From: Molecular basis of a novel adaptation to hypoxic-hypercapnia in a strictly fossorial mole
Phylogenetic hypothesis of the Family Talpidae. (A) Shinohara et al. 2003 [6], (B) Motokawa 2004 [7], and (C) Whidden 2000 [8]. Line colours refer to the habitats exploited by each: high-alpine terrestrial (black), semi-aquatic (blue), fossorial (brown) and semi-fossorial (green). Note that all topologies suggest that the lineage leading towards present-day eastern moles arose following an extensive period of fossorial evolution.
