Our planet has millions of species. Over 300,000 beetles alone. 17,000 butterflies. Thousands of mammals, fish and birds, all astonishingly different. How did so many species come to be ? To seek insights into that question, researchers are focusing on places where species recently arose, such as the remote เกาะกาลาปากอส
Carrol : scientists are making observations and conducting experiments that would have surprised ชาร์ล ดาร์วิน . And they’re discovering new insights into what the great naturalist called the “mystery of mysteries”. How new species from.
