A recent study compared the Homo sapiens genome with that of Neanderthals. The results indicated that the two genomes mixed at some period in evolutionary history. Which of the following data would provide additional support for this hypothesis?
A) finding that Neanderthals and humans have lived in the same geographical areas
B) DNA from a modern H. sapiens that contains some Neanderthal sequences
C) duplications of several Neanderthal genes on a Neanderthal chromosome
D) determining that some Neanderthal chromosomes are shorter than their counterparts in living humans
