Evolutionary developmental biology

The little things that allow for differentiation between twins and siblings fall to individual genes that play the role of personalization in humans and result in unique coloring or patterning in animals. While this is taking place on the micro level the macro evolutionary changes are being handled by HOX genes the master organizers themselves. On the macro level changes to the body plan are being made. This is of course not to say that micro and macro evolution work in anything but tandem to keep the multiple developmental processes…

Galapagos is a science fiction-fantasy story set in a third person narrative that was written by the author Kurt Vonnegut. Most of the story is set in the hotel of El Dorado in Ecuador and is spent introducing the characters of the story. The main characters are Mary Hepburn a widow from America who was a biology teacher at Ilium High School recently laid off from her job and mourning the death of her late husband Roy Hepburn who died of a brain tumor that slowly robbed him of his judgment and…

tomato, tiger, etc.…That common ancestor produced descendants, and those descendants produced their own descendants and modification takes place for each generation of descendant eventually leading to the wide variety of Earth’s lifeforms we have today. Common descent with modification occurs due to mechanisms of evolutionary change. A mechanism of evolutionary change requires for the process to affect the allele, gene variant, frequency. Natural selection is one of these mechanisms. The process…

infrastructure that the country, will be in the future with the equivalent of dozens of hurricane Katrina (Kozol, 2008). For over twenty years, Americans sought inspiration in the Asian model of development. It is time to take a second look. For all memes are the characteristics of any process of evolution: fertility (some ideas are particularly effective), longevity (persist for a long time) and replication fidelity (traditional conservatism, especially taught as part of early childhood…

In the essay, “Evolution as Fact and Theory,” Stephen Gould defenses Charles Darwin’s theory of Evolution over the beliefs of creationist on God creating all organisms in the world. To further his support, he states his three arguments which are observational evidence, the imperfection of nature, and transitions found in fossil records to demonstrate that even though evolution is just a theory, there are plentiful evidence of facts that supports it. The essay was not just about justifying the…

We humans are inquisitive by nature, it is in fact what sets us apart from other animals on this planet. Since our exodus from the African continent we have always wanted to know what was beyond that hill, our desire to learn as much as possible has allowed us to make advancements in technology and create civilizations. But this desire to learn had also extended to the machinations of nature, and in response we created religions as an explanation to the creation of the universe. Religion was…

order for natural selection to occur the parents of the offspring must have important inheritable traits that would allow them to thrive in whatever conditions that surrounded them. It is simply comparative advantage for some species to be stronger and more adept and efficient than others. If there is a specific and large change within an environment that hosts a living being, then adaption is more likely to occur. For instance, during the Industrial Revolution, soot and waste darkened the tree…

inquiry, the concept of paradigm provides parallels in disciplines beyond scientific research that spark debate. “Successive paradigms tell us different things about the population of the universe and about that population’s behavior (Kuhn 2012, 103).” Paradigms of science offer explanations of natural phenomena, whereas paradigms of the humanities and social sciences prescribe human behaviors Taking an interdisciplinary approach, the paradigm theory extends towards sociobiology.…

Almost each of us reaches a moment where we wonder how the earth was created –or was it really created? We also once asked ourselves, “Where did humans come from?” or “How did humanity come into existence?”All this time we are so curious about such things. All this time we ask ourselves different questions that remain unanswered. There are two different ways on how we are going to answer all the questions we created in our mind. There are two different ways on how are we going to explain the…

or a supreme being created the human race rather than evolution. However, the belief against evolution strongly differs by religious group. Protestant followers believe humans have existed in their modern form since the beginning of time. While people belonging to the Catholic community suppose humans have evolved through times but were created by God. Each of the opposing sides whose argument is based on religion is opposing the foundation of what the United States was created with: the freedom…
