    Poeciliidae Evolution

    • 907 Words
    • 4 Pages

    phylogenetic comparative methods were used to test for correlated evolutionary traits in Poeciliidae (Pollux et al., 2014). For one, the comparative method is applied to examine the potential conflict-driven shifts in sexual selection associated with the evolution of post-fertilization of maternal care in Poeciliidae fish family (Pollux et al., 2014). It is thought that maternal care intensifies after post-fertilization, which adds to fetal-maternal conflict (Pollux et al., 2014). This as a…

    Forces Of Evolution

    • 479 Words
    • 2 Pages

    The four forces of evolution is natural selection, genetic drift, gene flow, and mutation. To start of, natural selection is when organism adapt to their environment and the animals that can't eventually die off. For instance their were other species of cheetahs but the ones that are alive now were selected from natural selection because they were the strongest and the ones that could reproduce more. Genetic drift is a change in a species that might or might not exists in the future. For…

    Evolution Of Fish

    • 1126 Words
    • 5 Pages

    your great-great-great (multiply by a billion) grandmother was a small, humble fish of the Devonian age. The fossil history of amphibians provide evidence of the first tetrapods: now-extinct amphibian species going back nearly 400 million years. Evolution of tetrapods from fishes represented a significant change in body plan from one suited to organisms that respired and swam in water, to organisms that breathed air and moved onto land. These…

    Evolution is taught within elementary schools and in high school biology classes, but religion is not taught in the classroom setting. The concept of teaching evolution and religion in schools has been brought to the courtroom a numerous amount of times. Epperson vs. Arkansas in 1968 was one of the first cases to go to court. Epperson argued that by not teaching religion and only teaching the theory of evolution we are limiting the students understand of…

    The subject of evolution is widely debated topic. However there is a wide variety of evidence that supports evolution. By studying the fossil record, comparative anatomy, genetics and natural selection scientists have been able to support Charles Darwin’s theory (evolution). This report will focus on evidence from the fossil record as well as genetics. The fossil record is the collection of information that shows the occurrence and evolution of living organisms through geological time from…

    Evolution Vs. Creationism

    • 715 Words
    • 3 Pages

    Evolution versus Creationism has been a controversial issue for many years, and still is. Conflicts between evolution and creationism occur when evolutionists argue that creationism is not a scientific theory because it cannot be tested by the scientific method, whereas creationists argue that evolutionists do not take God into account and that evolution is just a theory rather than a fact. Both sides have convincing arguments and good reasons why the other side's opinion is not correct, but…

    Eukaryote Cell Evolution

    • 300 Words
    • 2 Pages

    Evolution appears directional if we view the fossil record’s progress from simple unicellular creatures to multicellular ones, then invertebrates, dinosaurs, mammals and humans. This is supported by certain biologist’s who argue evolution favours the directional development of complex life . However, life is not a straightforward progression towards complexity. Natural selection can’t explain revolutionary change because while species produce evolutionary trends through their adaptive…

    Evolution is how modern living organisms are related to ancient ones. Organisms have diversified and modified through ages and old one became extinct. According to Charles Darwin, all species have common ancestors. This means that, for instance, whales and dogs are related to each other by an old ancestor. Indeed, many organisms have common traits and characteristics, but this still doesn't mean that they are related. Darwin's theory, which all organisms descend from one ancestor, is the result…

    love Jesus and Accept Evolution. Evolution is the theory that animals evolved into different species over time. A lot of times people who believe in evolution are not Christians, but there are some Christians who do believe that you can be a Christian and still believe in evolution. This is a controversy because some people believe that if you are a Christian, you cannot believe in evolution. I however am a Christian, and from reading his book and learning more about evolution, I agree with…

    The Darwinian theory of evolution, that is, all beings grew and transformed from simpler to more complex beings over time, is taught in public schools nationwide. This theory and none other are taught to children in public schools even though other theories are also widely believed and have both similarities and differences in the evolution theory. Why, then if there are other evolutionary theories, is just this singular theory taught instead of them all being taught? If no one theory can be…
