Australia: Platypus & Echidna - S7.E11
In an element common to all five shows of Australia week, David gives an explanation on how Australian animals evolved separately from life on the other continents. It all deals with the splitting of continents from a giant mass of land. With that explanation out of the way, David and Michele, our Australian cast member, track and examine a platypus and an echidna, two unusual animals found only in Australia.
