    1. In order to compare different spiral galaxies, a secure sample of spirals must first be defined. The sample is defined by selecting galaxies with pfeatures × pnotedge-on × pspiral > 0.5. A further cut is also imposed where only galaxies with Nspiral−Ncan′ttell≥5Nspiral−Ncan′ttell≥5N_\mathrm{spiral} - N_\mathrm{can^{\prime }t \, tell} \ge 5 are selected, meaning that at least five people classified the spiral arm number of each of the spiral galaxies, reducing the effects of noise due to low numbers of classifications

    1. A future in which parents select meaningful aspects of their childrens genetics engenders anxiety in many people, despite the fact that our selection of a mate has always included such reckonings. Perhaps the use of technology for this purpose seems too controlled and calculated. To see why even people with no strong religious objections to advanced germinal choice technology might want to prevent it, imagine the following best-case scenario: Medical geneticists learn how to substantially reduce our vulnerabilities, improve our health, extend our vitality and lifespan, and enhance various other human attributes. Complications turn out to be modest and manageable. Public opposition, strong at first, soon withers into insignificance. Parents are thoughtful about the choices they make for their future children. The technology is sufficiently simple and inexpensive to be widely available. Totalitarian regimes don’t try to impose it on their populations.

      Along with these issues is one that has sparked controversy in other areas of genetic engineering - lack of genetic diversity. Without genetic diversity, any species of animal or plants runs the risk of being eliminated whereas a species with plenty of genetic diversity allows room for flexibility. If in the future parents have the ability to choose their child's genetic makeup, It is very likely that certain traits, qualities, and characteristics will become more popular than others. Certain types of traits will be passes on from generation to generation and the genetic variation of our human kind could become at risk. Granted, it is far-fetched, however, it is a possibility and the idea of a "perfect" human species, one free from mother nature's flaws, might just be the complete opposite.

    2. Because cellular fluid, called cytoplasm, contains about a dozen special genes that are inherited, the committee even recommended banning cytoplasmic transfers into the eggs of women suffering from a cellular disorder that would otherwise keep them from having children.

      One of the arguments against these types of procedures, as well as other genetic modifications, such as cloning of animals and even genetically modified food, its that the process of manipulating the genetic variability of an animal/species and the artificial creation of a new being, or mind in the case of animal cloning, is unethical and should not be allowed. However, one could make the argument that, in this specific case, depriving women the opportunity to treat them and preventing them from potentially having to deal with such a disorder is perhaps even more unethical then the treatment itself.

    1. Physis, also, the arising of something from out of itself, is a bringing-forth, poiēsis. Physis is indeed poiēsis in the highest sense. For what presences by means of physis has the irruption to bringing-forth, e.g. , the bursting of a blossom into bloom, in itself (en heautōi).

      Just as a the blossom turns into a bloom, the primitive ape of nature become man as we know it today. The evolution of human intelligence can be used as an example of Physis.

    2. One says: Technology is a means to an end. The other says: Technology is a human activity. The two definitions of technology belong together. For to posit ends and procure and utilize the means to them is a human activity.

      Technology is something that humans need and quite frankly would not exist without. It is what makes us the dominant species we are. Humans need technology to survive. We utilize it everyday and, like Heidegger said, it 'is a human activity'. I would venture to go one step further and say that technology makes us human; our intelligence and our ability to improvise and create and innovate is what distinguishes us from the rest of nature. Heidegger's second "definition" of technology is that it is a means to an end. Not only is it a means to an end but it has almost become a requirement of our species. We are constantly creating and improvising much further past the ends we wish to satisfy. These two statements defines technology and not only establishes it as a human activity, but i would venture to say that technology has become a defining characteristic of humans today; it has become something that is intrinsically human.

    1. Water Conquest

      In this scene, as well as the scenes involving the leopard, hog, and aggression towards the bones of the dead animal, conflict seems to be a main theme; there is always a conflict between two different groups or beings trying to compete. In the example of the leopard attacking the ape, the leopard is competing for food - either the ape wins and eats the leopard and gets to survive or the leopard wins and earns itself dinner and the leopard gets to survive. Or in the scene where the apes with their new technology (bone clubs) take over the watering hole, the two different groups of apes are competing for a resource - water. It would appear that no matter what aspect of the first few scenes you analyze, man, nature, or technology, competition seems to be involved with them all.
