Using the Maximum Parsimony Program
Entering Data
The Maximum Parsimony program returns phylogenetic trees
calculated from a sequences' small and large parsimony scores. (For definitions of Small and Large
Parsimony, click here ).
Maximum Parsimony:
When entering data for the Maximum Parsimony Program, a number of sequences should be
entered. Sequences should be of the same length. Labels should be added to the left of the sequence, followed by a colon, then the sequence. A single return should be entered between sequences, as demonstrated below:
| Horse: | GATTACA |
| Cow: | CTGGATT |
| Pig: | ACCTGAG |
| Monkey: | AAATTAC |
| Dog: | TTGCGCA |
| Cat: | CGTGAGA |
| Chicken: | GGTACAA |

PHYLIP:
PHYLIP (PHYLogeny Inference Package) is a program written by Joe Felsenstein of the University of Washington
that returns a visual output of phylogenetic trees. The Maximum Parsimony program you are using calculates the
most parsimonious possible trees, which are then rendered visually by the PHYLIP program. For more information

program, click here.
