Question

Quizplus · Accepted Answer

Prokaryote phylogenies are different from mammal phylogenies because there is a high degree of lateral gene transfer in prokaryotes, whereas mammals generally have a vertical transmission of genes from parent to offspring. This makes it more difficult to construct prokaryotic phylogenies based on a common ancestor. Mammal phylogenies are typically based on evidence from DNA, whereas prokaryotic phylogenies can also incorporate RNA evidence.
