De Leon Grade and Section: 12- St. Kateri Tekakwitha (12 STEM) G12: Evidences of Evolution Activity I. Research on the different pieces of evidence of evolution then complete the table. Evidence Picture Description and Explanation 1. Biogeography Biogeography delves into the intricate patterns of species and ecosystem distribution across both geographical expanses and geological eras. Predictable variations in organisms and biological communities emerge along gradients such as latitude, elevation, isolation, and habitat area, offering a nuanced understanding of their spatial and temporal dynamics. 2. Fossil Record The fossil record comprises discovered fossils and their corresponding relative ages. Examining patterns within the fossil record allows scientists to unravel the intricate history of life on Earth. One notable insight gleaned from the fossil record is the overarching trend of increasing organism complexity throughout the passage of time. 3. Homology Homology denotes the resemblance in traits or features among diverse species or organisms, stemming from a shared ancestry. These characteristics are frequently inherited from a mutual evolutionary forebear. Although homologous structures or traits may fulfill varied functions in the organisms they belong to, their structural likeness signifies a unified ancestral source. 4. Embryology Embryology, a specialized field within biology, investigates the growth and formation of embryos, the initial phases of an organism's life cycle. This area of study delves into the intricate processes and stages involved, starting from the fusion of egg and sperm to the emergence of a fully developed organism. It encompasses the examination of cellular division, specialization, and the shaping of tissues and organs through morphogenesis. II. For each animal, indicate what type of movement each limb is responsible for. Animal Primary Function Human Using tools, picking up and holding objects Whale The flippers of a whale are adaptations of its limbs, serving to aid in swimming, rotation, and propulsion. Cat The forelimbs and hindlimbs of a cat play essential roles in its ability to walk, run, jump, and climb. Additionally, the forelimbs are instrumental in enabling the cat to pounce and capture its prey. Bat The bat utilizes its forelimbs for flying and gliding, while its hind limbs assist in gripping onto trees in an inverted position. Bird A bird's forelimbs play a role in flying and gliding, whereas its hind limbs are utilized for walking, perching, and swimming. Crocodile The limbs of a crocodile contribute to its ability to crawl, walk, and swim, preventing the reptile from drowning. III. Direction: Compare the anatomy of the butterfly and bird wing below.
