Evidence for the big bang was initially thought to be a mistake in the recording. Jet streams in the upper atmosphere were revealed by the dust emitted by Krakatoa and a collection of interested citizen scientists. In the second three episodes about the genius of accidents in science, presenter Adam Hart explores two stories of unexpected observations. Sometimes accidental discoveries are bigger than you might expect. Picture: Moonlit Coast, Credit: shaunl/Getty Images

Professor Ben Garrod and Dr Jess French get under the skin (and blubber) of the California sea lion, to crack the key to its success both on land and at sea. Its ability to dive hundreds of meters down, keep warm in icy waters, and run on land, can all be explained through its unique internal anatomy. They are joined by zookeeper and sea lion trainer Mae Betts, who adds insight into the intelligence of these sleek marine mammals. Co-Presenters: Ben Garrod and Jess French

Wild Inside: The Sea Lion

The tiny sap-sucking aphid, at just a few millimetres long, is the scourge of many gardeners and crop-growers worldwide, spreading astonishingly rapidly and inflicting huge damage as it seeks to outwit many host plants’ natural defences. With insights and guidance from aphid expert George Seddon-Roberts at the John Innes Centre, Norwich, some delicate dissecting tools, and a state of the art microscope, Professor Ben Garrod and Dr Jess French delve inside this herbivorous insect to unravel the anatomy and physiology that’s secured its extraordinary reproductive success, whilst offering new clues as to how we could curtail its damaging impact in the future.

Wild Inside: The Aphid

Ominously called the lamb vulture, there are many myths and misconceptions surrounding the bearded vulture. Flying the mountainous ranges across central Asia and eastern Africa, with a wingspan of almost three meters, the bearded vulture is am impressive Old World vulture. Prof Ben Garrod and Dr Jess French are looking past the beautifully coloured plumage, and delving deep inside to learn what this bird of prey really eats and what keeps its great wings aloft.

Wild Inside: The Bearded Vulture

Wild Inside returns for a new series to take a look at some of our planet’s most exceptional and unusual creatures from an entirely new perspective: the inside. Whilst we can learn a lot from observing the outside, the secrets to the success of any animal – whether they swim, fly, or hop – lies in their complex internal anatomy. How do these wild animals survive and thrive in harsh and changing environments? To truly understand we need to delve inside. Professor Ben Garrod, evolutionary biologist from the University of East Anglia, and expert veterinary surgeon Dr Jess French, open up and investigate what makes each of these animals unique, in terms of their extraordinary anatomy, behaviour and their evolutionary history. Along the way, they reveal some unique adaptations which give each species a leg (or claw) up in surviving in the big, wild world. The series begins with an icon of the outback – known best for its hopping, boxing, and cosy pouch – the red kangaroo. Despite the immense heat and lack of water, these marsupials dominate Australia, with their evolutionary history driving them to success. From the powerful legs which allow them to hop up to 40km an hour, to an unexpected reproductive system that keeps their populations plentiful, Ben, Jess and marsupial expert Dr Jack Ashby reveal a mammalian anatomy which holds many surprises.

Hannah Fry explores two tales of data and discovery. A young researcher gains access to a secretive data set and discovers a system causing harm to the very people it is supposed to help.  One day a student makes a discovery which, if true, could shake the intellectual foundations of a global movement, and undermine politicians around the world. Producer: Lauren Armstrong Carter
