Evolution

  • blind cave fish
  • Bird in flight.  Flight is a mode of locomotion that has co-evolved in several lineages in the animal kingdom.  Here, we see a roseate spoonbill (Platalea ajaja) in flight over Everglades National Park in Florida.  Photo credit: Brian K. Mealey.

    It's a bird! It's a plane! It's biomechanics!

    Learning Objectives
    Students will be able to:
    • identify and define forces that act on an object in flight.
    • understand the definition of Newton’s third law of motion, which states that with every action there is an equal and opposite reaction, and apply this principle to explain pressure differences and lift generation.
    • generate hypotheses about animal flight efficiency based on examining morphology (anatomy).
    • generate hypotheses correlating wing size and performance during flight.
    • apply their understanding of wing designs and wing relationships to total mass.
    • compare flight principles among animals to understand the co-evolution in several animal groups.
  • “Quantifying variation in biodiversity” Groundhogs (Marmota monax) with conspicuous variation awaiting measurements.

    Teaching Biodiversity with Museum Specimens in an Inquiry-Based Lab

    Learning Objectives
    Students completing this lab module will:
    • Learn how to appropriately handle and measure museum specimens.
    • Develop the necessary statistical skills to analyze museum specimen data.
    • Become familiar with how to search an online museum database and integrate supplemental data with their own dataset.
    • Strengthen scientific communication skills by presenting research to their peers.
    • Demonstrate ability to investigate scientific questions and address obstacles that occur during data collection and integration.
    • Increase proficiency in managing and using large datasets for scientific research.
    • Make connections between natural history knowledge and morphology of organisms in developing and testing hypotheses.
