Evolution of testicular descent and the scrotum in mammals. Ancestral character states of the testis and scrotum were reconstructed using the ARD (All Rates Different) model. Each internal node in the phylogeny is numbered. UDT: undescended testis; IDT: incompletely descended testis; CDT: completely descended testis. The probability of each state at the ancestral nodes are shown in the pie charts. The value at each internal node is the calculated possibility of the state being scrotal CDT, ascrotal IDT, and ascrotal UDT. An order-level phylogeny is to the far right. All silhouettes are
