When a research is conducted and results are deduced, scientists tend to perform the experiments again and again to check if the results are similar each time. These multiple set of research again and again is important to check and prove that our results are authentic.
Sometimes, it might happen that there might be some other external factor due to which the results are occurring as seen. Re-checking of the results s important so that it might be made sure that no external factor is the reason of the shown results.

- differential reproduction
explanation:
- Competition
According to Darwin, Competition refers to the struggles that living organisms have to face on day to day basis in order to obtain enough resources (such as food and water) To survive.
- Overproduction
Charles Darwin stated that overproduction is organisms' tendency to produce more offspring than what they could realistically sustain. Darwin believe that they did this because there is always a chance that the offsprings might got killed and unable to obtain food before they can reproduce again. Overproduction ensure that their genetic line can continue for as long as possible.
- differential reproduction
Darwin believe that organisms have a tendency to reproduce with other organism if they have a certain unique characteristics that help them survive. (Such as more strength, better beak shapes, Longer necks, etc)
