- Overproduction
- Variation Of Offsrping
- Struggle for Survival
- The two flamingos overproduced and made too many flamingo babies. Not all of these flamingos will survive into adulthood to reproduce so their genes will never get passed down.
- Survival Of The Fittest
- The offspring that have survived and matured all have different genotypes and different phenotypes. Some of the flamingos have a characteristic where they have normally curved breaks while the rest had a genetic mutation that has then straight duck-like beaks. This gives us two different variations of flamingos.
- Differential Reproduction
- In the flamingos' habitat, there is a limited amount of fish. This is what the flamingos eat to survive. Since there are so many flamingos but not enough fish to feed them all they have to compete for the limited resource, because the flamingos have different beak shapes or genotypes they will catch fish differently which will give one an advantage starting the process of natural selection.
- Successful Reproduction
- The flamingos with the straight, duck-like beak can catch fish easier than the other flamingos so they start to take away the curved beaked flamingo's food source so some of the curved beak flamingos die while the straight beaked ones thrive. This shows that natural selection has decided the flamingos with the trait of a straight beak had the advantage. While the curved beaked flamingos have the unfavorable trait and start to die. Instead of the four curved beaks flamingos, there are only two left proving that they have the unfavorable trait.
- Now that the straight beaked flamingos have the favored trait they start to reproduce. The offspring all have different genotypes. The main genotype for the offspring would be the straight beaked trait but some of the baby flamingos still have a curved beak. The ones that survive out of that generation of flamingos will reproduce and pass on different genotypes until eventually the dominant trait is straight beaks.
- Now that the straight beaked flamingos are thriving and reproduce more than the curved beaked flamingos the gene pools start to change. The favored genotype is the flamingos with straight beaks so now that the straight beaked flamingos share traits with offspring more than curved beaks flamingos the gene pools are changing to mainly straight beaked flamingos. This shows that the flamingos have evolves to acquire a new strait that will help them survive netter in their habitat.
