 First, determine the characteristics that encompass all these animals namely :
vertebrates / spine.
 After that, what you do is eliminate one by one.
 The first ones eliminated were: fish mujahir. Why ? Because the mujahir fish are
the only animals that don't have lungs (but gills).
 So that on the second branch write: "breathe with the lungs" as dividing the second
branch.
 The remaining rabbits, cows and horses.
 Who will be eliminated next? Of course cats, because among the three animals that
do not breed only cats. So that the cat will become the second branch in the
cladogram.
 The division between the cat and the next branch is "ruminate" (ind.: memamah
biak).
 What remains are cows and horses.
 Which will be eliminated next? is something special that 1 has over the other,
between a cow and a horse.

Try to find the difference between a cow and a horse that looks and becomes its
specialty !

Yes ! cows have horns and horses don't.
So after this you can use which animal will be eliminated. If you use horns as the last
barrier then the horse will be eliminated first.

The results of the cladogram are something like this.

horse
mujahir cat cow
fish

horned

ruminate

have lungs

vertebrate

If you are presented with a cladogram and asked to read it then it is as follows :
Example : based on the cladogram above, what are the characteristics of a horse ?
So what you see is the following section.
