[Taxacom] Water Shrews

[Kenneth Kinman]

Hi Fred,
        The genera Neomys and Nectogale (the most specialized aquatic water shrew) are apparently sister groups.  However, genus Sorex is on a different branch, so the American Water Shrew must have become aquatic independently.   See the cladograms (Figures 1 and 2) in this 2016 paper:

Mammalogists,

How are Eurasian (Neomys) and American (Sorex palustris) Water Shrews
related? Were the aquatic adaptations independently evolved, as the
taxonomy would seem to imply?
