Most scientific questions are based off of theory.
Some individuals are more likely to survive and reproduce than others because they are fit and easily adapting. This idea is called 'survival of the fittest'.
Ungulate refers to the large, diverse group of mammals which use the tip of their toes to support their whole body weight while moving. They are divided into two, which are odd toe and even toe ungulates.
Even toe ungulates are those mammals whose weight are supported equally by their third and fourth toes while they are moving. Examples of such animals are cattle, pig, giraffe, camel, etc.<span />
