Final answer:
The Iceman shared modern-day ailments with contemporary humans such as arteriosclerosis, Lyme disease, lactase persistence, and a predisposition to coronary heart disease, indicating that some health challenges persist through millennia.
Step-by-step explanation:
The Iceman, also known as ""tz"", shares several modern day ailments with 21st-century humans. Although the Iceman lived over 5,000 years ago, advancements in genomic sequencing have revealed that he suffered from conditions that are still prevalent today. Notably, the Iceman's genome displayed signs of arteriosclerosis (hardening of the arteries), which is linked to cardiovascular disease in modern humans.
Additionally, the presence of Borrelia burgdorferi DNA in his remains indicates that he had Lyme disease, a bacterial illness transmitted by ticks that continues to affect people. The Iceman also showed evidence of lactase persistence, meaning he had the ability to digest lactose into adulthood, a trait shared by many modern Europeans. Finally, studies have suggested that he had genetic markers associated with an increased risk for coronary heart disease, which aligns with current trends in heart health issues.
