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?

(1 point)
Responses

Humans have the closest evolutionary relationship to Species 1.
Humans have the closest evolutionary relationship to Species 1.
Humans do not have any common ancestors with Species 2 or 3.
Humans do not have any common ancestors with Species 2 or 3.
Humans have the most distant evolutionary relationship to Species 4.
Humans have the most distant evolutionary relationship to Species 4.
Humans have the fewest common ancestors with Species 1 and 4.

Answer 1

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

Humans have the closest evolutionary relationship to Species 1.

This conclusion is based on the highest percentage of amino acid sequence similarity (85%) between humans and Species 1 compared to the other species, indicating a closer evolutionary relationship.
