Explanation of why the others are humanoid, if I remember rightly, is that given similar conditions (ie class 'M' planet) evolution will behave in a similar way. QED. I thought it was a load of old b"££"$%^ but I'm no scientist (or script writer for that matter!).

Anyway, you've all got it wrong. Best Sci-Fi series must be Blakes 7 and Doctor Who - coz their British. But the ultimate is, of course, Fireball XL5!
