Matt Munson is a member of Beasley Allen’s Mass Torts Section, handling defective medical device litigation. He is lead attorney on cases involving Zimmer Biomet’s Comprehensive Reverse Shoulder System and has been with us since 2006. Matt decided to pursue law after finding irregularities in a non-fiction novel while writing a literature paper at Auburn University Montgomery. By making a long-shot phone call to the author, Matt questioned him until he admitted it was not an entirely first-person account, as he had led everyone to believe. The author told Matt he should think about becoming a lawyer, and after taking a few pre-law classes, Matt changed his major and then attended Western Michigan University’s Thomas M. Cooley Law School.

For Natural Selection to occur there must be some level of variation among the population that is heritable.

This is wrong because an organism doesn’t have to have the best fitness or survive the longest to pass on a gene successfully to the offspring. Usually nature chooses the traits to pass on to offspring, it passes traits that will be beneficial to the organism for survival. A true statement would be; natural selection can fully be explained by how successful the genes are passed to the offspring. b) This statement is true. Variation is necessary for natural selection to occur because natural selection has to do with the difference in traits.

I think that the video, “How Evolution Works, Part 2” presented the case it was trying to make the best. I think that people cannot accept the theory of evolution if they only understand the contents of the Bible in a literal sense. I cannot accept much of the scientific knowledge currently in common use, not just evolution, but also when the earth was created. I think we can make a judgment that evolution and creationism are compatible by recognizing scientific facts and by how flexible the Bible is. Someone can ask if dinosaurs should come to the Bible if God made them.

BSC 1020 – Reflection Paper Unit G Evolution and its Processes This unit covers the theory of evolution, its mechanisms, the modern synthesis of genetics and evolution, and classification of species. The first chapter describes the history involved in Darwin’s theory of evolution. It talks about the evidence that supports evolution like the fossil record, biogeography (geographical distribution of species), comparative anatomy, comparative embryology and molecular biology. These collections of evidence help explain how species evolve from a common ancestor with gradual changes over time due to natural selection. Natural selection states that certain traits of an organism inside a population are better for adapting to the environment.

The main aspects of Darwin’s Natural selection is about living organisms with suitable and inheritable traits for the survival and reproduction of new species. Offsprings that inherit better traits have an improve the population. For example; a giraffe will a long neck because it eats from tall trees. It is because of the tall trees( environment) that the Giraffe eventually evolves long neck as a mechanism for survival. By leaving an impact on their physical and social environment, organisms may affect the evolution of their own descendants, quite apart from changing the conditions for themselves.

Evolution is the process by which an organism develops different traits in order to survive in its on environment. Through a study of genetics one can find that organisms do, in fact, develop new traits in order to evolve to their

Evolution is the process of genetic change in a population over generations. Natural selection, an agent of evolutionary change, is differential reproduction based on genetic constitution. Natural selection results in adaptation and acts on phenotype, which is the expression of genotype due to environmental effects. An adapted individual is one that is well adjusted to succeed in its environment.

As a biology student, evolution was one of the first topics covered in my introductory biology classes at ASU. When I have been taught evolution it almost always begins with a tale about Darwin, the Galapagos Islands, and those magical finches. Using Darwin’s discovery, terms such as mutation, genetic drift, and adaptation were introduced to me. The basic consensus of evolution that I have gained from these biology courses is that species adapt to their environment in ways that allows them to survive more successfully. This ability to survive more effectively, allows these species to procreate more.

This process is known as natural selection, which explains how Charles Darwin’s theory of evolution can occur. 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.

The four main driving forces of evolution are natural selection, mutation, genetic drift and gene flow. The process of natural selection involves organisms possessing certain physical characteristics that can be deemed "advantageous" to the survival in their environment. This, in effect, allows them to reproduce and pass on those same genes at a higher rate than the same organisms that do not have that same competitive advantage. Mutation is the random of an organism's gene or chromosome that are the result of an addition, removal, or substitution of certain parts of the DNA sequence. Genetic drift is the alteration of allele regularity found in one generation as compared to the next generation.

All creatures on Earth change relentlessly to adapt and survive in a new environment. Human beings are not an exception to this rule. Evolution by Hall and Hallgrimson had stated that Darwin’s theory of evolution is a change in genetic traits of biological population from one generation to another. The dominant, or adaptable genes will replace the recessive genes in the gene segment. The whole process of evolution, however, does not happen rapidly.

Evolution and natural selection are very closely related. They both are also very important in understanding the human body. Evolution is the changes in the genetic makeup of a population over generations (73). Understanding evolution helps us solve biological problems that impact our lives and those around us. The theory of evolution states that all the lifeforms on earth share a common ancestor as a result of variation and selection over a very long time.

Evolution by natural selection is one of the best sustained theory's in the history of science, supported by evidence from a wide variety of scientific disciplines, including palaeontology, geology, genities and developmental biology Origin of whales: In the first edition of the origin species In 1859, Charles Darwin speculated about how natural selection could cause a land mammal to turn into a whale, as a hypothetical examples, Darwin used North American black bears which where known to catch insects by swimming in the water with there mouths open. The idea didn’t go very well with the public. Darwin was so embarrassed by the ridicule he received that the swimming bear passage was removed from later editions of the book.
