Indels in AXIN1 and TCP11L1. a A 108-bp deletion in exon 10 of AXIN1 led to a loss of 36 amino acids in all UDT mammals plus four IDT species (Orycteropus afer afer, Dasypus novemcinctus, Condylura cristata, and Sorex araneus) and two CDT species (Rattus norvegicus and Oryctolagus cuniculus). b TCP11L1 has a six-bp-long deletion, leading to the loss of two amino acids in all UDT species. A two-amino-acid deletion also occurred in three IDT species (Chinchilla lanigera, Octodon degus, and Heterocephalus glaber) and marsupials in our dataset. UDT mammals are in blue, IDT in orange, and CDT in green
