Hello, it's me Tim Halford with our final bonus episode of 30 Animals That Made A Smarter

from the BBC World Service.

I love the idea of this brand new series because it brings together some amazing ideas and

inventions, some of which are economic success stories, with remarkable animals.

This is the last time you'll get a chance to download it here, so if you want to carry

on listening to it, I sincerely hope you do, now's the time to go and find it.

It's 30 animals that made a smarter.

You should be able to get it simply by searching for 30 animals wherever you found this podcast.

And please remember, if your podcast app allows, subscribe.

That'll mean you'll get every episode automatically.

And just as I frequently beg you to rate or review 50 things that made the modern economy,

I hope you'll do the same for Patrick and 30 animals too.

It seems to reverberate amongst the trees.
