How does natural selection affect reproduction?

Answer 1

If an organism has a trait that doesn't allow it to grow to maturity, this may prevent it from reproducing.

The classic example of this is the peppered moth. In the pre-industrial age, trees in Europe were light coloured so those moths with light coloration thrived and were able to reproduce and pass on this trait to the offspring. Consequently, if you were a dark coloured moth you would probably get eaten by birds or whatever and therefore never have the chance to reproduce. In the same example in Europe, when pollution discoloured the trees and made them dark coloured, the entire situation changed - dark coloration was in and light was out!

Natural selection influences reproduction by favoring traits that enhance an organism's reproductive success. Traits contributing to increased survival and reproduction are more likely to be passed on to the next generation, shaping the population over time.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
