Is Life only 3.5 billion years old, or older? #337
The latest research shows life may be 3.8, or even 4.1 billion years old, not 3.5 as shown in the Circle of Life. See here: https://en.wikipedia.org/wiki/Evolutionary_history_of_life
Hi, Thanks for the comment. I agree that the age is an important thing to get right. I think you are referring to the tree that appeared https://www.scientificamerican.com/article/all-2-3-million-species-are-mapped-into-a-single-circle-of-life/ While that tree is based on work of this project, the age isn't. We are hoping to have age estimates for the nodes of the tree at some point, but currently our tree does not have age estimates.
