![]() ![]() Following many years of exploration, Darwin’s theories of natural selection and evolution were published in his book ‘On the Origin of Species’ (1859). He was born in 1809 in England, spending his life travelling the world as a geologist/biologist and naturalist. As the pioneer of many evolutionary theories, Charles Darwin is a focal and highly significant individual when considering modern day natural selection. This idea was first introduced to be explained by naturalist and biologist, Charles Darwin, through his extensive research and findings. ![]() Through time, natural selection has occurred so species may increase their chances of survival. Natural selection can be defined as a “process that results in the adaptation of an organism to its environment by means of selectively reproducing changes in its genotype, or genetic constitution.” (The Editors of Encyclopaedia Britannica, 2018) The purpose of this research is to explore natural selection, and more specifically, directional selection, and its impact on both past and present flora and fauna. This experiment fulfils its aim whilst also offering a multitude of possibilities and questions for future experimentation and research. Some populations (such as the green and blue ‘worms’) were able to thrive due to their phenotypical traits and subsequent selective advantage, while others (such as the red, yellow and plain ‘worms’) declined in population due to their phenotype. Therefore the experiment models directional and natural selection as the phenotype of the ‘worms’ significantly influenced their chance of survival. ![]() It is speculated that these results occurred due to the phenotypical similarities or differences the coloured ‘worms’ had with a typical chicken diet. In contrast, the plain (no dye), red and yellow coloured pasta were preyed on most, diminishing in numbers during the experimental period. After four repetitions, the ‘worms’, coloured green and blue were shown to be least attractive to the chickens, becoming superior by far outnumbering the other colours in population size. The five phenotypes were placed amongst chickens in an enclosed space to track the most preyed upon colours in a two minute time frame. Bucatini pasta was utilised to model worms, separated into 5 groups, each a different colour (blue, red, yellow, green and plain). The experiment focuses on the impact phenotype (colour) has on minimising predation, therefore enabling a population to survive and expand. In particular this report explores directional selection where the phenotype of flora or fauna changes/adapts, after certain interactions, to suit their environment. The experiment aimed to model natural selection in order to further prove and explain this phenomenon. Huh, maybe war doesn't change? Someone should write that down.CONCLUSION What is the influence of phenotype (colour) on the predation of worms by chickens? ABSTRACTįrom the beginning of the earth to the end of the universe, natural selection will remain relevant. Encroach upon your opponent's territory until there is nothing left for them to fight for! Conqueror be conquered! Dominate with extreme prejudice or bow down to the iron heel of those who would have you on your knees. Upgrade your units, your items, and your various battlements. All of them with various types of shields, weapons, and whatever. You'll be in charge of an entire legion of stick troops throughout the ages. And that is what this war is about: Territory. Sometimes we fight over religion or resources, or philosophy, but mostly its territory. The weapons got bigger, louder, faster, eventually, we split the atom and now robots do all the fighting for us, yay! So, yeah. At some point someone discovered gunpowder. It used to be fought with sticks and stones, and then we discovered flint rock and made bows and arrows. Territory War is a free strategy game of attrition. ![]()
