Summary Dawkins Switch To Natural Selection

Dawkins now starts to switch to natural selection. He begins with the discussion of plants have a part in insects and birds evolving. The plants bride the insects and birds with food. They are drawn in by the rich good taste of the flowers nectar. For bees, the flower leaves a sort of trace to guide them. This trace is in fact ultraviolet pigments that draw in the bees. Not only bees, but other creatures are able to see these pigments as well. Their systems are suited to view certain shapes, colors and arrangements appealing to them. Humans can only see flowers very plain, but to these creatures they see a more detailed view. To insects and birds, a large area of flowers is equivalent to the big apple to us. He speaks about one interesting insect called the Angraecum sesquipedale. This insect …show more content…
He uses peacocks and their features for an example. He states that peacocks would have better luck with getting away from predators if they had more helpful feathers and smaller tails. Surprisingly, birds were seen to have breed caterpillars. Also, caterpillars are very similar to snakes. This could question if they share a common ancestor as well as many other creatures. The deep sea angler fish is one that should be paid very close attention to. They go to the darkest part of the sea to catch their dinner. The interesting thing about this particular fish is that its spine stretches out to outside of their head. On the end of the spine, there is what seems to be a light that shines in the darkness in order to see their prey. The light is also what they use to attract in other fish that they then eat. The downside to this fish is the ones that have lights that are not as appealing. For the ones with this unattractive light, they are more likely to die from lack of food. Due to this flaw, offspring from the living one will probably be born with the better light, the fish then evolves over time to create better
