Document Summary
A small group of survivors arrives at your door seeking shelter, but you can only save one. You must choose between your sister, a scientist, and a good friend who has looked out for you in the past. And how do they maintain their complex functionality in spite of the destructive force of random genetic mutations: answer: natural selection (ns) Selective transmission: favourable heritable traits are selectively transmitted across generations, example: imagine a population of sh that vary in colour, among other traits. Some individuals are blue and others are red. The blue sh are well camou aged in the blue ocean water and the red sh are must more visible to predators. Therefore, the red sh get eaten more often and so, on average, the blue sh survive and reproduce more often the red sh. Blue sh tend to have blue coloured offspring because body colour is a heritable trait.
