Blog #8 (What I've Learned)

Blog 8 Your choice talk about something you learned or ask a question about something that is confusing you


In this semester I have learned about Natural Selection. Natural Selection is the process by which traits become more or less common in a population due to consistent effects upon the survival or reproduction of their bearers. It is a key mechanism of evolution


An example of Natural Selection are the Finches. The finches were birds that can have long or short beaks. The finches had to get thier food by poking thier beak through holes in trees and eating bugs inside beaks. The longer beaked finches were able to survive because they were able to get food through the holes, while the shorter beaks could not get food and were not able to reproduce.
