Question
Which situation would most likely lead to allopatric speciation?Question 6Select one:a.A flood causes the formation of a new lake.b.A storm causes several large trees to fall down.c.A mutation causes a new trait to develop.d.An injury causes an organism to seek out a new food source.
Solution
The situation that would most likely lead to allopatric speciation is "a. A flood causes the formation of a new lake."
Allopatric speciation is a mode of speciation that occurs when biological populations of the same species become vicariant, or isolated from each other to an extent that prevents or interferes with genetic interchange. This can be caused by physically separated habitats.
In the case of a flood causing the formation of a new lake, a population could be divided by this new body of water. Over time, the two separated populations might evolve differently and eventually become two different species. This is a classic example of allopatric speciation.
The other options (b, c, and d) do not necessarily lead to the physical separation of populations, which is key in allopatric speciation.
