Darwin s Egg of Evolution Puzzle

Can you separate the pieces and rebuild the puzzle?

In 1831 Charles Darwin set off in a naval ship to study natural history in South America, changing the course of science forever. Here he devised his famous theory of natural selection – that all species evolve from other species. This theory is set out in his definitive work, On the Origin of Species, published in 1859. In 1871 he published a further work, The Descent of Man and Selection in Relation to Sex, showing how humans evolved from apes.
