen-less to over-oxygenated atmospheres and cycling between hothouse conditions and global glaciations.

A Dynamical Systems Perspective On The Celestial Mechanical Contribution To The Emergence Of Life

by Keith Cowing

Biological activities are often seen entrained onto the day-night and other celestial mechanical cycles (e.g., seasonal and lunar), but studies on the origin of life have largely not accounted for […]

Building and Maintaining a Habitable World and the Early Conditions that Could Favor Life’s Beginnings on Earth and Beyond

by Keith Cowing

The Hadean, once thought to be uninhabitable and tumultuous, has more recently been recontextualized as a clement time in which oceans, land, and life likely appeared on Earth. This non-exhaustive […]

New Study Sheds Light on Ancient Protoribosome and its Role in Early Life Evolution

by Keith Cowing

Scientists have uncovered new insights into the protoribosome, a molecular fossil within the ribosome, which plays a key role in the origin of life on Earth. This research, published in […]
