LIVING FOSSIL Meaning and
Definition
-
A "living fossil" is a phrase used to describe a species that has retained many of its ancestral characteristics over millions of years, without undergoing significant evolutionary changes. It refers to organisms that have survived for long periods in relatively unchanged forms, often resembling their ancient ancestors in morphology and behavior. The term "living fossil" is not a scientific classification but rather a popular expression used to describe these unique creatures.
Living fossils are typically found in groups of organisms that have long evolutionary histories, such as certain fish, plants, and invertebrates. These species often exhibit primitive features that resemble their ancient relatives, giving valuable insights into the history and evolution of their respective taxa. They are considered evolutionary relics, as they provide a window into the past and offer glimpses of ancient evolutionary processes.
One famous example of a living fossil is the coelacanth, a lobe-finned fish that was thought to have gone extinct approximately 66 million years ago but was discovered alive in the deep ocean in 1938. Other examples include the horseshoe crab, which has existed relatively unchanged for hundreds of millions of years, and the ginkgo tree, which can be traced back to the time of the dinosaurs.
The concept of living fossils highlights the fascinating interplay between continuity and change in the natural world. Despite the substantial transformations that occur during evolution, some species manage to endure through vast stretches of time, embodying the concept of "stasis" in the evolutionary process.

Etymology of LIVING FOSSIL
The term "living fossil" was first introduced by the French paleontologist Louis Agassiz in the mid-19th century. It is a combination of the words "living" and "fossil".
The word "living" derives from the Old English word "lifian", meaning "to be alive". This word itself has Germanic roots and is related to the Old High German word "libēn" and the Old Norse word "lifa".
The word "fossil" has Latin origins, stemming from the Latin word "fossilis", which means "dug up". It evolved from the verb "fodere", which translates to "to dig". In ancient Latin, "fossilis" referred specifically to minerals that were mined or dug out of the earth.
