Question: Ötzi’s gut bacteria showed ________.

Option 1: 'Genes and proteins are not the same thing' — This statement concerns a basic biology concept about the relationship between genotype and phenotype, but it does not address what Ötzi’s gut bacteria reveal about historical microbial distribution or migration. It’s a general fact and not a finding specific to Ötzi’s microbiome.

Option 2: 'The paleo diet can get you murdered' — This option is a sensational, non-scientific claim that conflates dieting trends with criminal outcomes. It has no bearing on microbiology or Ötzi’s gut bacteria and should be dismissed as irrelevant and inaccurate in this context.

Option 3: 'Helicobacter pylori causes ulcers' — While H. pylori is known to be associated with ulcers in modern humans, this statement is a factual microbiology claim rather than a specific observation about Ötzi’s gut microbiome. Even if H. pylori can be found in ancient remains, the option doesn’t directly reflect Ötzi’s gut bacterial pattern or migration history.

Option 4: 'Microbes move to new regions along with people' — This reflects a well-supported concept in ancient microbiome studies: human migration and contact can carry associated microbes to new geographic regions. Ötzi, a mummy from the Copper Age, provides evidence that gut bacteria could accompany humans as populations moved, leading to microbial exchanges and regional microbiome patterns observed in ancient remains.

In summary, option 4 correctly ties Ötzi’s gut bacteria to the broader idea that microbes travel with humans during migrations, whereas the other options either discuss general biology not specific to the evidence from Ötzi, present sensational or unrelated claims, or describe a separate factual idea not directly tied to Ötzi’s microbiome findings.
