0:05:05 > 0:05:09Welcome to Science Fiction, where we answer some of the big questions.
0:05:09 > 0:05:11With some simple answers.
0:05:11 > 0:05:14BUD E, what have you got for us today?
0:05:14 > 0:05:18Today's question comes from Sheila in Inchigeela.
0:05:18 > 0:05:21Is it true that elephants never forget?
0:05:21 > 0:05:23Elephants have excellent memories.
0:05:23 > 0:05:26They have the largest brain of any land mammal.
0:05:26 > 0:05:30Why do they need big brains to stamp around eating grass?
0:05:30 > 0:05:34Elephants live in large, well-structured, social herds
0:05:34 > 0:05:37where the oldest female, the matriarch, is the leader.
0:05:37 > 0:05:39Like the president.
0:05:39 > 0:05:43It's her job to remember feeding grounds, sources of water...
0:05:43 > 0:05:48Where she left the car, birthdays, when to put the bins out...
0:05:48 > 0:05:52Professor, please! Elephants don't learn quickly, though.
0:05:52 > 0:05:56That's like me. In one ear, out the other. Look. Ha-ha-ha!
0:05:56 > 0:06:01It's only through years of experience that they learn to be true leaders.
0:06:01 > 0:06:04- So practice makes perfect, you know? - So there you go, Sheila.
0:06:04 > 0:06:08We can't say for sure elephants never forget,
0:06:08 > 0:06:10but they do have incredible memories.
0:06:10 > 0:06:12As for the professor...
0:06:12 > 0:06:16I'm just a load of old... Hang on, what's my line again?
0:06:20 > 0:06:24I can't... Does anyone remember my line? Help, lads.
0:06:24 > 0:06:27Come here, someone. Give me a hand, will you?
0:06:27 > 0:06:32Turning off all the lights. I can get this, I know I can get it.
