Aders the book provides a beautifully written view of evolution as a process based on interdependency and thei nterconnectedness of all life on the plane. Sion between bacteria and the new cells is inact the most dramatic in all biology She goes on to say that All cells either have a nucleus or do not No intermediates exist The abruptness of their appearance in the Kosingas Onaj što nauči mrak da sija fossil record the total discontinuity between livingorms with and without nuclei and the puzzling complexity
