Animals with traits that are beneficial to the environment can live longer and potentially contribute more to the gene pool.

The latter is all that matters (biological fitness, or how many viable offspring are produced) in natural selection. Lifespan and any greater purpose (benefit to the environment) are not applicable.

All tautologies are truisms, but not all truisms are tautologies. - 06/08/2011 09:38:12 PM 1052 Views
