Which creature is more closely related to ticks?

• A. Insects
• B. Spiders
• C. Crustaceans
• D. Worms

Answer: (B)

Ticks are more closely related to spiders because they both belong to the class Arachnida, which is characterized by having eight legs and a lack of antennae. This class includes arachnids such as spiders, scorpions, and mites, in addition to ticks. The morphological and genetic similarities between ticks and spiders underscore their common ancestry within this group. This relationship is significant as it places ticks in a distinct evolutionary context when compared to other animals. Insects, crustaceans, and worms belong to separate phyla that are quite distinct from arachnids. Insects are part of the phylum Arthropoda but are classified under a different class (Insecta), whereas crustaceans are also in Arthropoda but belong to a different subclass (Crustacea). Worms, on the other hand, fall under various phyla unrelated to arthropods.
