Question

A scientist is trying to classify an unknown organism. What would be the BEST characteristics to use?

Color
Color

Bone structure
Bone structure

Age
Age

Number of offspring
Number of offspring

Molecular structure (DNA/RNA sequencing)

this response is not a response but will keep noted there is one other answer that is simular which is "Bone structure"

Physical characteristics such as bone structure, color, age, and number of offspring may not be the most reliable when classifying an unknown organism. The best characteristic to use would be the molecular structure, specifically by analyzing DNA/RNA sequencing. This method provides more accurate and detailed information for classification.
