Obscure Who link
Did anyone else pick up on the similarities between the settings of The Doctor's Daughter and The Ark? When they reached the spaceship at the end, I was really hoping for an explicit line about "the Steel Sky", or perhaps an elephant in the undergrowth. As it was, it looked very similar to the jungle where the Doctor, Steven and Dodo met the Monoids all those years ago. So perhaps there was a general policy of sending out mixed crews of humans and humanoids; in one case, the humanoids might be half man, half fish; in another, they might be half human, a quarter Beatle, and a quarter ping-pong ball.
