Charles Darwin's Theory of Evolution work could leave the UK
A fragment from Charles Darwin's On The Origin Of Species, the work in which he outlined his theory of evolution, is at risk of leaving the UK unless a buyer can be found.
The handwritten, draft page, which even includes the words "natural selection", contains Darwin's corrections and reworking and "evidence of pauses for contemplation".
Darwin was born and grew up in Shrewsbury.
Some of the text differs substantially from what was eventually published in 1859, in the first edition of the book.
Arts, Heritage and Tourism Minister Michael Ellis has placed a temporary export bar on the page, from a private collection, and two others from Darwin's later publications, in the hope that a UK buyer will be found.
Written at Darwin's family home, Down House, page number 324 forms part of the English naturalist's conclusion for Chapter 8, which focuses on hybridism and is the only substantial part of the chapter from the draft to survive.
It is valued at £490,000, plus VAT.
Two other pages are from The Expressions Of The Emotions In Man And Animals, and the three combined are worth more than £800,000.
Peter Barber, member of the reviewing committee on the export of works of art and objects of cultural interest, which made the decision, said: "Handwritten drafts of Charles Darwin's books are of the greatest rarity.
"The few surviving sheets, touched by and written on by him, with evidence of pauses for contemplation, or spurts reflecting the rapid flow of thought, bring one closer to the man and his process of creation than perhaps anything else.
"The fragments under threat of export are particularly important. They show how Darwin revised his texts, pinning successive revisions on to sheets containing an earlier draft.
"One fragment comes from his best-known work and indeed includes the words 'natural selection'. But the other two fragments, from his Expression Of The Emotions In Man And Animals, are perhaps even more important.
"Though less well-known than On The Origin Of Species, this book, among the earliest works on behavioural psychology, greatly influenced Sigmund Freud.
"The nation has the chance to save revealing and intimate fragments of two works which, directly or indirectly, have shaped and continue to shape the modern world."
Mr Ellis said the pieces "represent a direct and physical connection" to how Darwin "developed his pioneering work".
He added: "These handwritten and personally signed pieces create an incredibly powerful impression that simply could not be achieved from looking at a digital version or even a published copy."
The decision on the export licence application has been deferred until May 2019, extended until September 7 if a serious intention to raise funds to buy the pieces is made.
