1) Which of the following statements is false? There are few undescribed species of prokaryotes. Analysis of DNA sequences is a useful tool for studying prokaryotic diversity. Many prokaryotes have been difficult or impossible to grow in the lab. Horizontal gene transfer may make it difficult to infer prokaryote phylogenies. 2) One of the ways in which horizontal gene transfer can occur between species is if a virus carries DNA from one host cell to another. Which of the following...

The following statements apply to concepts and material discussed in Chapter 15; identify which statement is TRUE. Answers: A common ancestor of two species on evolutionary trees can be found at the point where the two branches meet. Humans evolved from Neanderthals about 50,000 years ago. Mitochondrial DNA is not particularly useful when trying to determine the movement pattern of humans historically across the globe. Scientists can estimate when species diverged from a common ancestor by comparing their Karyotypes. We...
