ancient dna

Scientists have discovered ancient dna, some dating back two million years. This DNA, found in Siberian permafrost and Greenland ice, offers a glimpse into Earth's past. Researchers are reconstructing ancient ecosystems and understanding how creatures like mammoths evolved. These frozen archives are revealing history's secrets, showing that the planet remembers.

In 1996, two students discovered an ancient skeleton, dubbed "The Ancient One," near the Columbia River. DNA analysis revealed the 9,000-year-old remains are genetically linked to Native Americans, resolving a long-standing debate. This discovery revolutionized archaeology, emphasizing respect for indigenous sovereignty and memory, culminating in the skeleton's return to tribal descendants for a traditional burial.

A car park in Leicester unexpectedly yielded the remains of King Richard III, the last English king to die in battle. Scientific analysis, including osteological evidence, DNA comparison with descendants, and examination of battle injuries, confirmed the skeleton's identity. This discovery bridges the medieval and contemporary worlds, highlighting the rich history beneath urban landscapes.

Scientists discovered the devil worm, Halicephalobus mephisto, living 1.3 kilometers underground in a South African gold mine. This nematode, adapted to extreme heat, pressure, and low oxygen, challenges previous understandings of where complex life can exist. Its genome reveals evolved heat stress responses, suggesting it's a deep-Earth native, not just a survivor.

Ancient Bristlecone Pines in the Great Basin mountains exhibit remarkable longevity, surviving millennia in harsh conditions. These trees, immune to cellular ageing, possess dense, resinous wood and conserve energy through a unique strip-bark design and long-lasting needles. Their rings offer invaluable insights into Earth's climate history, teaching a profound lesson in the power of patience over speed.
