How did a rhino evolve?

Rhinos evolved from early hoofed mammals known as perissodactyls, which also include horses and tapirs. Their evolution began around 50 million years ago, adapting to diverse environments and developing traits suited for grazing and browsing, such as thick skin and large body size. Over time, rhinos diversified into several species, with their adaptations allowing them to thrive in various habitats, from grasslands to forests. Today, they are characterized by their distinctive horns, which are made of keratin and have evolved for social and defensive purposes.
