Rare Darwin book found on toilet bookshelf

LOPNDON, England Christie's auction house said Sunday the book -- one of around 1,250 copies first printed in 1859 -- had been on a toilet bookshelf at a family's home in Oxford.

The book will be auctioned on Tuesday -- the 150th anniversary of the publication of the famous work. Christie's said the book is likely to sell for 60,000 pounds ($99,000).

Darwin's "The Origin of Species" outlined his theory of natural selection -- the foundation for the modern understanding of evolution.

Celebrations around the world this year have marked the 200th anniversary of Darwin's birth.
