Answer:

Yes, there are living organisms today that appear to have not evolved much. These organisms are often referred to as "living fossils" because they have retained many characteristics that are similar to their ancient ancestors, despite millions of years of evolutionary change.

One example of a living fossil is the coelacanth, a type of fish that was thought to have gone extinct around 65 million years ago. However, in 1938, a living coelacanth was discovered off the coast of South Africa. The coelacanth has many primitive characteristics, such as lobed fins and a primitive lung-like swim bladder, which are similar to fish that lived hundreds of millions of years ago.

Another example is the horseshoe crab, which has remained relatively unchanged for over 450 million years. Horseshoe crabs have a hard exoskeleton, compound eyes, and a unique blood clotting system that has remained virtually unchanged throughout their long evolutionary history.

These living fossils provide valuable insights into the past and help scientists understand the evolutionary processes that have shaped life on Earth.
