A scientist compares the amino acid sequences of four species to a similar protein produced by a human. The table shows the percentage of similarity in the amino acid sequence of each organism compared to the human sequence.

Question

Organism Amino acid sequence similarity to human (%)
Species 1 85
Species 2 48
Species 3 39
Species 4 57
Which claim is supported by the evidence in the table?

Answer 1

The claim that is supported by the evidence in the table is:

Humans have the closest evolutionary relationship to Species 1.

This is because Species 1 has the highest percentage of amino acid sequence similarity (85%) to humans, indicating a closer evolutionary relationship compared to the other species listed.
