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.

    But to answer your question - I believe that evolution is real and that it is part of some species' longevity. Not the homing pigeon, however. We killed those off along with a lot of other species.

These universal laws may be applicable to every thing that exits in this universe. Ted lover try thinking differently.

        Survival of the fittest has been demonstrated clearly - the most famous of which is the study of the peppered moth.

        PS - the first paragraph in my preceding post was said in jest. I should have ended it with LOL to make that clear. My bad.
