did the human heart evolve through the ages?

Yes, the human heart has evolved over millions of years, reflecting changes in environmental demands and physiological needs. Early vertebrates had simpler heart structures, while the evolution of mammals led to the development of a four-chambered heart, which allows for more efficient circulation. This adaptation supports higher metabolic rates and the demands of a more active lifestyle. Overall, the heart's evolution is a key factor in the adaptability and survival of species.
