Question

Biologist: Species with broad geographic ranges probably tend to endure longer than species with narrow ranges. The broader a species’ range, the more likely that species is to survive the extinction of populations in a few areas. Therefore, it is likely that the proportion of species with broad ranges tends to gradually increase with time.

Answer 1

Assume: The question that has been asked is that " The biologist's conclusion follows logically from the above if which of the following is assumed? "

Explanation:

The characteristics that will help in the survival of the organisms will increase over the period of time.

The characteristics help the species endure longer then the other species which does not have these characters.

As the survival rate of the species having more endurance is more there is a less chance of their extinction.

So, the species having more fittest and survival favoring characters will survive more.
