(Although there is some evidence of life as early as 4.1 to 4.28 Ga, it remains controversial due to the possible ...

The Origin and Diversification of Birds - ScienceDirect - The origin of birds is now one of the best understood major transitions in the history of life. It has emerged as a model case for using a combination of data from fossils, living species, genealogies, and numerical analyses to study how entirely new body plans and behaviors originate, and how prominent living groups achieved their diversity over hundreds of millions of years of evolution 2, 3.
