Has Evolution Really Been'seen In The Lab?

1. Define evolution. There are many parameters and conditions that need to be in place in order for evolution to occur. One such parameter is that the population trait in question must be variable. i.e., there will be variations of a trait found in the population. What are some additional parameters and conditions necessary for evolution to take place?

Lastly is artificial selection, which was one of the main pieces of evidence that Darwin used to identify his theory on evolution. Darwin studied and showed how the selective breeding of crops and animals led to highly specialized varieties with unique traits. By studying this he was able to see first hand how evolution can occur by artificial selection. An example would be the Great Dane. Thousands of years ago, the Great Dane was a medium sized breed, but due to artificial selection, humans were able to create a large breed of Great Dane.

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

Evolution theory is not true because it gives a vague explanation of how the world developed to be what it is today and it also fails to explain why it is no longer going on today. As absurd as it is there are people in the world today who believe it majority of them being atheist.

Evolution is the key thread running throughout this text, signifying its importance to the author and readers. It is emphasized greatly because that is how we understand ourselves, our past, present and even the future. Through evolution we have discovered when the first organisms came around and how modifications led to the first fish to migrate to land about 375 million years

Every since the publication of the Origins of Species in 1859, the theory of evolution has been generally accepted by scientists around the world, that is, until 1996 when Michael Behe published his book Darwin's Black Box, calling the theory of evolution into question. The theory of evolution states that individual single point mutations in DNA give rise to the development of new characteristics in species. If these new characteristics are advantageous for survival, then the genes are passed down to new generations. As these characteristics are accumulated, new species develop. However, while most scientists have accepted evolution as a scientific fact, they have yet to answer some basic fundamental questions about the process itself. Michael Behe points to this and proposes that the reason scientists do not yet have all the answers regarding the processes behind evolution is because they have failed to see the intelligent design that lies within it. The author asserts that the "data of biochemistry argues strongly that many molecular machines in the cell could not have arisen through a step-by-step process of natural selection"¦much of the molecular machinery in the cell is irreducibly complex." (Bohlin, 2000, p. 103)

We find that Anaximander of Miletus (611 B.C.-546 B.C.) advanced the traditional evolutionary idea, already quite common in his day, that life first evolved from a type of pre-biotic soup, helped along a bit by the rays of the sun. He believed that the first animals developed from sea slime which had been evaporated by the suns rays. He also

The definition of evolution is that species over time will change. They will start to adapt over time and become a new species. You see this happening throughout the world and over the course of our planets history. In this lab we will be testing different hypothesis and observing them to make conclusions if they can be justified or not. There are three different parts first is the Artificial and Natural selection, the second is the fossil record, third is comparative anatomy, biochemistry, embryology and the last is Biogeography.

For example, the evolution of an eye went through a large number of intermediate steps all of which had some incremental changes when compared to the previous ones. The idea that all evolution was gradual is contested by some authors claiming that some evolutionary changes of profound type happened in only one or two generations when organisms containing some profound genetic mutations found them very useful and established a whole new species (Theißen 2009). Theißen (2009), for instance, claims that the emergence of some features of some organisms cannot be explained any other way than postulating these sudden profound changes. However, gradualism should not be excluded and it can be regarded as a normal mode of evolutionary progress, while these sudden “saltations” provided an alternative mode.

Upon his return to London Darwin concluded thorough research of his notes and specimens many ideas. Out of this study grew several related theories: one, evolution did occur, two, evolutionary change was gradual, requiring thousands to millions of years, three, the primary mechanism for evolution was a process called natural selection, and four, the millions of species alive today arose from a single original life form through a branching process called "specialization."

Evolution is a change over time in species to adapt to new environments. Evolution has been a known fact now, but not all people believe in it. Some believe that evolution is a myth, or a lie. There is evidence that evolution is real.

The theory of evolution postulates that all life evolved from other preexisting life and the differences are attributable to changes from generation to generation (Ayala, 2005). Evidence supporting this theory comes from all branches of biology. Below is a list of five types of evidence supporting this theory.

When Charles Darwin came up with his theory of evolution. The only way he could measure evolution was to compare physical attributes. For example, Darwin picked up on the physical variation of finches when they're located in different parts of the world. Today, we have technological advancements that make it easier to analyze and "measure" evolution. The discovery of DNA and Dominant/ Recessive genes surged forward the study of evolution. It provided an explanation of which/ why certain genes were inherited and others were not. This also backs up natural selection. The best organisms survived and their traits were then genetically passed down to their offsprings. In "Evolution caught in the act: Scientists measure how quickly genomes change"

Though the Theory of Natural Selection holds that organisms evolve over time, gradually becoming more complex and better adapted to their environments, it does not specifically address the mechanisms by which evolution happens. The question of how evolution happens begins with Gregor Mendel, who was a monk living in what is today the Czech Republic. Mendel conducted experiments with Pea plants, establishing that there seemed to be some sort of mechanism which was controlling the physical characteristics which offspring of the pea’s displayed. Mendel came to this conclusion by noting that when he crossed peas which displayed specific characteristics, such as flower color, with plants which exhibited the same characteristic that the offspring

The question 5 for evolutionists might not be clearly stated nowadays. Nonetheless, almost everybody believes that biological pathways might have originated from old forms of life. Some opinions are that organisms might have not being as simple as we might have expected. This idea explains the possible for an ancestral organism to have possessed at least a remotely similar mechanism that could have made modern biological pathways possible. Other ideas revolve around the fact that natural selection (a mechanism that advocates for survival and successful reproduction) was the responsible for it, allowing mutations to modify already existing structures into more complex patterns. Nevertheless, there is no way to check all of the existing reasoning since it is not possible to go back in time. But, although the questions seem hard to assess- given the amount of blind spots that we have to come up with to completely understand evolution- new discoveries happen every day. It might be a matter of time before these answers can be conveniently addressed with better substantial evidence that might still be missing in the meantime.
