DAVID's comment: These are transitional forms of mammals, but the transitions are giant gaps in physiology again unsupportive of the gradualism proposed by Darwin.

dhw: Just to clarify: transitions are transitions, thus providing evidence for evolution. Although Darwin thought gradualism was essential to his theory, many evolutionary scientists disagree with him and accept that there have been saltations.

Unexplained saltations unless God is accepted. Darwin's only contribution is common descent after life began.
