Cacti are very young family.

Presumably something akin to Pereskia would be the least ev0lved, but of course even Pereskia has probably changed from the original ancestor of the Cactaceae. The problem for the Cactaceae is there is no genuine fossil record as yet found since they do not preserve well. The only claimed fossil, the so called "Dawn Opuntia" Eopuntia douglasii proved to be a misidentification of a rootstock and not a cactus.
