Allied College Module 4 Morphological Characteristics of the Sea Shells Discussion

Go to the Biodiversity and Evolutionary Trees: An Activity on Biological Classification (Links to an external site.) and work through the activity sorting sea shells based on morphological characteristics to study evolutionary relationships.
Please take notes, describing each step of identifying and selecting snails as you work through the activity. Please take a screen shot of the final drawing showing the evolutionary relationship of all snails listed and answer the following questions:
1. Why was the scallop among the snails? (HINT: Watch “Dr. Olivera discusses major molluscan groups [Duration 04:25] (Links to an external site.)“)
2. What additional tests could be used to examine evolutionary relationships among molluscs (snail species)? (HINT: Watch “Dr. Olivera discusses how to classify shells [Duration 03:26] (Links to an external site.)“)
3. How was the name of different cone snail species decided? (HINT: Watch the video “Dr. Olivera discusses species names [Duration 02:02] (Links to an external site.)“)
4. Where are cone snails found and what are their feeding habits? (HINT: Click on snail images on the final evolutionary tree for more information about species).
5. Describe the evolutionary history of snails (Molluscs). In which eon, era and period did the first snails evolve? (HINT: Textbook, chapter 27.3)
