Question

A wildlife scientist finds two reptile-like organisms. Both have a post-anal tail, claws, and some common characters of reptiles, but they differ in size, color, pattern, and design. To find out whether they belong to the same clade, which classification system should the scientist look to?

Answer 1

I would say they need to look to Linneaus System of Classification, because he devised the taxonomical system of class, order, phylum, species variety, etc.
