In every way you can think of this skull is not human in either its design or its DNA. When we tried to recover its DNA we found that its mitochondrial DNA recovered very easily, meaning that its mother is human. But its nuclear DNA which contains the DNA of its mother and its father was not able to be recovered in six attempts. So that tells us its DNA, its nuclear DNA, is not entirely human. So we think we have in this skull the first bonafide provable evidence of life from beyond Earth.
