Most of us think about evolution in some prehistoric sense. After all, we were first exposed to the theory of evolution in elementary school studying about dinosaurs. But evolution has not stood still; it has been an on-going process. There are many contributing factors to micro and macroevolution. Microevolution therefore refers to changes in DNA within a population for adaptation. Scientists have uncovered a gene BMP4, which shapes the beaks in Galapagos Finches. According to Weiner the finches

Evolution, a well debated topic, a theory that’s been around for centuries. A theory, evolution as an example, is an idea that is there to explain or prove something. Evolution is a process where different species and types of organisms have developed, slowly breaking away from one another over time, changing, growing, gradually changing overtime, developing into the organisms we have today. Any theory needs evidence to support it, evolution happens to have lots of evidence to support it, such as

This case study takes a look at a kid named Jim, who developed a long-term mental disorder called Schizophrenia. Although the precise cause of schizophrenia is not known, certain factors seem to increase the risk of developing the disorder. In Jim’s case, there are many factors that put him at risk for developing schizophrenia. Of the few, the most important factors are the old age of his father, the history of mental disorder in his mother, the mental stress Jim experienced as a result of his father’s

Throughout history, Animal Experimentation has played an important role in leading to human discoveries. However, with new technology, Animal Experimentation has become obsolete. Nevertheless, experimentalists and companies still choose to test their products on animals in order to prove that the product is safe for their consumers, which is mainly made up of humans. Because companies still choose this method over others, animals from breeders and shelters are subjected to torture and bad living

Jerome Kagan once said, “Genes and family may determine the foundation of the house, but time and place determine its form.” This quote recognizes that nature and nurture both have roles in determining why people are who they are. Nurture explains that people are the way they are based on how society and their environment has shaped them. On the other side, nature states that people are defined based on genes handed down to them. Both explanations hold some truth; however, some people believe

Before the use of lifespan development psychology (which studies changes that take place during each period of life) development studies were mostly done during childhood. Similarly it is generally believed that motives acquired in early childhood stay stable throughout adulthood, but studies have shown that there are age-related changes during a lifetime.”Do we seek the same fundamental things-love, power, achievment-with the same intensity throughout our whole lives? Or in other words, are implicit

When asked what I am most curious about, the first thing that enters my mind is genetic engineering. I would like to know more about how this technology began and what its original purpose was. Also, I long to discover how this technology is being expanded, what purpose it is it being aimed towards, and how it is due to develop in the near future. I have read that Francis Bacon was the first scientist to allude to the future field of genetic engineering and terminator technology. Although terminator

Why are the same animal species so different from one continent to another? That is a question that Charles Darwin asked himself. Charles Darwin was an English naturalist who studied evolution through animals during a five-year expedition around the world in the 19th century. He explained all his discoveries and investigations in 1859 in a book named “On the Origins of Species” and he also published in the same year his Theory of Evolution by Natural Selection. Some of the animals that Darwin observed

The Great Danger of Genetic Modification in Human Beings. According to Ronald Greene in ‘Building Baby from the Genes Up’, “National Institute of Health has come up with a program to build machines with the ability to detect genetic letters in human’s genome.” (Greene, 496) The researchers believe that this will lead to being able to see DNA sequences which could later result in a particular disease or illness in a person. According to Ronald Greene in ‘Building Baby from the Genes Up’, “National

Nature vs Nurture Both nature and nurture play roles in the development of a child. That’s because children inherit genes and traits from their parents, sometimes children end up with more traits and genes from either parent. Some traits passed down may not have shown in the adult but show in the child that was born. There are a lot of roles that nature play in the development of a child just like there are a lot of roles that nurture play in the development of a child. You really cannot separate
