A Window Into Evolution – Before The Tree Of Life
All life on Earth shares a common ancestor that lived roughly four billion years ago. This so-called “last universal common ancestor” represents the most ancient organism that researchers can study.

The Nature Of LUCA – The Last Universal Common Ancestor – and its Impact on the Early Earth System
The nature of the last universal common ancestor (LUCA), its age and its impact on the Earth system have been the subject of vigorous debate across diverse disciplines, often based […]

Order Of Amino Acid Recruitment Into The Genetic Code Resolved By The Last Universal Common Ancestor’s Protein Domains
The current “consensus” order in which amino acids were added to the genetic code is based on potentially biased criteria, such as the absence of sulfur-containing amino acids from the […]

The Unfinished Reconstructed Nature of the Last Universal Common Ancestor
The ultimate consequence of Darwin’s theory of common descent implies that all life on earth descends ultimately from a common ancestor. Biochemistry and molecular biology now provide sufficient evidence of […]

Identifying The Last Universal Common Ancestor’s Protein Domains Resolves The Order In Which The Amino Acids Were Recruited Into The Genetic Code
We identified protein domains that emerged early in the history of life. Protein domains whose ancestors date back to a single homolog in the Last Universal Common Ancestor (LUCA) remain […]
