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?

A. Linneaus's system of classification
B. phylogentic system of classification
C. Whittaker's system of classification

Answer 1

Correct answer: B). Phylogentic system of classification

The scientist will use the phylogenetic system of classification. As is uses evolutionary relationship for classifying an organism. The phylogentic relationship between the organism is given by the degree of evolutionary distance. This system names only clades which are a group of organism that is descended from the common ancestor.

Hence, the correct answer would be option B

Answer 2

A scientist will use the phylogenetic system of classification to determine if the two reptile like organisms belong together in the same clade. This system is based on evolutionary ancestry. The correct answer is B.
