There are hundreds of species of cacti in the world, that differ greatly in many features, but all thrive in dry environments. With the exception of one bird dispersed cactus species (which we will ignore), all cacti species are only found in North and South America. What about this situation supports descent from common ancestry?
Group of answer choices
a.) Cacti are well adapted to dry environments, which would not be expected under separate ancestry.
b.) Cacti differ in many features, as expected under common ancestry
c.) Cacti don’t occur in dry environments in Africa and Asia, where we would expect them to also occur under separate ancestry
d.) All of these provide clear support for common ancestry over separate ancestry
