    What is an invasive species? According to the National Invasive Species Management Plan, an invasive species is defined as “a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health”. Invasive species will look like they belong in the environment they are taking over, however, more than likely they are over-powering a native species in their own habitat. Would you be able to identify one of the species I’m about to discuss? North America has more than twenty-nine hundred invasive species in our environment today. I will begin by describing 2 invasive plants and then 2 invasive animals that are invading our natural species. First we have the invasive grass called “Cheatgrass”, which is scientifically known as Bromus Tectorum L. Cheatgrass was introduced into the…

    To what extent are Humans a Unique Species? We like to believe that humans are a superior species, highly intelligent and beyond the realms of the animal kingdom, however, are we really as unique as we like to think, what makes us so special? It was once believed that humans were the only animals capable of using tools, and this is what made us no longer just ‘animals’. In the 1960s when chimpanzees were first observed using twigs to retrieve termites from wooden trunks, as a form of tool, it…

    Prompt 1 One of the greatest and most renowned biologists of all time, Charles Darwin, wrote a fantastic novel The Origin of Species. The Origin of Species begins with an extraordinary image of existence as coexistence. Darwin describes this through the process of how multiple beings rely on each other for survival. Morton describes this as, “Water and air are like hair and feathers. Living and nonliving beings become the medium in which other beings exist.” (Morton 61) He also goes on to say,…

    been the dominant invasive species on the planet. As they have increased in population, their habitats have invaded the habitats of many native species. As natural habitat decreases, one of two outcomes can occur for the invaded species. One, the extinction of the species in the invaded region, or their evolution of “domestication.” This domestication, or human commensalism, develops as a species continues to breed in a human-occupied territory (Brown et al. 2013). For insects requiring a…

    Invasive species are easily comparable to the explorers of the old days. Explorers could be helpful by introducing new supplies, like horses, during the big Columbian Exchange. Explorers could also be largely negative, bringing disease and slavery into the nations they conquered. Explorers sometimes just set up trade relations and left well enough alone. Much like these explorers, invasive species have the propensity to help, hurt, or assimilate into their new surroundings. Experts on invasive…

    This book describes the theory of evolution as “the central unifying principle in biology.” While the idea of evolution had appeared before Darwin’s time (by others including Darwin’s grandfather, Erasmus Darwin) it is in November 1859 that Charles Darwin formally presents his idea in On the Origin of Species. What makes this work so important is not just the idea of evolution, but that Darwin provides the key mechanism, natural selection, for evolution. Through natural selection, species with…

    evolution of biological species this is according to the Sage’s English dictionary and thesaurus. It is the continuous change in the genes of an existing specie until a formation of the new specie arise altogether. It is a result of two specie groups ceasing to share allele such that the genetic differences grow to the point of speciation. Many scientists have come up with different theories in an attempt to define and explain speciation, though different they all agree that for an organism to…
