Part A

Use the data matrix below to draft at least three alternate phylogenetic trees.

	Presence or Absence of Hox Genes*
	Hox1	Hox2	Hox3	Hox4	Hox12
Mouse	1	1	1	1	1
Snail	1	1	1	1	0
Flatworm	1	1	1	1	0
Sea anemone	1	1	0	0	0
Sponge	0	0	0	0	0

?1 = gene present; 0 = gene absent.

Label the diagram by dragging the labels to the appropriate targets. ( Note : If two labels can be equally placed in two targets the labels should be placed in alphabetical order from top to bottom.)
