"Anti-aging and longevity are two different things."
Depends on what you precisely mean by longevity. The word used to mean "living long naturally", but the meaning has been shifting towards lifespan and healthspan extension in the last decade or so. So if someone now says that they are interested in science of longevity, they probably mean "reaching 110 years of age in good health".
For that, you need anti-aging tech definitely. Our natural lifespan is shorter and breeding humans for natural longevity [0], while theoretically possible, would take several thousand years.
[0] Theoretically, you could take a big group of humans who are still fertile at 40, let them reproduce and, in the next generation, lift the limit slightly, say, to 40,5. After tens of generations, you will have a group selected for longevity, because late fertility tends to align with longevity. But given how long our generations are, that would take a long, long time.
