Evidence Supporting Evolution SHS Biology: Mr. Smit Homologies / Homologus Structures Homologus arrangements of bones and other anatomical structures across various species. Vestigial organs or structures Anatomical structures reduced in size and function that serve little or no purpose in the present day organism Modern day examples of natural and artificial selection All domesticated animals have been artificially selected to have traits beneficial to raising in captivity. If the process can happen artificially – why not in nature? http://www.gly.uga.edu Bacterial resistance may be the most pressing danger in health care. Staphylococcus aureus is continually evolving resistance to antiseptic methods and antibiotics. In addition, Flu Vaccines need to be produced annually to adapt to the newly evolved form. Institut Pasteur Caption: a cluster of S. aureus bacteria observed using electron microscopy Biochemical Evidence: Common ancestry can be traced and determined by analysis of DNA similarity comparisons. Comparisons exist in base pair sequences, amino acid sequences, and tertiary protein structure (ex – myoglobin human to chimp). Transitional Species Tiktaalik, water to land Archaeoptyryx, Reptile to bird
