The infinite site assumption implies that, every genome position mutates at most once in the evolutionary history of a tumour. With this assumption, one could easily exclude convergent evolution. Here, """ Convergent evolution is a common theme in the evolution of animals. It occurs when two unrelated species independently evolve similar traits to cope with specific evolutionary challenges, like living in ice-cold water or eating ants. Sometimes convergent evolution is so powerful that creatures that began as entirely different animals start to look almost the same, as is the case with the skulls of the extinct marsupial Thylacine and the living Grey Wolf."""
Why is this? Could anyone please help to clarify more about it?
