Why the term living fossil is a misleading way to describe ancient species
In short: Animals like crocodiles and horseshoe crabs are often called living fossils because they appear unchanged for millions of years. This video explains why this label is scientifically inaccurate and how evolution continues to shape even the most ancient-looking organisms.
The concept of a living fossil suggests that certain creatures have stopped evolving since the age of the dinosaurs. However, organisms such as crocodiles, horseshoe crabs, and the tuatara are not frozen in time. Despite their prehistoric appearance, these species remain subject to the ongoing processes of evolution.
By examining these animals, we can see that evolution is a constant force rather than a process that halts for specific lineages. The label itself obscures the reality that these organisms have adapted and changed throughout their long histories.
