Study the table, and figure out the order of evolution of each character. You have been given reason to believe that, based on the fossil record, Xenite A is the ancestral species. Create your cladogram for the Xenites.
Table below:
Xenite A. no spines, no eyestalks, no tail, no mouth
Xenite B. no spines, yes eyestalks, no tail, yes mouth
Xenite C. no spines, yes eyestalks, yes tail, yes mouth
Xenite D. yes spines, yes eyestalks, no tail, no mouth
Xenite E. yes spines, yes eyestalks, no tail, no mouth
Xenite F. yes spines, yes eyestalks, yes tail, yes mouth
Based on the information given, the order of evolution for the Xenites would be as follows:
Xenite A -> Xenite B -> Xenite C -> Xenite D -> Xenite E -> Xenite F
Here is the cladogram for the Xenites:
