    behaviors. Life history theory suggests that reproductive tendencies, or “life history strategies,” are part of a complex system of species traits, or “life history characteristics.” Parent organisms display reproductive strategies that essentially represent calculated trade-offs based on the anatomical, environmental, and ecological characteristics of their species. (For example, my parents strategized against having another kid because I was such a handful.) We knew they were different, we…

    It has both modern and primitive (apelike) features, and is really baffling the scientists. Naledi had a very tiny brain and large body, which doesn’t make sense and its hands and feet were almost modern. It’s a whole new species of Homo Naledi that is still being dated, it might be 3-4 million years old. These Homo Naledi were found in a cave, not washed in, or drug in by animals, and there is no other way in but down a chute. The archaeologists think they may have buried…

    Darwin created Darwinism which says that species evolved by natural selection and those that could not adapt did not evolve as much. In the late nineteenth century a man named Herbert Spencer adopted a concept called Social Darwinism. Social Darwinism was an excuse to divide people based on race. This theory ultimately…

    qualities are passed on from parents to offspring to make it more likely for an organism to survive and successfully reproduce. There are eight basic steps to the process of Natural Selection, the first step is that species reproduce faster than our food sources which means that species are overproducing and without predators overproduction will become an issue as well…

    This excerpt from the book Literature and its Times has an in depth analysis of Victorian Life and provides a brief biography of Robert Louis Stevenson. According to Moss, Stevenson was very involved with Calvinism in his childhood which contributed to an active imagination. This active imagination may have contributed to the creation of The Strange Case of Dr. Jekyll and Mr. Hyde. For example, Moss shows how religion inspired Stevenson’s writings: “Furthermore, Dr. Jekyll’s resignation and…

    planet and the assertion that species do evolve and the age of the planet. The importance of this debate survived countless generations of scientific inquiry because it was a critical part of step towards a greater quest to explain the existence of life. For many centuries, the evidence on evolution was often unsubstantiated until Charles Darwin, developed the foundational ideas of evolution, creating a set of postulates that when adhered to, could determine if a species is able to evolve. The…

    Mutations are the building blocks of species evolution, without which homo sapiens would never have existed. Mutations appear randomly in individuals of every species and can be harmful, beneficial, or have no change on the individual’s ability to survive and reproduce. Harmful mutations can cause the organism to fail at reproducing which deletes that mutation from the population’s gene pool. Beneficial mutations have the opposite effect, resulting in a higher frequency of the specific mutation…

    Evolution is the change in a period over time. Scientist use evidence of evolution to prove that there was a change in organisms over time. If the evidence is present, scientist would come up with theories that are reasonable enough to have support from the pre- historic time frame. The lab is to show the people how living things came to be in the present day. Including how fossils as evidence explain why there maybe certain functions were used in the early stage of an organism. Hypothesis: If…

    differences from their parents deals with the concept of descent with modification through natural selection. The concept of evolution through natural selection was first conceived by Charles Darwin and is used to explain how and why populations of species change over time (Laboratory Exercise 4 2015). Darwin’s theory was based on three conditions that are necessary and sufficient for natural selection. There must be variation in a trait in a population, the trait must be heritable, and there…

    the voyage, he was also able to observe that island species were related to each other and to other species in other close areas. Finally, Darwin assumes that there must be a geographic distribution of species, because organisms on opposite locations seem to be related due to similar ecological conditions. In other words Darwin concluded that different but related species may live in different habitats but in the same local area and that species may inhabit separated, but in ecologically similar…
