Which of the following about the peopling of the Americas is FALSE?
A. Analysis of DNA suggests the Americas were settled by more than one haplogroup-a lineage marked by one or more specific genetic mutations.
B. The first migration(s) of people into the Americas may date back 18,000 years.
C. Researchers calculate that it would have taken from 600 to 1,000 years for the first Americans and their descendants to travel by land from the southern part of the Canadian ice-free corridor to Tierra del Fuego at the southern tip of South America-a distance of more than 8,680 miles.
D. The first migration of people into the Americas reached the continent's southwestern coasts from the Pacific islands.
E. The Clovis people were not the first settlers of the Americas.

In 1997, ancient DNA was extracted from one of the Neandertal bones originally found in Germany's Neandertal Valley in 1856. This was the first time the DNA of a premodern human had been recovered. When comparing this DNA with that of modern humans, the researchers found
A. 27 differences between the two, many more than would be expected in closely-related humans, suggesting that their common ancestor probably lived 600,000 years ago. B. only 5 to 8 differences between the two, as is typical of closely-related humans, placing Neandertals within modern humans' direct line of descent. C. many more mutations in the Neandertal DNA, suggesting the species had been around 100,000 years longer than previously estimated. D. no differences, demonstrating that Neandertals and modern humans are the same species. E. that the two samples were not comparable, since the Neandertal DNA was molecularly different from the DNA of the reference sample.
