Sharks have been around for over 400 million years, making them older than trees, which first appeared around 350 million years ago. Sharks are among the oldest surviving species on Earth, having existed long before the first dinosaurs roamed the planet. Over time, sharks have adapted to various environmental changes, but their general body structure has remained relatively unchanged. This remarkable evolutionary longevity makes sharks one of the most enduring creatures in Earth's history.
The Evolutionary Success of Sharks
Sharks have survived numerous mass extinctions and have continued to thrive in oceans worldwide. Their ability to adapt to different habitats and climates has made them highly successful predators. Unlike most other species, sharks’ evolutionary changes have allowed them to maintain their dominance in marine ecosystems for millions of years. Their unique biological traits, such as their keen sense of smell, electroreception abilities, and fast swimming capabilities, have ensured their survival through the ages, highlighting their evolutionary success and adaptability.
