Why was the scallop among the snails? What additional tests could be used to examine evolutionary relationships among molluscs ? How was the name of different cone snail species decided? Where are cone snails found and what are their feeding habits?

BIO 101 Hands-on Activity – Taxonomy Activity

Directions

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.
take notes, describing each step of identifying and selecting snails as you work through the activity.  take a screen shot of the final drawing showing the evolutionary relationship of all snails listed and answer the following questions:
Why was the scallop among the snails?
What additional tests could be used to examine evolutionary relationships among molluscs ?
How was the name of different cone snail species decided?
Where are cone snails found and what are their feeding habits?
Describe the evolutionary history of snails . In which eon, era and period did the first snails evolve?
