Hi there. I really need help with this one. I don't fully understand and don't know where to begin, so please explain carefully. Thanks. 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)...
