Question

Evolution of horse from Hyracotherium involved

• A. Lengthening of limbs and increase in size
• B. Progressive loss of digits and . lengthening of retained digits causing shifting of soft footed to paddle footed
• C. Increased complexity of molars and molarisation of premolars
• D. All the above

Answer 1

The correct option is D All the above

Hyracotherium was a shape near the regular family of all the odd-toed hoofed warm-blooded animals, the perissodactyls. It stood 30– 60 cm (1– 2 feet) high at the shoulder, contingent upon the species. The skull differed long; a few species had a moderately short face, however, in others the face was long and more horselike. Since the rear legs were longer than the forelegs, Hyracotherium was adjusted to running and most likely depended intensely on racing to escape predators. The body was delicately built and raised well off the ground, its slim appendages upheld by toes held in a relatively vertical position.

So, the correct option is 'All the above'.
