QI: Round 2

Well then, thanks to this answer:

'possibly first, or at least equal first, would be a special bacterium which can bury its own genetic material inside the living cells of flies.  if not the first living thing sent into space deliberately, this would definitely be the first hitch-hiker to leave earth into orbit - as an estimated 20% of all fruit flies carry the bacteria dormant inside their bodies; and fruit flies were sent into space just after the second world war, as the usa and ussr began their programmes to break both the sound barrier and the outer limit of the earth's atmosphere.

so, there had in fact been many living things sent out from earth before the flight of laika the dog - which is often incorrectly assumed to have been first.

You are 2 points better off, putting you on a total of 5.

Now your second question;

What does Bugs Bunny have in common with the Easter Bunny and Brer Rabbit?
