Shallow coalescence Marine teleosts tend to show very shallow coalescence in haplotype networks, indicating a shared common ancestor on a timescale much shorter than the age of the species (Grant & Bowen, 1998). Furthermore, pelagic teleosts tend to have shallower coalescence than coastal fishes (Graves, 1998). The causes for this phenomenon have been debated in the literature for over 20 years (e.g., Copus et al., 2022).
