Living links to the past

 

Yes, species that are considered to be "living links to the past" are those that have remained relatively unchanged over long periods of time, offering a glimpse into what the world was like millions of years ago. These species are often referred to as "living fossils" because they have persisted through the ages, despite significant changes in their environments and the evolution of other species around them.

Some examples of living links to the past include:

Coelacanth: This fish, which was once believed to be extinct for 70 million years, was rediscovered in 1938 off the coast of South Africa. It is considered a living fossil because it has remained largely unchanged since the time of the dinosaurs.

Horseshoe crabs: These ancient arthropods have remained relatively unchanged for over 400 million years, making them one of the oldest living species on the planet.

Tuatara: This reptile, which is native to New Zealand, is the only remaining species of a group that was once widespread around the world. It is considered a living fossil because it has changed little since the time of the dinosaurs.

Living links to the past provide valuable insights into the evolution of life on Earth and the processes that have shaped our planet over millions of years. By studying these species, scientists can better understand how species have adapted and changed over time, and how they have managed to survive in the face of significant environmental challenges.
