Are Humans Still Evolving Essay

Medicine became the new normal in the 1800`s which produced new people who invented things, new ideas , new outlets of inventions and a discovery of new medicine which benefits us to this day . Many of the scientist I mentioned played a role in all these changes.Which today we need to learn to appreciate.I believe if some of these things didn 't happen we wouldn 't be as healthy and appreciative.Also I don 't believe doctors would know what they were doing to cure people.The different medicines in society to this day were because of many years ago.Furthermore we don 't even recognize the value of these scientist.

Survival of the Sickest is an intriguing novel that explores why we need disease. Moalem asks and answers many questions throughout this book centering on the concept of evolution. His main objective in this book was to explain why natural selection designated certain diseases that are harmful to humans now. Throughout his questioning, he shows us that the reason so many diseases are still around today is because at some point in history, all of them helped our ancestors to survive and reproduce in their environment. Each chapter in his book focuses on a different aspect of his overall conclusion that modern diseases were beneficial in the past. Each topic gave an example and new understanding of evolution.

Throughout all of history, medicine has been changing and making improvements. Many of these advancements came about during the 1920’s. Some of the greatest medical ideas, events, and inventions occurred during this time. Several great scientists and doctors discovered a myriad of new cures and technologies to correlate with the prevention of sickness and disease. The practice of medicine also has become more advanced and reliable.

Evolution is the process of change over time. It can be split in two questions, how did something living come from something that was not alive? And, how did things that were already living turn into other living things? Natural selection is when the “breeder: is the environment. This belief of natural selection came from Charles Darwin. Many ideas led him to believe what he believed. One of them was, James Hutton’s ideas about geological change. His theory consisted that sediments, rocks, soil, etc were made after the great flood and new species “rose” from that disaster and that it’s a cycle. Charles Lyell’s theory also shaped his thinking. Lyell wrote the book of “Principles of Geology”, where Hutton became famous. He believed that the earth

At the time not even the most straightforward diseases, for example,not even the common cold was curable. Until the best medicinal disclosure at the time was accidently found in 1928. Starting its potential amid World War 2, the entire world needed its hands on it. It was Penicillin. Penicillin left an imprint in our history, it expanded medicinal innovation, manufacturing and even diminished diseases. it increased medical technology, manufacturing and even decreased infections.

Medicine has changed over the centuries. At the beginning of the history of medicine, people believe that diseases was a symptom of imbalance in the body as a result of actions of an external agent, such as bad air or demons. Greek and Egyptian believe that diseases come from Gods as a way of punishment of bad behavior. But through the years this idea medicine began to change. People start to study human body and their anatomy to discover and cure of illness.

This important documentary does not come close to doing justice to Gawande 's video: Being Mortal. The book is rich with excellent examples of doctors, nurses and family members doing their level best assisting others to live the fullest and richest lives possible right up until and including the very end of their lives. As Dr. Atul Gawande would say, the point isn 't to strive for a good death but rather to have the best possible life that is congruent with one 's own values; and to make medical decisions and choices accordingly. By living each day in harmony with one 's goals and values, one is likely to have a good death. Modern medical advances have lengthened the human life span, such that it is now longer than it has been at any point in human history. These advances happened alongside the

In 1932, Aldous Huxley imagined and wrote about a world where designer baby technology is prevalent in his science-fiction novel, Brave New World. The technology would not come until many years later, but his ideas still hold up today. In the book, there were different classes depending on how genetically modified one was, including Alpha or Beta (“The Public Should Oppose Designer Baby Technology”). Outside of science fiction, though, is real science where an actual baby can be genetically modified before even being born. A designed baby is one that is purposefully shaped to be one way or another through processes including In Vitro Fertilization (IVF), where an egg is fertilized and genetically altered, and preimplantation genetic diagnosis

Natural selection is an important component of evolution. It occurs when some members of a population are better fit for survival and proliferation than others in that population. The environment in which organisms live plays a large part in natural selection as well. Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer ["Natural Selection and Speciation - Biology."].

In today’s world, you can have your baby with blue eyes, perfect height, and how you want your baby to look when is old. Now we can even make a baby be born smart because now scientists are more specialized in genetic and how the genes work. For example, if women can’t have babies she can rent a belly from another woman so she can have the baby but the baby is going to have the DNA of the women who can’t have babies, not of the other woman. Is pretty impressive how today scientist can modify genetically the genes of babies before they are even born. Now in today’s world is almost possible to create the perfect baby if we want. It is impressive that this idea originated from a period of time where there was little knowledge about genes.

Additionally, the book modified my judgments of inheritance. Many research topics can stem out of these inherited defects with beneficial advantages for survival such as taking a part of the G6PD- deficiency gene to cure malaria. Furthermore, studying defects like hemochromatosis, diabetes, or favism may be crucial to taking a leap (and hopefully, landing) in the scientific and medical community. And we end on this quote from Dr. Sharon Moalem himself which very accurately sums up my comprehension of evolution from this book, “If you’ve come this far on our journey across the evolutionary landscape, you’ve probably gathered a good sense of the interconnectedness of — well, just about everything. Out genetic makeup has been adapting in response to where we live and what the weather’s like. The food we eat has evolved to cope with the organisms that eat it, and we’ve evolved to cope with that. We’ve looked at the way we’ve evolved to resist or manage the threat posed by specific infectious diseases, like malaria… At the end of the day, every living thing — bacteria, protozoa, lions, tigers, bears, and your baby brother- shares two hardwired imperatives: Survive.

Darwin was a firm believer in evolution and natural selection, and he wrote many works which provided evidence of his hypothesis. His main point was that as a species, including humans, continues to evolve, natural selection chooses the best traits to be inherited to the next generation. However, natural selection does not only affect physical traits but, “applies no less to intellectual and moral powers than to physical traits.” (Darwin 64)

As Darwin would describe the hominid transition, us humans were better fit to survive and reproduce on Earth’s landscape. Our superiority drove the Neanderthals to extinction. An article published in Science compares the 4 billion nucleotide DNA sequence of the Neanderthals to modern day humans. The researchers identify a number of genomic regions that may have been affected by positive selection, including genes involved in metabolism and in cognitive and skeletal development. Genetic sequencing studies support this claim as well. According to Recent and Ongoing Selection in the Human Genome published in the National Center for Biotechnology Information, the human genome appears to be targeted by selection. The researchers estimate that at least 38% of all new amino-acid altering mutations in the human genome are being eliminated by negative selection. As Homo sapiens outlived Homo neanderthalensis, it is a plausible conclusion that genetically humans are more adapted to Earth’s

As the penman predicted, the mankind is now in the process of putting on the analogous paradigm to the control of mother nature (Mazzoni). Literally speaking, people are now engineering nature. They try to create and produce new forms of life by making interventions on the microcosmic level. With genetic modification, people climb to a new, highest level of genetics. The cloning industry as well as genetic engineering are advancing so fast that it would only take a short time until people would feel the power and would misuse them on their own account (Schumacher). One day cloning human beings will be an ordinary procedure just like in the novel by Aldous Huxley.

I want you to stop for your second and look at the person sitting next to you. What you are looking at is the fine result of over 200 thousand years of evolution; the master piece of natural selection, and a perfectly adapted organism to life on earth.
