Evolutionary developmental biology

natural selection has not yet had a chance to deal with them. Lastly, the body may fall victim to certain tradeoffs between a trait’s benefits and its costs. Through evolutionary biology, the focus on understanding why things happen instead of how they happen can help us to prevent certain things from happening. Neglecting evolutionary biology would create a danger to public health due by failing to understand certain contagious ailments and diseases, like Ebola. In most instances Ebola is…

adaptationist programme is a narrow view of evolution and should be expanded to incorporate other explanations. They claim that one of the key adaptationist arguments is “if one adaptive program fails, try another” (Gould & Lewontin 586). In this way, evolutionary biology focuses exclusively on researching and publishing material on adaptation. They propose that scientists should instead explore other avenues of discovery that may lead to alternative explanations, explanations that they…

Embryonic Stem Cell research (ESCR) evokes immediate controversy because of its intimate connection with human biomaterials. Ethical concerns for this type of research involve human dignity, personal privacy, and autonomy (Knapp). The Stanford Encyclopedia of Philosophy argues that there is a dilemma between the duties to alleviate human suffering and the preservation of potential life. While it is true that research on embryos involved in research become destroyed, the potential therapeutic use…

Have you ever imagined the world with an identical copy of you? If you have you know it can be a terrifying thought. Duplicating ones – self would be walking in a world of no individuality. The world would lack diversity if nobody ever had the chance to be unique. Scientists are fascinated with the idea of cloning. You may ask, what is cloning? Cloning is the production of an organism with genetic material identical to that of another organism (Seidel 1).One’s physical character and behavioral…

Abortion has been one of the main topics in America to produce a plethora of controversy, marking the collision of two values: pro-life and pro-choice. While we know that each side produces a wide variety of points as to why each group believes what they do, we still must be omniscient about the life of the child. Someone who is pro-choice would argue that the woman has the right to her own body and what happens to it; however, taking the side of pro-choice disregards the child’s life. This…

As you wake up and hear the familiar cadence of the alarm, dread seeps into your deepest pores. Knowing you will suffer from intensified pain and less mobility than the previous day, you cringe at the harsh reality of your newly diagnosed condition. Yet the hope for a possible cure teases you daily, appearing more appetizing as each miserable moment passes. The desire to relieve your body from pain for even one day, no matter what the unknown the risks and long-term problems may be, is…

“Stem cell research can revolutionize medicine, more than anything since antibiotics.” This statement was said by former president of the United States of America, Ronald Reagan. Mr. Reagan in this statement was saying that stem cells are the future of medicine and can change how the medical field may approach a problem. Stem cells are cells that have the potential to develop into different kinds of cells. Stem cells have an internal repair system. They can also replenish other cells. There are…

avoid contamination must be followed. Further, the data collected for table 1 was made by approximating the developmental stage of the chick embryos instead of using the Hamburger and Hamilton table, this left us with data that was unreliable and we were unable to use because the factors we used to data the chicks such as size, are largely impacted by genetics and not good markers for developmental staging. We would need to repeat this experiment and use a larger sample size in order to…

Embryonic stem cells are very controversial in the scientific community and as well as the medical community for many reasons. “Stem cells are cells that can be any cell that the human body needs to be”,(Rowlery,usnews.com). For example, a stem cell can be a skin cell, a liver cell and or a bone cell. The reason why embryonic stem cells are extremely controversies is because the cells come from human embryos. To obtain theses types of cells a mother need to have an abortion, and doctors and…

The operations of cloning have brought out an abundance of fundamental milestones laying concrete on rearing onto the likelihood for an acceptance of therapeutic cloning. There exists a manifold quantity for the, “applications of this technology in nonhuman animal models will undoubtedly contribute in a major way to vaccine development and the unraveling of teratological and genetic problems in human development as well as impacting wildlife conservation efforts” (Wolf, Meng, Ely, & Stouffer,…
