Many bacteria and protists reproduce asexually (binary fission). How does this challenge the Biological Species Concept? How do taxonomists classify these organisms?
This is a higher-level critical thinking question. It forces you to move from memorizing "Reptilia = cold-blooded, scaly" to understanding that classification should reflect ancestry, not convenience.
These questions often introduce Cladistics . Instead of just grouping things by "how they look," students must group them by "who they are related to." This shifts the focus from static categories to dynamic phylogenetic trees , which show how life has branched out over millions of years. Common Themes in Extension Answers
