Picture the last two hundred years without the publication of Darwin's "On The Origin of Species" -- how might the scientific conversation have developed? What were the influences in Victorian England during Darwin's youth, and how tenuous was his opportunity for sailing on the Beagle's voyage?
The secret lives of the world’s most mysterious cats are brought to light by advances in remote and low-light filming technology. In South Africa, we follow the nocturnal pursuits of the tiny black-footed cat that stakes its claim to the title of the world's deadliest, and in remotest Mongolia we reveal the rarely seen Pallas's cat, at home with her kittens - she hunts by looking like a rock. Finally, in South Africa, we uncover the secret of the serval that thrives amongst the futuristic landscape of Africa's biggest industrial complex. These are remarkable cats, with surprising lives in extraordinary places.
