Genetic studies consistently classify the Eastern wolf as a distinct species, separate from both the gray wolf and the coyote.
Answer: False
Explanation: The taxonomic status of the Eastern wolf is a subject of ongoing debate among scientists. While some studies suggest it is a distinct species, others indicate significant genetic admixture with gray wolves and coyotes, leading to differing classifications.
The prevailing scientific consensus is that the Eastern wolf is a pure lineage with no genetic contribution from other wolf or coyote species.
Answer: False
Explanation: The prevailing scientific view acknowledges significant genetic admixture in the Eastern wolf, primarily from gray wolves and coyotes, which complicates its classification as a pure lineage.
The American Society of Mammalogists currently classifies the Eastern wolf as a subspecies of the gray wolf (*Canis lupus*).
Answer: False
Explanation: As of 2021, the American Society of Mammalogists recognizes the Eastern wolf as its own distinct species, *Canis lycaon*, rather than a subspecies of the gray wolf.
What is the primary reason cited for the debated taxonomic status of the Eastern wolf?
Answer: Its significant genetic admixture with coyotes.
Explanation: The primary factor contributing to the debate surrounding the Eastern wolf's taxonomic status is its significant genetic admixture with coyotes, alongside gray wolf contributions.
