Din 5. A virus killed most of the blue-footed ducks in Japan reducing the population from 9,000 to 900. In an effort to help preserve the species, 50 blue-footed ducks were trapped and used to start a new population in England.Eventually the two blue-footed duck populations could no longer successfully interbreed. This event would best be described as. mutation speciation extinction convergence

## Step 1<br />The problem describes a situation where a virus drastically reduces the population of blue-footed ducks in Japan, from 9,000 to 900. This is a significant decrease in population size.<br /><br />## Step 2<br />The problem also mentions that 50 blue-footed ducks were trapped and used to start a new population in England. This is an example of a founder effect, where a small group of individuals is isolated from the rest of the population and forms a new population.<br /><br />## Step 3<br />The problem concludes by stating that the two blue-footed duck populations could no longer successfully interbreed. This indicates that the two populations have evolved to the point where they are no longer capable of producing fertile offspring together.<br /><br />## Step 4<br />The situation described above is an example of speciation. Speciation is the process by which populations evolve to become distinct species. In this case, the two populations of blue-footed ducks have evolved to the point where they are no longer capable of interbreeding, which is a key characteristic of separate species.
