My lecture didn t explicitly address this issue but I want you to do a little extra research and discuss it Changes can occur to DNA called mutations caused by many different factors A mutated gene produces a protein that is differently shaped and therefore functions differently sometimes better sometimes worse sometimes differently sometimes not at all Mutations happen all the time in organisms There are even mechanisms in the cells that attempt to fix mutations In a short discussion I want you to make the connection between mutations and natural selection Which of the three basic conditions of natural selection does the process of mutation relate to Why is it an essential aspect of evolution
