Diversity In Living Organisms
What indicates that the classification of life forms will be closely related to their evolution?
The characteristics that came into existence earlier are likely to be more basic than characteristics that have come into existent later. Therefore the characteristic that came in earlier will be common and found in more organisma as compared to the one which came in later as it is found in fewer. So, we can predict that the organisms having the latter charactristic evolved during the later stages. Thus, the classification of life forms is closely related to their evolution.
