Moving on to Ethiopia 3.2 million years ago, we witness the beginnings of mankind via a group of australopithecus - a type of ape which, like us, walks upright on two legs. But unlike us, these early members of the human family weren't predators, they were prey. Things get worse for the group as they are hunted by a sabre-tooth cat called dinofelis and fall victim to other dangers such as malaria, rival australopithecus and a rampaging 14-tonne deinotherium.

Back one million years ago, South America was a continent of exotic oversized creatures found nowhere else on Earth - huge terror birds, giant ground sloths and spiky-tailed relatives of the armadillo as big as cars. The deadliest animal of them all was smilodon, the largest of the sabre-tooth cats, with canines like carving knives. The programme follows the fortunes of an individual male, Half Tooth. Ousted from his clan by a pair of rival males, his life suddenly becomes a struggle to survive in this alien world.

Salvador Dali's strange crucifixion is often called the greatest religious painting of the 20th century. Yet its artist was a notorious blasphemer some of whose work had outraged the Catholic Church. The Christ of St John of the Cross by Salvador Dali is the first of two extraordinary crucifixions painted by Dali in the early 1950s. The painting is based on a 'cosmic dream' Dali is said to have had, in which the nucleus of the atom was a figure of Christ himself.
The painting offers a surrealist view of the crucifixion of Christ, and is based on a drawing by the 16th century Spanish friar Saint John of the Cross. But Dali's vision was somewhat unique, using an unusual artistic perspective in which Christ is seen from above. His Christ of St. John of The Cross was inspired by a weird mix of Spanish mysticism and nuclear physics, with his Christ being modelled by a Hollywood stuntman. It's also a masterpiece of painting technique.
