3. Linnaeus and other early scientists classified organisms based on visible traits. Today, scientists generally use
cladograms based on DNA and other evolutionary evidence to classify organisms. Why have most scientists
changed their method of classification?
a. Cladograms are relatively small and the information in them is easy to manage.
b. Cladograms can compare more animals at one time than traditional classification methods.
C. DNA evidence supports the idea that species that look similar are always more closely related than species
that do not
d. DNA evidence often shows that species that s hare characteristics but look different can be more closely
related than species that look alike.
