The phylogenetic tree below shows similarities in the amino acid sequences of cytochrome-c of several organisms. which organism is most distantly related to the rhesus monkey? a phylogenetic tree with labels lamprey, frog, chicken, mouse, rhesus monkey, and human a. human b. frog c. chicken d. lamprey

In a phylogenetic tree, the organisms that are closely linked tend to be on branches that are closer and share a common branch. This means that these organisms shared one or many common ancestors.
The organism least related to the rhesus monkey is D. lamprey. This is evident from the tree since these two organisms stopped sharing common ancestors very long ago.
