Are people the way they are because of their genes (nature), or because of how they were brought up (nurture)? Multiple sources provide insight that points towards humans being nurtured as opposed to being nature. One source is Mary Shelley’s Frankenstein which is about Dr. Victor Frankenstein and how he creates a creature who is nurtured by society through multiple events. He obtains multiple traits throughout the story. The next source is “The Nature vs. Nurture Debate” which discusses both…

Name: Desire Salazar Date: 12/15/17 Period: Pre-AP Biology 5th Title: Population Genetics and Evolution Problem: How does the Hardy-Weinberg law provide evidence of evolution? Background Information: The lab will determine how the Hardy-Weinberg law provides evidence of evolution in a population. A population is “a group of organisms of one species that interbreed and live in the same place at the same time” (Biology Online). In each population, are three key elements: size, density, and…

Genetic drift is a mechanism of evolution that occurs by random chance rather than natural selection. In genetic drift, a population experiences a change in the frequency of a given allele, prompted by random luck rather than a need for adaptation. This differs from natural selection, in which allelic frequency is altered based on the fittest genes surviving to reproduce and the weaker genes dying off. Genetic drift tends to be a phenomenon amongst smaller populations, while natural selection…

Scientists classify organisms by grouping and sorting organisms together based on their physical structure, evolutionary relationships, embryonic similarities, genetic similarities, and their biochemical similarities. The most popular form of classification system used by scientists is Linnaeus’s System of Classification, by which organisms are classified and grouped into 6 different kingdoms; bacteria, archaea, protista, fungi, plant and animal. By classifying organisms it provides scientists…

Mutations are changes in the genetic code which is the only way through which new genetic material and variations can be obtained. Mutations further include chromosomal mutations which is necessary for various variations. Genetic Drift can be defined as how the changes that occur randomly in the frequency of alleles which impact populations of many species. These also lead to effects such as bottle neck and founders effect. Natural Selection revolves around the concept of fitness which…

New Take on Tropical Songbirds’ Alternative Lifestyles A breakthrough study published on Friday in the journal Science uses life history theory to explain why tropical songbirds typically raise fewer chicks than temperate songbirds. What’s life history theory? Life history theory seeks to explain the ways in which natural selection works to determine a given organism’s anatomy and behaviors. Life history theory suggests that reproductive tendencies, or “life history strategies,” are part of a…

I successfully completed an honors thesis through the Biology Honors Program, and graduated with distinction in research. I wish to study social behaviors in an avian system, with a particular interest in behaviors relating to courtship and breeding. My research experiences have reinforced my dedication to earning my PhD and conducting research in animal behavior. I have worked on research projects spanning topics from social structures to courtship behavior and migration, and I have found my…

All animals belong to the supergroup Unikonta. Since these animals are found in almost every environment on earth, it has become possible to study their characteristics and construct evolutionary relationships, noting morphological and molecular similarities and differences. The relationships between the most primitive of animals were determined by the morphological traits of symmetry, tissues, body cavity, embryological development, and molecular evidence. [1] Symmetry and tissues are major…

Adaption is a change in gene frequencies as a result of natural selection (Wilreker, 2016). An adaption will manifest itself as a characteristic of an organism that is some way contributes to the organisms reproductive success (Wilreker, 2016). Bipedalism is an adaption of upright, two-legged movement rather than four-legged movement, and the key characteristic which makes early hominins different from the apes (Kottak, 2015). There are many advantages of bipedalism adaption which Scientists…

them. Monkey to man, or men with monkey brains? These scientists are no better than politicians, always lying and giving misinformation. Even if evolution may teach kids about human biology and life, doesn’t mean we can’t take evolution out without keeping those important things in. Evolution isn’t the key to biology, science…
