Further Proof That Evolution Happens Without DNA

While it is popularly think that phylogeny occurs through mutations in DNA , that ’s simply not true . Now scientists have more grounds that development function even among proteins that have no DNA .

Infectologists at Scripps Institute discovered this evolutionary behaviour by read the behavior of prions , a character of protein you may know because mutated prions in the brain cause mad cow disease . What the researchers key out was that when they moved prions from brain cells to a new environment , the proteins shift . The prion best - suitable to the Modern environment were slightly unlike from those that bring home the bacon in brain cellphone , and those come to dominate the universe . When the prion were moved back to the brain cells , however , the prion population shifted back . allot to BBC News :

Charles Weissmann , head of Scripps Florida ’s department of infectology who head the written report , said : “ On the face of it , you have on the dot the same mental process of mutation and adaptative change in prions as you see in viruses . . . This imply that this pattern of Darwinian evolution seem to be universally active . In virus , chromosomal mutation is connect to change in nucleic Zen chronological sequence that lead to immunity . Now , this adaptability has be active one grade down- to prion and protein fold – and it ’s cleared that you do not need nucleic acid ( DNA or RNA ) for the unconscious process of evolution . ”
