Creationism versus Evolutionism

Evolution by natural selection is a result of evolution that leaves organisms well adapted to their current population but does not make a perfect organism (Smock 2014). Male guppies have shown over the past 200 years to have more or less colorful patterns decorating their bodies. Studies have shown that male guppies have more colorful body patterns in areas where there are no predators and more conservative colorations when in hostile waters (Futuyuma 2009). A 1980 study proved that once guppies were moved to safer waters, in the next later generations, more colorful male guppies began to appear (Futuyuma 2009). The guppy applies to the first rule of natural selection that there is variation in a trait in an organism in a population because some guppies will have less pronounced colors, some will have more pronounced colors. Whichever environment the guppies are in determine which guppies will likely survive (Futuyuma 2009). The second rule is that the trait must be partially heritable which is true in the guppies’ case because the surviving guppies will pass the mutation, which is always totally random, down to their offspring allowing them a better chance of survival (Futuyuma 2009). The third rule is that the trait must give the guppy a higher level of fitness and more able to pass on the trait to its offspring, which is true here because in dangerous water the darker colorations will help the guppy blend in and stay alive while the brighter guppies will be targeted more and in safe waters the lightest colored of the guppies will attract more mates to help pass the trait along to their offspring (Futuyuma 2009). Mutation is the changing of form or quality and that is what the change of color is classified as and that over a pe...
