The evolution of sharks is a fascinating story of adaptation and survival. Sharks have developed a range of unique characteristics, such as their electroreception, lateral line system, and cartilage skeleton, which have helped them to thrive in the oceans for millions of years. Sharks have also played a significant role in human history, with many cultures having myths and legends about these mysterious and powerful creatures. Today, sharks face numerous threats from overfishing, pollution, and habitat destruction, and it is more important than ever to understand and appreciate these vital members of the marine ecosystem.
