Review table below: It shows the amino acids in a segment of the protein, hemoglobin. This protein is present in many species, and is shown compared to that of five species and to human hemoglobin.

Using the data in the table as an indicator of relatedness between species, indicate which species is LEAST closely related to humans.

a
Chimpanzee
b
Rhesus monkey
c
Horse
d
Gorilla
e
Kangaroo

Based on the data in the table, the species that is least closely related to humans is the kangaroo. This can be determined by comparing the amino acids in the hemoglobin of kangaroo and human, and seeing that there are more differences between their amino acid sequences compared to the other species listed in the table.
