Of course, it is the fault of the library of Cambridge University in England, and it can also be said that it is the fault of Cambridge University. If it is here, this kind of precious notebook of cultural relic level will be well preserved, and the two notebooks will be listed as precious cultural relics by professionals in special departments and put in special museums for protection and preservation for future generations to study and appreciate. In the library of Cambridge University in England, such protection measures were indeed taken from the beginning.

However, this so-called protective measure seems to be completed in full accordance with relevant regulations. You should know Darwin's two precious notebooks, one of which records Darwin's sketch of the evolutionary tree of life when he returned home in 1853, which can be said to be the greatest hypothesis of mankind in the last century-Darwin's sketch of the origin of life, the subversion of mankind and the birth of human species.

In these two notebooks, there are also many important materials that did not appear in the book The Origin of Life at that time, because Darwin believed that if all these important materials were put in this book, it would probably cause more controversy and uproar. It is precisely because of this that these two notebooks are precious. The University of Cambridge, as the depository, failed to guarantee that these two notebooks were foolproof, and according to the University of Cambridge in the United Kingdom,

That is to say, in 2000, these two notebooks probably disappeared in the library of Cambridge University in England, but no one explained this situation. Some people even say that because the library is being rebuilt, these two books may be forgotten by staff in other places. Facts have proved that this explanation is not valid, so I think the head of Cambridge University and the head of Cambridge University Library are in the whole.
