In an area in Africa, temporary pools form where rivers flow during the rainy months. Some fish have developed the ability to us
Law Incorporation [45]

Answer:

The preferable option will be - 1.

1. The fish using ventral fins as "feet" will be present in increasing numbers.

Explanation:

After many years, the fish who are using ventral fins as "feet" will be present in increasing numbers because -

We know that

  • These pools are temporary pools made up of rainwater. These pools do not last for longer times.
  • Some fish have developed their ability to use their ventral fin as feet and can travel from one temporary pool to others.
  • So, after many years, more and more fish will develop that ability to survive.
  • As we all know about "the survival of the fittest" theory so some of them won't be able to make it.
  • To develop their ventral fin as their real feet will take thousands of years and some genetic modification. So, that won't happen in many years.
