Question:

Ant-mimic spiders of the genus Myrmarachne are known for which one of the following evolutionary phenomena?

The Correct Option is B

Solution and Explanation

Myrmarachne spiders are well-known for their mimicry of ants. These spiders engage in aggressive mimicry, where they imitate ants in appearance and behavior in order to deceive their prey or avoid predators. This type of mimicry allows them to infiltrate ant colonies or remain unnoticed by potential predators.
[6pt] - Aposematism (Option A) is a form of warning coloration used by some organisms to indicate that they are toxic or dangerous, which is not the case for Myrmarachne.
[6pt] - Batesian mimicry (Option C) involves a harmless organism imitating a harmful one to avoid predation, which is not the case for Myrmarachne, since they do not rely on mimicking dangerous or toxic species for protection.
[6pt] - Müllerian mimicry (Option D) involves two harmful or dangerous species mimicking each other, but Myrmarachne does not fit this category.
