In a forest, a tree falls on a swamp and kills the worm population reducing the population by half. The remaining population is characterized by a remarkable reduction in genetic diversity. Which mechanism of evolution is exhibited here?
The mechanism of evolution that has been exhibited here is known as bottleneck effect. The fact that a sudden incident of the tree falling caused the death of rare alleles and this resulted in the decrease in genetic diversity of the population. I hope that this is the answer you were looking for and it has helped you.
