Researchers found mud containing the genome of an ancient unknown animal. It does not resemble any living being of the present day, a kind of large camel without a hump, long-necked and prominent nose. Science is in turmoil, no one is able to use this information profitably! The genetic material will be lost in 60 minutes because it will be damaged in contact with the air. What to do? To try the last chance, a medium manages to contact the great Darwin from beyond the grave and gets a message from him … but it is an enigma, which in turn leads to another enigma … and so on … The only reason is that he can help to add a branch to the phylogenetic tree of mammals!
