As a result, the Australian government began the mass extermination of emus. Later, bounties placed on emus resulted in the death of over 57,000 emus. This event may have caused traits which allowed emus to survive hunting by humans to become more frequent in emu populations.]]> 2017-06-01 01:29:53 UTC https://padlet.com/da426/l0mko2ormnx8/wish/174726964 Geographic Isolation da426 https://padlet.com/da426/l0mko2ormnx8/wish/174728010 It has been speculated by many scientists that struthioniformes originated in the ancient supercontinent known as Gondwanaland. following the separation of the supercontinent, new species of struthioniformes formed as a result of the new geographic isolation]]> 2017-06-01 01:40:53 UTC https://padlet.com/da426/l0mko2ormnx8/wish/174728010 Recent Findings da426 https://padlet.com/da426/l0mko2ormnx8/wish/174729127 Historically it was believed that all Struthioniformes evolved to be flightless simultaneously, however new findings suggest that flightlessness evolved three separate times within the order. Another part of this discovery includes the tinamous, a bird previously excluded from struthioniformes, which is now believed to have coevolved with them. As a result of these new discoveries, Struthioniformes have been reclassified into smaller groups, with the Struthioniformes now only including ostriches. New orders include Rheidae, which includes Rheas,  and the order Casuariiformes, which includes cassowaries and emus.]]> 2017-06-01 01:51:58 UTC https://padlet.com/da426/l0mko2ormnx8/wish/174729127 Dinornis da426 https://padlet.com/da426/l0mko2ormnx8/wish/174729893 500 years old - Holocene]]> 2017-06-01 02:01:55 UTC https://padlet.com/da426/l0mko2ormnx8/wish/174729893 da426 https://padlet.com/da426/l0mko2ormnx8/wish/174735952 2017-06-01 03:03:56 UTC https://padlet.com/da426/l0mko2ormnx8/wish/174735952 Image Sources da426 https://padlet.com/da426/l0mko2ormnx8/wish/174738685
