Question

Consider these phylogenetic trees. The first tree is based on physical characteristics. The second tree is based on structure, genetics, and evolutionary history. Which can be concluded from a comparison of the two phylogenetic trees?
A. Phylogenetic trees are not subject to change.
B. Classification can change with new discoveries and evidence.
C. Classification does not change with more evidence.
D. Phylogenetic trees are inaccurate.

Answer 1

The classification for Opossum changes between the two trees. So the answer is B. Classification can change with new discoveries and evidence.

Answer 2

Answer:

From a comparison of the two phylogenetic trees, we can conclude that: B) Classification can change with new discoveries and evidence.

Explanation:

We have the information regarding two phylogenetic trees. The first tree is based on physical characteristics. The second tree is based on structure, genetics, and evolutionary history.

In the firs tree Duck, Platypus and Opossum seem to be different living organisms and groups. In the second tree Platypus and Opossum share their origins, it means they could be considered similar organisms and groups.

This situation is a consequence of science, They are in constant change. Every day they are new knowledge added, or changed in all sciences because we have more information, more scientific tools more scientists. Due to it, constantly laws, definitions, functions and also Phylogenetic trees can change with time and discoveries.

Finally, From a comparison of the two phylogenetic trees, we can conclude that: B) Classification can change with discoveries and evidence.
