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…

Gynecomastia’s history/discovery, the effects, & the present/future ideas are important information that are relayed in…

Byron Likdisha AP Biology Essay #2 The modern synthesis incorporated Charles Darwin’s theory of natural selection and many other fields of science, including genetics, to explain evolution more accurately. When Darwin wrote “On the Origin of Species “, he only explained the first mechanism of evolution, which was natural selection. The modern theory of evolution now highlights three more important mechanisms for evolution, which are mutations, genetic drift, and gene flow. Many…

in the classroom and while shadowing a physician. While these two types of learning are very different, they both are vital aspects of having a holistic education in the biological sciences. Through my major in Cell Biology and Neuroscience, I have also been able to build on my biology foundation by delving more deeply into neuroscience, the facet of the life sciences that most interests me. I also have had hands-on experience working at the cellular level in my laboratory and have developed a…

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…

Charles Darwin and Alfred Wallace came to the same conclusion on the study of Evolution and created the Theory of Evolution based off Charles Darwin’s book Origins of Species. Through gathering of support and evidence for his suggestion, at the age of 50 in 1859, Darwin finally published his theory of evolution with the help from Alfred Wallace. Wallace contributed into developing the theory of evolution supporting what Darwin had created. In fact, when the two compared work, the study from…
