The table shows the number of nails on the front feet of elephant species. Elephant species Number of nails on front feet African forest elephant 5 African savanna elephant 4 Asian elephant 5 Explain why this data shows discontinuous variation.

Different species of elephants show different features. Each elephant is adapted to its surrounding environment.Like African elephants have big ears and dry skin. Whereas Asian elephants have hair on their skin and much smaller nails. The data shows the number of nails in different species of elephants. Each species of elephants has different number of nails in their feet. This is discontinuous variation because there are only a limited number of possibilities present. That is why it is considered as discontinuous variation.
