Capstone Paper On Evolution

Evolution is a change in the characteristic of living organism through time. Modern synthesis, one of the greatest intellectual achievements of biology, could explain how mutations and natural selection could produced large-scale evolutionary change. There are 4 mechanisms for evolution to occur; mutation, gene flow, genetic drift and natural selection.
Although, there are a number of misconceptions about evolution; it does not explain the origins of life, it is not progressive, natural selection is not about the survival of the fittest individuals in a population, humans are not currently evolving, it does not make organism better designed nor does it gives organism what they need to survive. This essay will describe further, 3 common misconceptions

I have always found human evolution very fascinating. I think it is incredible how we have evolved from caveman to complex modern-day humans. The fact that such an enormous change did not occur overnight, but through a slow process that took place over hundreds of thousands of years, gives me the urge to continue researching. I am curious about how we have evolved dramatically in terms of appearance, characteristics, lifestyle, and many other aspects. Not only are these adaptations interesting, they are also essential to our entire existence. Without evolution, humans would’ve died out due to the various diseases we are exposed to daily. Evolution is a constant undergoing process as our surroundings continue to change. We must adapt to these changes in order to successfully survive. I want to

Human evolution: the study of how and why our human ancestors changed over millions of years.

According to Dr. James Krupa of The University of Kentucky “evolution is the foundation upon which all biology rests.” In biology, evolution is the genetic change in characteristics over generations and is dependent on the process of natural selection. ‘The theory of evolution is based on the idea that all species are related and gradually change over time’ (Genome Campus, 2017). Genetic variation is vital to evolution as it affects the physical characteristics or phenotypes of morphology. Natural Selection is affected by environmental factors that act upon a population and result in the mutation of organism through offspring. These mutations enable individuals to adapt to their environments in order to survive, find food, avoid predators and

1. Evolutionary theory describes how populations change over time due to changes in the gene pool. There are several mechanisms that can change a gene pool and allow evolution to occur. Natural selection, mutation, gene flow and genetic drift are some of the driving forces behind evolutionary change. Natural selection and genetic drift are the mechanisms that decrease genetic variation, whereas gene flow and mutation are the driving mechanism to increase genetic variation. Natural selection is basically the understanding that the environment can not support unlimited population growth, and not all organisms are able to reproduce to their full potential due to trait variation. For example, a black fly may

Define evolution? A slow change of something into better form. The word evolution means change, and the process of evolution reflects this definition as it applies to populations of organisms. Biological populations are groups of individuals of the same species that are sub-divided from other populations by geography and are somewhat independent of other groups. Biological evolution, then, is a change in the characteristics of a biological population that occurs over the course of generations. The changes in populations that are considered evolutionary are those that are inherited via genes. Changes that may take place in populations due only to short-term changes in their environment are not

Anthropologists are continuously exploring the far corners of the world in search of answers to how everything came to be and the process by which we as humans appeared on this planet. This is a difficult task and therefore, there are many branches of anthropology which strive to discern the pieces of the puzzle from different perspectives and approaches. Through the implementation of the scientific method, anthropologists have tested numerous hypotheses to create theories like the Theory of Evolution. First documented by Darwin, natural selection, the process by which a more fit individual survives and passes on their adaptive traits, has been discovered to play a crucial role in the evolution of

Human biological diversity encompasses much more than the characteristics seen by the naked eye. Our species walked new and unique paths to arrive at our present existence. Our journey resulted in the achievement of many innovative and unique physiognomies allowing us to survive and reproduce. What characteristics have our species evolved and which most greatly shaped our evolution by conferring additional advantages in survivorship? Although there are many remarkable characteristics that have evolved the most striking

Both evolutionary and functional explanations of physiology and behavior are important in understanding why certain genes evolve across various generations. The evolution of structural characteristics and behaviors explain many of the questions often asked as to why humans, as well as other species, are the way that they are. More specifically, evolutionary psychologists use adaptive theories to comprehend why particular behaviors are promoted across generations or cultures, while others are not. Both structural and behavioral advantages managed to the survival rates in countless populations, at least in ancestral times (Kalat, 2013). However, while current evolutionary trends are no longer focused on just the adaptations relating to survival,

Divergent evolution occurs when two populations of the same species are separated and become genetically different. Two types of divergent evolution are demonstrated in Figure 2. One type is called Allopatric speciation; this occurs when a population or group of organisms belonging to the same species, are separated geographically. Over time, the separated groups develop different traits due to environmental differences. In Figure 2a, the grey fish evolved in a lake the receives salt water runoff, they would need to have evolved traits to survive the increased salinity.

What is convergent evolution and how can convergent evolution in the past affect the description of fossilized species? Convergent evolution is when two branches of evolution converge on the same feature by separate paths. For example, birds and bats share the feature of having wings and being able to fly. But they arrived at that ability through separate paths, not through their common

Understanding human evolutions is important for identifying the stages of humanity and for understanding how our societies have developed. When most of us think about human

Abstract evolution has occurred in humans for millions of years; however, in a modern society many scientists and evolutionists are now debating whether or not it is still occurring, and if it follows the same rules. With all of the new technology humans have created, some experts believe that humans have essentially conquered nature, and no further evolutionary changes will occur. Still, others hold opposing views; some experts believe that evolution is still occurring, but modern societal advancements have changed the rules. These experts say that the changes in evolution are a result of recent medical advancements that allow doctors to perpetuate genes that would not have lasted years ago. Additionally, others maintain that evolution is

Convergent Evolution is the process where an unrelated or distantly related organism develops similar characteristics in order to adapt to the same environment. When the time passes this adaptations made by the organism makes the species to add up similar favorable traits in very different species.
