ancient horses had more bones in their foot than present - day horses. the present - day horse has 11 foot bones. what is the correct order of evolution of the horse starting from the youngest fossil?
qprs
srpq
sqpr
rpqs

Explanation:

Step1: Understand the evolution trend

Since ancient horses had more foot - bones than present - day horses, and we are looking for the order starting from the youngest fossil (closer to present - day in evolution, fewer bones).

Step2: Compare the number of foot - bones

We have the number of foot - bones: \(P = 19\), \(Q=17\), \(R = 24\), \(S = 13\). The order of the number of bones from fewest to most is \(S(13)<Q(17)<P(19)<R(24)\)

Answer:

The correct order is \(SQPR\)
