Yes, nature intentionally made telomeres shorten in several animals including humans. Genetic variety results in an increased chance of a species surviving rapidly changing environments. Eliminating the longer lived increases the genetic variety within a species by favoring breeding among the shorter lived. Telomere shortening results in the elimination of the longer lived.
