What do breed groups like the Terrier Group reflect, contrasting with Linnaean taxonomy?
Answer
Concentrated results of human-directed evolution
Breed groups, such as the Terrier Group, primarily reflect the concentrated results of human-directed evolution, often referred to as artificial selection, imposed over the last few centuries. This is distinct from Linnaean taxonomy, which describes shared ancestry based on natural evolution and biological relationships across vast timescales. For the Wheaten Terrier, selection pressure favored traits like gameness and alertness suitable for bolting badgers or foxes, demonstrating how human intervention sculpts specific functional characteristics within the shared *Canis lupus familiaris* species.
