In this lab students will perform a number of tests to determine evolutionary relationships between a very important (but endangered) plant species, Botana curus and three related plant species (X, Y and Z).
Botana curus is a very valuable plant species because it produces Curol, a certain type of compound used for treating cancer. Curol cannot be produced in the laboratory. Botana curus grows very slowly and is on the endangered species list so it is unable to produce large quantities of Curol. There are three other plant species (X, Y and Z) related to Botana curus that are not endangered. The species that is most closely related to Botana curus is most likely to serve as a source for the important compound Curol and help to cure cancer. Your job is to determine which species is the most closely related to the endangered species Botana curus and therefore the most likely to be used as a source for the important compound Curol.
