How many times is the modern horse taller than its earliest ancestor? Show your working.

2.2.1) Step 1: Identify the height of the modern horse and its earliest ancestor from the diagram. The modern horse (Equus) has a height of 1.6 m. The earliest ancestor (Hyracotherium) has a height of 0.4 m. Step 2: Calculate how many times taller the modern horse is by dividing its height by the ancestor's height. Height of modern horseHeight of earliest ancestor = 1.6 m0.4 m Step 3: Perform the division. (1.6)/(0.4) = 4 The modern horse is 4 times taller than its earliest ancestor. 2.2.2) Over time, the number of toes on the horse's front leg reduced from multiple toes to a single, central toe that developed into a hoof. The leg also became longer and more adapted for running. 2.2.3) One way the modern horse is adapted to open grassland is the development of a single hoof on each foot. This adaptation allows for greater speed and efficiency when running on hard, open ground, which is crucial for escaping predators in a grassland environment. Send me the next one 📸
