Riddle me this...
A certain large animal lives happily and thrives here on Earth.
One day, every single one of these critters is wiped out by a
mysterious disease which affects only this particular animal.
There are none left anywhere on earth -- they are all gone.
About a year or so later, they begin to reappear on Earth again.
How can this be?
asked in riddle
Can't recall which animal it is, but i'm sure there some cross between two animals that then can't reproduce itself - hence you'd need two of the original animals to mate.
If the animal was man and mankind was wiped out on Earth, then any astronauts in orbit returning to Earth would be the re-appearing animal.
Probably not the right answer but it's logical. Can I have my Doggy prize now?
