As an expert in the field of natural history and biology, I have a deep appreciation for the vast diversity and longevity that can be found within the natural world. When it comes to the question of the oldest living thing ever, it's important to distinguish between different types of organisms and the ways in which we measure their ages. The concept of "oldest" can be interpreted in various ways, such as the oldest individual organism, the oldest species, or the oldest living colony of organisms. Let's delve into this fascinating topic.
Step 1: English Answer
The oldest living thing ever is a complex question to answer definitively, as it depends on how one defines "oldest." If we are talking about the oldest individual organisms, there are several contenders that stand out. One of the most remarkable is the **Great Basin bristlecone pine (Pinus longaeva)**, which can live for thousands of years. The oldest known individual of this species, known as Methuselah, is approximately 4,850 years old and is located in the White Mountains of California, USA. This tree is often considered one of the oldest living organisms on Earth.
Another contender for the title of the oldest living thing is the ocean quahog (Arctica islandica), a species of marine clam. The specimen named "Ming" was found to have lived for an astonishing 507 years before it was unfortunately killed during a scientific study. This clam's age was determined by counting its growth rings, similar to counting the rings in a tree trunk. The ocean quahog is a slow-growing species that can live in cold, deep waters, which contributes to its longevity.
In addition to these individual organisms, there are also ancient living colonies of organisms that are considered among the oldest on the planet. One such example is Pando, a clonal colony of quaking aspen (Populus tremuloides) trees in the United States. Pando is estimated to be around 80,000 years old, although the individual trees that make up the colony have a much shorter lifespan. Pando's age is determined by the fact that it is a single genetic entity, with all the trees being interconnected through a single root system.
Moving beyond individual organisms and colonies, there are also ancient species that have managed to survive for millions of years. The ginkgo tree (Ginkgo biloba) is a prime example, with fossils dating back 270 million years. Although the species has undergone some changes over this time, it is still considered to be living proof of ancient life on Earth.
Lastly, it's worth mentioning some extremophile organisms, such as certain bacteria and archaea, which can survive in extremely harsh conditions and have been found in ancient ice and permafrost. While their individual ages may not be as long as some of the organisms mentioned above, their ability to survive and potentially revive after long periods of dormancy is a testament to the resilience of life.
In conclusion, the title of the oldest living thing ever is not easily bestowed, as it requires a nuanced understanding of the various ways organisms can persist and thrive over time. The Great Basin bristlecone pine, the ocean quahog "Ming," the Pando aspen colony, and ancient species like the ginkgo tree all offer unique insights into the concept of longevity in the natural world.

One specimen has been estimated to be 1,550 years old. A specimen, "Ming" of the Icelandic cyprine Arctica islandica (also known as an ocean quahog), a mollusk, was found to have lived 507 years. Another specimen had a recorded lifespan of 374 years.
