In chapter 3 of “Why Evolution Is True” by Jerry A. Coyne, he talks about remnants such as vestiges, embryos, and a bad design in which he describes manuscripts called palimpsests organisms of evolutionary history. In evolution, a feature of a specie that was an adaptation in its ancestor but lost its usefulness are called vestiges. These no longer perform the function from when they first evolved because those parts may have been import to their ancestors but not to them. The author states, “In…

Natural selection is very important in the addition of adaptations to bring forth more able and stronger individuals that can survive in their harsh environment. Selection can make some organisms deadlier, like the Asian giant hornet, or can make other organisms better at finding food in hard to reach areas, such as woodpeckers with thicker skulls. Each of these adaptations are unique to these organisms because these adaptations allow them to live in their unique niches. For natural selection to…

Critics have argued that new technologies such as DNA testing allow for the potential development of new forms of eugenics. What might these forms include? What are the potential dangers involved with these new technologies? It is undeniable that any method that intends to maintain the “good genes” in society would not only spark an extended array of ethical concerns but could also backfire in several ways. Human genetics has been the topic of several debates for an extended period of time,…

In some populations, alleles can be lost due to random events. Genetic drift reduces allele frequencies in smaller population, therefore, decrease genetic variation. It can eliminate alleles at a faster rate in smaller population until they become fixed in the population. On the other hand, alleles in a large population rarely become fixed by genetic drift. This indicates that genetic drift has a greater effect on a smaller population by getting rid of alleles at a faster rate. Genetic variation…

Nature versus Nurture can be defined in many different ways with many examples. Nature is the “genetic influence” of a person meaning someone’s hair, or eyes, and more. (56) Nurture is the “environmental influence” on a person meaning how the outside world can affects someone’s development. (56) For example, many adults struggle with alcoholism which means they always feel the need to drink alcohol. An adult suffering with alcoholism could alter how their child sees the world. Being the daughter…

Evolution is a frequently debated topic in the science field. The theory of evolution helps us to understand how organisms on Earth have changed over time. Richard E. Lenski, author of Evolution: Fact and Theory, emphasizes that although evolution is a theory, scientists have discovered a great deal of evidence for evolution. DNA and genetics are the foundation of all life. All organisms contain DNA from their parents and no two organisms have the same genes. Our genetics…

Developmental Influences and Considerations Life’s circumstances vary from one person to the next. It can be assured that none of us are born for the purpose of becoming addicted to substances, habits or some other demoralizing infatuation. However, life’s experiences are often both good and bad teachers; paving the way for the possibility of debilitating problems which may not be so easily conquered. In the case of Alan, we are offered an idea of how troubles in life can send someone to the…

When Charles Darwin published his work on natural selection, he suggested how absolutely important the ability to adapt is in the natural world. However, the concepts of adaptation and evolution apply to more than survival of the fittest in the natural world and, in fact, hold true in business as well. Founded in the 1930s, the Old Spice company produces hygiene products for men and women, with their original focus being on shaving soap and aftershave lotion (“History of Old Spice,” n.d.). An…

An autopsy is done to gather evidence of a cadaver in an investigation to know the cause and time of death. The individual administering the autopsy is known as the pathologist who is a medical doctor that determines the time, cause, and means of a crime. The pathologist will determine if a weapon was used to kill the victim, whether the victim lived after the injury, evidence of a struggle self-defense or rape/sex related crimes. Algor mortis is one of the three mortises calculates the average…
