Ganesh: Vestigial Structure in an Animal (2)


Southern Rockhopper Penguin
Eudyptus Chrysocome
+42° 21' 33.10", -71° 2' 58.69"
Emu
Dromaius Novaehollandiae
42.06571,-71.585789

Both the Penguin and the Emu's wings are considererd vestigial structures as its ancestors once used them to fly while these birds no longer use them for that purpose.
