Example Of Natural Selection During The Industrial Revolution

Natural selection is the driving force in evolution because it is what trait offspring. There are many cases of evidence showing this such as the peppered moth population, the blue mussels, and the finches that we studied.

The peppered is a very good example of natural selection because there is already black moths in the population, but the peppered survived better before the industrial revolution.Though when the industrial revolution comes in the lichens on the trees die and the peppered moth begins to be eaten more by birds and black moths survive and become more common. This shows that the variation in the population helps because if the moths didn't have variation and were all peppered they would have all eventually died out. Natural selection made the colors of moths change to black during the industrial revolution.
The first thing that occurred is the drought in 1977 they saw that after the drought many of the dead finches were the finches with the smaller beaks, while the ones that survived had bigger beaks. This happened because through the drought the most common food was the bigger seeds and the smaller beaked birds couldn't break into those seeds as well as the bigger beaked birds, so because of variation of beak size the more suitable beak size was found and thrived while as you move away from that best size you begin to see less survivors. The thing that is even more amazing is the fact that after that happened it rained for a very long time and they saw another case of natural selection because as it rained the bigger beaked birds couldn't get the more abundant seed from vines so the littler beaked birds survived better in the new
