[00:00.92]Welcome to the Natural History Museum.
[00:03.16]There's one dream that many people working here share,
[00:05.70]and that's to discover and name a new species.
[00:10.09]It's a part of the Museum's great task to fully understand the complex world we live in.
[00:16.88]We're all over the museum and on expedition, seeking out life in an unexplored jungle.
[00:21.96]I tend to shy away from dangerous snakes.
[00:24.07]Beneath the sea in Sweden.
[00:25.64]There it is. We've found it. We've found it.
[00:27.54]And on the streets closer to home.
[00:30.78]This time we're hearing stories of great explorers
[00:33.57]and joining the people that carry on the difficult and sometimes dangerous tradition today,
[00:39.03]right here in the Natural History Museum, the Museum of Life.
[00:43.41]The truth is you never know when a species that rocks the scientific world is gonna turn up.
[00:49.00]In December 1938, a fishing boat landed at a port on the east coast of South Africa.  1938
[00:55.39]The captain was puzzled by an unusual-looking fish.
[00:59.52]It had a sail-like dorsal fin, a bony skull and fleshy bases to the limbs, as if it was using them to walk on.
