Question

A recent study compared the Homo sapiens genome with that of Neanderthals. The results of the study indicated that there was a mixing of the two genomes at some period in evolutionary history. Which of the following potential discoveries of additional data might be consistent with this hypothesis?A) some Neanderthal sequences not found in living humans

B) a few modern H. sapiens with some Neanderthal sequences
C) duplications of several Neanderthal genes on a Neanderthal chromosome
D) some Neanderthal chromosomes that are shorter than their counterparts in living humans

Answer 1

A few modern H. sapiens with some Neanderthal sequences.

Step-by-step explanation:

The evolutionary study is important to understand the evolution pattern of the organisms and their common ancestors. The human evolution can be revealed by the molecular and biochemicals evidence.

The DNA and protein sequence similarity are used to construct the phylogeny tree. The BLAST tool is used for the alignment of the sequences. The studies suggested that Homo sapiens genome is mixed with that of Neanderthals. This might be possible that DNA sequences of few modern H. sapiens is similar with the Neanderthal sequences.

Thus, the correct answer is option (B).
