The astonishing evolutionary journey from walking land mammals to modern whales
Whales may be masters of the ocean today, but their ancestors once walked the earth. This video explores the fossil evidence revealing how hooved land mammals eventually traded limbs for fins.
The transition from land to sea is etched into the fossil record. An incredible trail of fossils demonstrates that modern whales are the descendants of ancient, hooved land mammals. This evolutionary shift was not instantaneous, but a complex process of adaptation.
The legacy of their terrestrial past remains visible in whales today. From the specific anatomy of their stomachs to the unique mechanics of their swimming gait, whales still carry biological fingerprints of their ancestors.
