Evolutionary biology has always interested me, specifically the mechanisms of natural selection and how species adapt to their environment. It started with my love for animals and nature when I was little. I spent my summers working with horses at a local corral, where I would ride around the surrounding wilderness areas. My favorite part about riding in the mountains was watching the change in plant and animal species as the elevation changed. It never ceased to amaze me how the alpine tree line was always so sudden. Humongous pine trees would give way to the short, shrubby plants of the alpine tundra so uniformly and noticeably. I have always wondered about the environmental conditions that cause species to distribute themselves in …show more content…
Whether it is through competition, symbiotic relationships, pollinator dynamics or the millions of other interactions that occur in nature, species have evolved together and thus live in certain niches or behave in certain ways in order to survive. When I was younger I always thought of these observations as just the way things had to be in order for nature to work, but now I realize these relationships are key to understanding how the natural world has evolved due to environmental conditions. Furthermore, the understanding of the mechanisms behind these natural phenomena are important in developing solutions to the current mass extinctions and decline of species. The biodiversity I observed as a child in the mountains and the biodiversity that I am studying now in college is one of the subjects I find to be most intriguing and important about evolutionary biology. The ways in which species evolve through natural selection and thus differentiate how they behave, look, or live is what contributes to the natural beauty and interconnected interactions of nature that first made me love animals and the outdoors. The mechanisms of evolutionary biology keep me inspired to learn about the natural world in order to determine how I can help preserve it. This has led to my aspirations of going to graduate school in wildlife biology and pursuing a career in research to solve current issues in wildlife
But natural selection is not random Another confusing argument you may hear from a pro-evolutionist is the idea that evolution is in fact not random, and is not due to chance. They argue that evolution through natural selection is actually not chance at all. The reason being is that natural selection is in simple terms, survival of the fittest. It is logical.
Biology plays a part in every single aspect of what is going on in the world, both on land and in the water. Natural selection is a huge deal in biology and is the process where organisms better adapt to their environment to better survive and reproduce. Evolution by natural selection has been going on forever now and it is impressive just to what extent a species is capable of evolving. An article that greatly explains how amazing the ability to adapt is called, “Against the Tide: A Fish Adapts Quickly to Lethal Levels of Pollution.”
Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical
At the age of 11, my family and I visited The Museum of Natural History in New
Through this, I have learned about evolution. I find it shocking that one DNA sequence is what differentiates certain species from others. I have learned about switches, which takes a big role in the makeup of organisms and its diversity. Between Darwin’s knowledge and today’s knowledge, I am beginning to make connections about
Darwin: Well in that case I suppose that it could affect natural selection in that if a food source or necessity is changed that it could encourage recessive phenotypes but overall the ones best suited for the environment would be able to survive.
Understanding good design requires addressing the question of what units undergo natural selection, thereby becoming adapted (Shelton, 2014). There is a natural connection between the formal Darwinism project (which aims to connect population genetics with the evolution of design and fitness) and levels of selection issues, such as natural selection acting on individuals, or on populations (Shelton, 2014). Darwin offers contradictory ideas of thinking concerning these levels of selection (Shelton, 2014).
Survival of the fit(-test) ties together with Darwin’s theory of natural selection. All species evolve, as it is usually the only way to survive. Some species evolve to better themselves, such as the sea slug, who steals genes from its food (i.e. algae genes would allow it to live off of sunlight for a few days). Other species evolve to survive and get more food, such as Galapagos finches, who evolved to have smaller beaks to eat smaller seeds (this is because larger birds with larger beaks ate all of the bigger seeds, thus causing an evolution). Different species evolved to protect themselves, such as blue mussels, who thicken their shells when predators come close (mostly Asian
Evolutionary thought and research has come a long way in the last few decades. While several factors have been identified as contributing to species evolution (Huxley 1942), natural selection is widely accepted as the main and strongest evolutionary force. However, Gould and Lewontin (1979: 581-598) argue there is a danger in trying to explain all evolution using an adaptationist programme where selection is the go to answer, even to the exclusion of other possibilities
Background Despite having studied a range of scientific topics, I have developed a strong interest in biology over the course of my studies to date, particularly ecology and evolutionary biology. This interest began as a result of engrossing palaeontology modules I participated in during the last two years of my undergraduate degree, which covered the history of life from its earliest forms over half a billion years ago right up to the modern era. This study of the change of life over vast scales of time proved fascinating. In addition, the zoology module I was taking at the same time covered the biological aspects of evolution (as opposed to the palaeontology module's geological focus), which strengthened my interest. Although I specialised in earth science during my undergraduate, I took some years out to consider my future plans, which led to my return to university to pursue a Master’s degree in evolutionary biology.
. In my own words when I think of natural selection I think that it means that the fittest survive. Also that when the fitness survive they are automatically given the opportunity to keep their genes going. This process of the weak dying off and the strong moving on is what makes everything living thing evolve into the best. The next force of evolution is genetic drift I think that this means that just sheer chance the weak genes actually move on and some strong genes do not move on. The third force of evolution is gene flow and I describe this force as a change in a group because of certain genes that came into their group from migration or immigration. The last force is mutation and I describe it as a change in the gene that results in different
A theory discovered by Charles Darwin, and released to the public in 1859, answered many questions for scientists who weren’t able to figure it out. Using the Theory of Natural Selection, he came up with the Theory of Evolution. In the Evolution theory, it states the genes that allow a species to thrive are passed down from parent to offspring and it also provides us with an insight of the changes an organism goes through over time, in which it relies on Natural Selection to do so. Despite doubters and opposers, there has been lots of evidence to prove it such as Biogeography, Biochemistry, relative dating, embryology, and homology. Biogeography refers to the distribution of plants and animals, while biochemistry refers to DNA similarity
The biological topic of my choice is human evolution and natural selection. These topics ties into our class lectures because we have talked about evolution and Lamarck's and Darwin's logic. Lamarck's logic was based on the inheritance of acquired characteristics. He believed that organisms characteristics were inherited during our lifetime. We discussed Lamarck's logic in class, and we learned that Lamarck was not completely right. We also learned that Darwin used variation in the organism's traits with features in their environments, and he believed that within a population there can be a slight different in appearance and function. This article interested me because the article explains how a slight different in nose shaped can have a different
Today many scientists are able to measure evolution through genetic mutations in plants and animals alike. Charles Darwin developed the Natural Selection Theory, stating that organisms that are best fit to adapt to their environment will thrive and produce more offspring thus passing on their thriving genes. This goes hand and hand mutations because for example, if a red fox lives in a snowy climate and produces an offspring with an albino mutation, the offspring with the mutation may be better able to survive due to the fact that the animal blends in better with the environment. Thus, surviving longer and producing more offspring with the same genes and ultimately evolving the species.
