Data Analysis:
The reason only the short-necked tortoises are affected because the environment changes and the bushes and trees grow so the Short necks can't reach them, this does not affect the Long-necked tortoises since they can still reach the bushes and trees which is there food. After the 3 generations have passed and we come to the newest generation you can see a drastic change among the numbers of Tortoises in the Area, the short-necked tortoises who have the dominant trait have drastically decreased in numbers, while the long-necked tortoises which have a recessive trait have grown population wise. Even though the short neck trait is dominant the environment has changed in a way that is not good for the tortoises and many of them have died out, while the Long necks were not affected they started mating among each other and produced pure bread long necks.
Conclusion:
As we look through the generations, and have a tortoise with a dominant you would expect that you in an ideal situation as generations pass you would have a lot more of dominant trait tortoises, but in this example that wasn't the case since the environment changed in a way that does not suit the tortoises and the recessive trait ones had an advantage and therefore thrived. So we can conclude that the environment around a specie affects whether it will survive or not, because if the surroundings changed drastically and the creature doesn't have enough time to evolve it can die out. Through this we can also make the conclusion why evolving through generation to generation happens so the creature enables further survival.
