These 9 ‘living fossils’ haven’t changed for millions of years

We see evolution all around us, constantly, in every living thing. Yet, in the depths of the oceans, we find a number of “living fossils” reminiscent of creatures from prehistoric times.

In his 1859 book On the Origin of Species, esteemed naturalist Charles Darwin coined the term “living fossil” to describe living organisms that appeared unchanged from their extinct fossil relatives. The term has since been used to describe enduring lineages, relict populations, groups with low diversity, and groups whose DNA has changed little for millions of years.
