Two species of flies,Drosophila melanogaster and Drosophila simulans can mate. They usually do not mate, nowever, even if they are kept together in a laboratory. Males court the females of both species, but the fem prefer to mate with males of their own species. Which isolating mechanism does this describe? behavioral temporal artificial anatomical

The isolating mechanism described in this scenario is behavioral.

Explicação

## Step 1
The problem describes a situation where two species of flies, Drosophila melanogaster and Drosophila simulans, can mate, but they usually do not mate even when kept together in a laboratory. This is a case of reproductive isolation, which is a key concept in the theory of evolution.

## Step 2
Reproductive isolation is a mechanism that prevents species from interbreeding with others. This can occur in various ways, such as geographical isolation, temporal isolation, behavioral isolation, anatomical isolation, and others.

## Step 3
In this case, the flies of both species exhibit a preference for mating with males of their own species. This is a form of behavioral isolation, where the behavior of the organisms prevents them from mating with members of other species.
