The picture below has species I-IV (teg = species in this case)
and traits/characteristics (a-j). Classify species I-IV based on
the traits (a-j) and draw a parsimony tree.
What effect would it have on your classification of the species,
if it was based on the amount of shared characteristics/traits?
Does it change anything if 0 (zero)...
