The Atlantic salmon (Salmo salar) is a fish which lays about 5,000,000 eggs in its lifetime. Only two of these eggs survive to become adult salmon. How does this promote evolution

This promotes evolution by only allowing the strongest to survive, or those with the strongest traits. Leaving fish to natural selection allows for only few to be left, those few are the strongest therefor the ones who’s traits will be passed down due to a limited selection. Since those traits are passed down soon it will show signs of evolution as more of those fish show a cohesive change across the species.
