It isn't "necessary for evolution" but rather an inevitable consequence of evolution. Quite different. Aging species outcompete ageless species in near every niche, with a few interesting exceptions. That says nothing about aging other than how effective a strategy it is in evolutionary competition - if living every moment of life in agony was an effective strategy, we'd all be doing that.

Evolution in the natural sense, of course, has little to do with our future now that we're getting our hands on the controls of biology, and then technologies that can replace biology. Though in the general sense it will play an important role in every culture build by humans.
