Dawkins 3 Questions about Evolution
Richard Dawkins asks three major questions about evolution in chapter 13, "The Long Reach of the Gene", in his book The Selfish Gene. They are:
-
- Why did genes gang up in cells?
-
- Why did cells gang up in many-celled bodies?
-
- Why did bodies adapt a bottleneck lifestyle? (Why do some organisms begin as single cells, grow extremely large and specialized, only to reproduce through single cells?)

A species of deep-sea fish uses a genetically determined bioluminescent lure to attract prey. Fish with brighter lures are more successful at attracting food and have a higher chance of surviving to reproduce. The species produces hundreds of offspring, but only a few survive to adulthood. However, every individual in the current population has a lure of the exact same brightness. Based on these conditions, why is the average lure brightness in this population unlikely to increase over time?
