What causes some species of animals to not evolve that much for millions of years and become “living fossils”? The most well-known/famous example of this is probably the horseshoe crab.
(In other words,) I know what causes animals to evolve, and why they can stop evolving significantly *after* millions of years, but what causes some animal species to not evolve FOR millions of years?
