Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.
Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related

Thank you for posting your question here at brainly. Below are the choices. The answer is 4.
1)Cell signaling is observed in single-celled organisms that reproduce asexually through binary fission.
<span>2)The mechanisms of cell signaling are similar in organisms whose last common ancestor lived a billion years ago. </span>
<span>3)The pathways in primitive organisms, such as bacteria, are shorter than in those in advanced organisms, such as humans. </span>
<span>4)Simple forms of life that have not evolved much since the origin of life, such as prokaryotes, use cell signaling.</span>
