A new study has demonstrated that as horses get bigger, their toes disappear to a single toe.
Tracing the evolutionary traces of horseshoes, the scientists first studied 13 horseshoe fossils belonging to the Hyracotherium species, about 50 million years ago. They then compared these figures with modern horse characteristics.
As the horse gets bigger and bigger, a big toe is more useful than a set of clogs with many small hooves
They analyze information such as bone lengths and body areas using 3D scanning. Thereby, they can know the bearing capacity of the bone with effects such as compressing or bending.
Next, the team estimated each horse’s body mass and calculated how much pressure each leg was under, then deduced the effects of these metrics on the ability to trot or jump. them.
