What does this futurist Anti-Aging Genetic Engineering science mean?

In this infographic in Step 6 it describes "evolutionary drugs"- using artificial selection to create symbiotes that increase lifespan. I don't understand what this means? What are evolutionary drugs and what would they create? Symbiotes? I'm so confused.
