On my family’s farm out in the wheatbelt there are these 3 long star pickets in a triangle formation in a paddock. I asked my grandad what that’s about. He said they used to wrap them in wire and chase the emus in there and shoot them with shotguns to cull them.

Which ancestor? When I think million years ago (Pleisticene ice age), I think of mammalian megafauna like mammoths and giant bison.
