Meaning, does evolution occur with a purpose? I understand that there is no true purpose as to why evolution takes place, but, to my knowledge, it can be labeled as a process. For example, the panda bear with the “thumb” (a.k.a. the sesamoid bone). Would the panda acquire that trait that would cause the bone to evolve if he had not migrated away from his original niche? The environment does stem to the members of the species adapting some physical traits, but their offspring will not automatically be born with those traits. Thus, what I am essentially asking is does evolution occur for a reason? Does variation play a significant role since without variation, all species members of a species would be the same and if they were all identical and they shared traits selected for, then that would cause that group of species to disappear? Therefore, evolution occurs to prevent extinction? Am I right? I know this is kind of confusing, but some please, please help me!!
