Color code each of the bones according to this key: For each animal, indicate what type of movement each limb is responsible for. Compare the skeletal structure of each limb to the human arm. Relate the differences you see in form to the differences in function.
OBJECTIVE: In this lab activity you will learn about homologous, analogous, vestigial structures; fossils, embryology and biochemistry and their significance in evolution theory. OBSERVATIONS: 1. COLOR CODE the bones according to instructions. 2. Describe the function of each set of bones below: ANIMAL FUNCTION Human Whale Cat Bat Bird
Color code each of the bones according to this key: For each animal, indicate what type of movement each limb is responsible for. Compare the skeletal structure of each limb to the human arm. Relate the differences you see in form to the differences in function.
Many organisms possess vestigial structures that have no apparent function, but that resemble structures their presumed ancestors had. Natural selection explains why some animals have leftover body structures that aren't still needed.
OBJECTIVES: In this lab you will learn about homologous, analogous, and vestigial structures and their significance in evolution theory. MATERIALS: Colored pencils and worksheet. PROCEDURES AND OBSERVATIONS: PART I. HOMOLOGOUS STRUCTURES (definition): ________________________________.
Study with Quizlet and memorize flashcards containing terms like why do homologus structures of the bones are evidence of evolutionary relationships, wisdom teeth (probable function; why vestigial), little toe (probable function; why vestigial) and more.
31 Οκτ 2023 · Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures. Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds.
