Relative time constraints improve molecular dating

Abstract : Dating the tree of life is central to understanding the evolution of life on Earth. Molecular clocks calibrated with fossils represent the state of the art for inferring the ages of major groups. Yet, other information on the timing of species diversification can be used to date the tree of life. This is the case for instance for horizontal gene transfer events and ancient coevolutionary relationships such as (endo)symbioses, which can imply temporal relationships between two nodes in a phylogeny (Davín et al. 2018). This can be particularly helpful when the geological record is sparse, e.g. for microorganisms, which represent the vast majority of extant and extinct biodiversity.
