Which of the following would be the best approach to constructing a phylogenetic tree that spans two very distantly related organisms (e.g., bacteria and humans) and the major branches of organisms in between?
a. Analyze the size of the genomes as size increases; the more related an organism is to humans.
b. Analyze mitochondrial DNA as this makes lineage tracing easier.
c. Analyze sequences in a region of DNA with a very fast molecular clock so that all possible differences can be captured.
d. Analyze sequences in a gene with an incredibly slow molecular clock.
e. Analyze the position of genes on the chromosomes.
