Taxonomy PRE-LAB QUESTIONS 1. Use the following classifications to determine which organism is least related out of the three. Explain your rationale Table 2: Classifications European Fire- American Green Tree Frog Eukarya Animalia Chordata Amphibia Anura Hylidae Tursipops Cinera Classification Level Domain Bellied Toad Eukarya Animalia Chordata Eastern Newt Eukarya Animalia Chordata Kingdom Phylum Class Order Family Genus Amphibia Amphibia Anura Bombinatoridae Bombina bombina Caudata Salamandridae Notophthalamus viridescens Species

Explanation / Answer

To determine the level of relatedness, it is essential to see how many classification steps are common for each of the above organism. In the above classification, there are 8 steps of classification. From step 1 to 4 (i.e., from Domain to Class), all the 3 organisms share the same characteristics. However, the difference lies in step no.5 (Order).

Here, both the american green tree frog, and european fire-bellied toad belong to the order Anura, whereas, the eastern newt belongs to the order Caudata.

This means that american green tree frog, and european fire-bellied toad are related more closely to each other.

The least related specis is eastern newt.
