I was able to observe that in the wild you need that favorable trait so that you are able to reproduce and continue down your genotypes for the near generation of you species to inherit. Igained useful skills such(prenominal) as how to settle down the next generations existence by analyzing results from experiments I conducted relating to the bird populations
