I just realised that the shorter an organism's lifespan the quicker the evolution of its species is. Do biologists already know this or is this new?

actually, the younger they have kids the quicker the evolution. this is why you can see bacteria evolve in an afternoon with a microscope

This, you can have insects that breed multiple times, but the rapid growth to imago is key. My mosqs families might as well be islands of sparsely related species, and they're relatively recent in terms of insect evolution.
They can live quite long, but the more rapid species are the ones with melanized mutants, and anopholine mosqs modify their own ribosome copy number, something an animal who invests in long-lived cells and their young wouldn't do.
They don't have DNA methylation, they don't adapt to an environment within a generation, the epigenetics are all transgenerational systems for immune response or directing developmental stages. Rapid adaptation between generations (hell, between laying periods according to an australian paper) instead of robustness. It's a strategy that seems to work.

Darwin is for high school students. Get a new fucking model, it's called punctuated equilibrium: Creature evolves, creature fills a role well enough, evolution stops. Disaster happens? Repeat cycle

Check out squirrels some time. They are always in fast mode. Constantly looking out for predators at break-neck speeds. Squirrels live a life that is very fast in every aspect.

Panspermia is most likely false but pseudo panspermia is a very robust conjecture with actual evidence backing it up. It also kinda disproves panspermia because organic compounds are randomly found throughout the universe so they're not rare at all. Earth was likely seeded with naturally formed organic compounds from which life arose and most likely did not develop life from scratch but neither was seeded with preexisting life. This still keeps life very rare but not one in a gajillion impossibly rare. Personally, I wouldn't be surprised if there was other life in the known universe but it's so rare that humans are the only intelligent life that exists.

that'a why biologists love fruitflies as their macroscopic model

How many stars are there? How many planets? I think if this number was right we would have found signs of life on other worlds by now.

This is true but not the full answer. generation turnoever is significant but so rate of mutation, population size, envronmental factors...

It's well understood that generation length and number of offspring help species both adapt faster and accumulate mutations faster, yes. This is usually correlated with lifespan/maturation speed for obvious reasons (r-strategy), and often associated with adaptations that themselves increase the mutation rate (shoddy DNA replication/repair, less defenses against mutagenic substances, more transposable elements.)
Sorry anon, it's a pretty trivial deduction.
