Step 1
Give one method that can be used to date a fossil of a Hipparion.
Answer
One method that can be used to date a fossil of a Hipparion is to use radiometric dating. This involves measuring the decay of radioactive isotopes within the rock layers or surrounding fossils to determine their age.
Step 2
Give one reason why scientists have concluded that the modern horse has evolved from Hipparion.
Answer
Scientists have concluded that the modern horse has evolved from Hipparion due to the similarities observed in their skeletal structures. Both possess pentadactyl limb types, indicating a common evolutionary ancestor.
