As we are programmed to die after a certain period. I believe species are also programmed to die after a certain period.

I believe every species has a definite life span on our planet earth and we may call it " species span", after that it becomes extinct whatever you may do. Ever entertained such idea ? Ever analysed what happened to neanderthal man, homo erectus etc why they became extinct or Why growth rate of caucassian is nearing zero or in the negative? Is the life span of species is also programmed? Even our earth also has a limited life span, its not going to be there for ever.

    For example, there is a species of bird, some of its members evolved and out competed the original, the original becomes extinct or is folded into the new species through interbreeding.

      Mar 14 2013: Sometimes facts are there in front of eveybody to observe and there are established ideas to explain their occurrence. You are right I am challenging those established ideas with no evidence. Also we donot have conclusive evidence to prove why humans or for that matter any animal has a limited life span , are we programed to die after some time ? If we are than why not our species? I believe even Sun is programmed to die after some billion years later, it also has limits to its life span.
