    evolution is natural selection. Natural selection is the process where individuals containing specific traits become more likely to survive compared to individuals without those traits. Because certain individuals have a greater chance to survive‚ they become more likely to reproduce yielding offspring that contain the same favored characteristics. As this occurs‚ the number of individuals with preferred traits become more abundant while the population of individuals without these traits begins to decrease

    All living organisms are composed of one or more cells‚ and like any living organism‚ cells are made up of smaller structures that help them function. In the context of cells‚ these smaller structures are referred to as organelles and each organelle has its own unique function that has developed over time. While we are typically aware of how these organelles function‚ how they evolved raises several questions. The main model for how eukaryotic cells evolved over time is the endosymbiont theory. This

    In completing the Tomato Plant experiment I had to apply the scientific method. I observed that my tomato plants were producing less fruit each year. I then questioned some of the elements that may have affected the tomato plants and caused them to bear fewer tomatoes being a deficiency in warmth‚ water‚ or nutrients. I then selected my hypotheses that the plants were in need of more nutrients. Following my hypothesis I developed my prediction which was that my plants would bear more tomatoes if

    naturalist‚ Alfred Russel Wallace (1823-1913) to his mother‚ in an 1854 letter from Singapore. A. R. Wallace went on to propose the evolutionary theory of natural selection (independent of Charles Darwin) in the midst of his 8-year stay in Southeast Asia. Very simply put‚ natural selection means that the species with the more favourable adaptations will survive in the long term whereas the ones with the less favourable traits will become extinct. In March 1854‚ the self-taught Wallace left Britain on
