The only thing really necessary for evolution is production of offspring and accumulation of mutations. If you think about it, organisms that divide themselves to reproduce themselves, such as bacteria, some algae, and even cancerous cells, are essentially immortal, making copies of themselves and living with the identity of the original organism until the copy acquires mutations. Lifespan is merely something that wasn't selected for in the evolution of multicellular organisms, while the production of strong offspring was selected. Lifespan is something we can manipulate, and indeed we have, especially in the past few hundreds of years. When we figure out how to avoid irreversible cellular damage indefinitely, then we will have beaten death.
