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. What data were discovered that suggested this conclusion?

Answer 1

A recent study comparing the Homo sapiens genome with that of Neanderthals found evidence of mixing between the two genomes. DNA analysis revealed similarities between Neanderthal DNA and modern European-derived populations, while modern European and Middle Eastern populations have been found to have Neanderthal DNA.

Step-by-step explanation:

A recent study comparing the Homo sapiens genome with that of Neanderthals found evidence that suggests mixing of the two genomes at some point in evolutionary history. DNA analysis revealed similarities between Neanderthal DNA and the DNA of modern European-derived peoples. In addition, modern European and Middle Eastern populations have been found to have between 1 and 4 percent Neanderthal DNA. These findings indicate that mating between Homo sapiens and Neanderthals was relatively common.

Answer 2

The genome sequencing showed a similar sequence.

Step-by-step explanation:

The Neanderthals lived with modern humans until they got killed or disappeared by modern humans as a result of the competition around 10,000-12,000 years ago.

The studies on the sexual life of these two groups show that they used to exchanges their genetic material through sexual reproduction and the gene flow occurred between these two species.

Recent studies have provided the evidence that the 99.7 per cent DNA of the Neanderthal is similar to the modern Human beings and they also showed some homology in the DNA sequences like the language Gene is found on the same chromosome in both the species.

Thus, the genome sequencing showed a similar sequence is a correct answer.
