**What This Document Is**
This is a student worksheet designed to accompany the HHMI “Great Transitions Interactive” module for Biology I/Lab (BIOL 1500) at Nova Southeastern University. It focuses on the evolutionary journey of tetrapods – four-limbed animals – from their fish ancestors. The worksheet guides students through an exploration of transitional fossils and the anatomical changes that occurred during this significant evolutionary shift.
**Why This Document Matters**
This assignment is for students enrolled in BIOL 1500. It’s used to reinforce learning from the interactive module and assess understanding of key concepts related to vertebrate evolution. Completion of this worksheet demonstrates comprehension of the anatomical evidence supporting the fish-to-tetrapod transition. It is likely part of a graded assessment for the course.
**Common Limitations or Challenges**
This worksheet *requires* access to the HHMI “Great Transitions Interactive” module to be completed. It does not provide the foundational information about evolution or anatomy; it expects students to actively engage with the interactive resource and then record their observations and answers. It is a tool for *applying* knowledge, not acquiring it.
**What This Document Provides**
The full worksheet includes a series of questions and prompts organized around key anatomical features – gills/lungs, ribcage, limbs, and head/neck. It asks students to analyze specific fossil forms like *Tiktaalik* and *Acanthostega*, comparing their characteristics and inferring their lifestyles. This preview only shows a selection of the questions; the complete document contains all questions from the interactive module, covering the introduction, anatomical features, and fossil comparisons.
