Evolution or the change in characteristics of populations over millions of years is an important aspect of our human history and studying evolution can help us foresee our future. This is why evolutionary science is an important field of study for scientists. This is a quiz going deep into the science of evolution, and if you are interested in this topic, this quiz is specially designed for you! ALL THE BEST!

    ______ __________ is the addition or removal of alleles from a population when an individual enters or leaves a population.
  • 9. 
    During non-random mating __________ __________ occurs which means due to differences in appearances (like feather color) females will select the most fit mate. 
  • 10. 
    _________ is a severe form of non-random mating that typically occurs in small populations. It results in increased occurence of ________ recessive individuals.
