In this activity, you will be creating a concept table of the theories of evolution. You will be given the names of nine scientists that have had an Impact on what we currently believe about evolution and you will explore their ideas and theories. You will complete a table that follows the theories of evolution through time. Your table will include the following scientists: • Linnaeus • Hutton • Lamarck • Malthus • Cuvier • Lyell • Darwin • Mendel • Wallace The table will include the name of the scientist, approximate dates, explanations of the concepts they explored, and the general theory or topic they are credited with. Below is the table you will fill in, with an example of what one part of the table might look like. Use the example to guide you with how much deta is required and how in-depth your responses must be. Be sure to include the following key terms somewhere in your table. Key Terms: gradualism, catastrophism, taxonomy, use & disuse theory, paleontology, binomial nomenclature, evolution, natural selection uniformitarianism, inheritance BIVXx X, -E E D EI3 Font Sizes
Evolutionary Genetics
Evolution is known as continuous changes that occur to adjust organisms in their changing environment over many generations. Various theories have been proposed to illustrate the origin of life and organic evolution. The most accepted one is the theory of natural selection by Charles Darwin. According to his postulate, organisms undergo a struggle for existence due to overproduction. To survive in nature, they acquire variations. The inheritable variations are selected by nature, and it leads to the survival of the fittest.
Phenotype Frequency
The majority of populations have a certain degree of variation in their genetic pools. Scientists can predict the genetic variation happening over time by measuring the amount of genetic variation in a population and these predictions assist them in gaining important insights into the processes that allow organisms to adapt to the environment or to develop into new species over generations. This process is referred to as the process of evolution.
Hardy Weinberg Equilibrium
The frequencies of allele and genotype were maintained constant from one generation to another due to the absence of other evolutionary forces. It is otherwise called the Hardy Weinberg principle the field of population genetics.
Evolution in biology can be mostly simply described as descent with modifications, which comprises of evolutionary changes at genetic, organismal or population level. Evolution helps us to understand the history of life since the first advent of life on earth (almost 3.7 billion years ago) till present. Living organisms have evolved since billions of years and present day species have all evolved from a common ancestor and then have diverged at different points of time during the evolution of life. Many scientists gave different hypothesis about the theory of evolution since the beginning of 18th century. Today, Darwin's theory of evolution by natural selection is the most convinced idea of all.
