Please help with the following prompt using as much details as possible. "One argument that is often made to invalidate evolution by natural selection is that some features of an organism are so complicated and need to work together in order to precisely function that it is impossible for such structures to arise from simpler ones by the random processes of mutation and selection: complicated design requires a designer. Using evidence from real organisms, explain how a complicated structure can arise from a simpler ancestral feature. You can use either an anatomical feature or molecular one."

Natural selection acts upon ____________________________, evolution upon _______________________________. What is the gene pool and how does natural selection act upon it? If a version of a gene confers an advantage to survival and reproduction, that version of the gene will be favored by natural selection and we can expect the frequency of that gene to ______________________ within the population over time. Versions of the gene that do not confer an advantage (or confer a disadvantage) should become _______________ prevalent . This generation to generation change in the gene pool is called ________________________. Changes to the genetic makeup of a population and the individuals within it can arise via two mechanisms. List and describe both. Both of these processes are ________________________________. Once created, new combinations of genes will be acted upon by _________new alleles_______________________. How is Darwinian “fitness” different than the typical definition used in…
