Describe the evolutionary change leading to antibiotic resistance using the theory of descent by modification with natural selection.

Antibiotic resistant bacteria are a significant health issue worldwide. Penicillin initially was ext Show more Antibiotic resistant bacteria are a significant health issue worldwide. Penicillin initially was extremely effective in treating bacterial infections by killing pathogenic bacteria. Today many bacterial pathogens are resistant and penicillin does not cause significant bacterial cell death. An explanation of evolutionary change by the theory of inheritance of acquired characteristics (IAA) was proposed by Jean-Baptiste Lemarck. Athough the explanation was rejected soon after it was proposed it remains as an extremely prevalent misconception of evolution. For illustrative purposes describe the evolutionary change leading to antibiotic resistance using the theory of inheritance of acquired characteristics. Charles Darwin described evolutionary change as descent by modification with natural selection. Describe the evolutionary change leading to antibiotic resistance using the theory of descent by modification with natural selection. Be sure that your explanations are different and illustrate the principles of each theory. Show less
