Using DNA to Classify Life
... Until the mid-1970s, taxonomists usually classified life by morphology (shape). For example, a biologist might compare the structure of forelimbs of mammals. In recent years, biologists have also been able to compare the DNA and thus proteins in different organisms. A hypothesis known as the molecul ...
