How are prokaryote phylogenies different from mammal phylogenies?
A) There is a high degree of lateral gene transfer in mammals.
B) Mammal phylogenies are constructed from evidence based in DNA, whereas prokaryote phylogenies are based in RNA.
C) There is a high degree of lateral gene transfer in prokaryotes.
D) The phylogenetic reconstruction process is much simpler for prokaryotes because they are much smaller.
E) Mammal phylogenies are constructed from evidence based in RNA, whereas prokaryote phylogenies are based in DNA.

Question

Quizplus · Accepted Answer

Prokaryotes are known for their high degree of lateral gene transfer, which can make phylogenetic reconstruction more difficult. Mammal phylogenies are typically constructed using DNA evidence, but this is not a major difference between prokaryote and mammal phylogenies. The size of the organism does not necessarily make the phylogenetic reconstruction process simpler, so D is also not a correct choice. E is also incorrect as mammal phylogenies are constructed using DNA evidence, not RNA.
