What are the key differences between domestic cats and their closest wild relatives?

Judge: Accurate and comprehensive. Correctly identifies Felis silvestris lybica as the closest wild relative. Covers all four expected topics: ancestry, behavioral differences (sociality, vocalization, neoteny), physical differences (coat, size, facial features), and genetics. Well-organized with clear categories. Mentions the Taqpep gene and semi-domesticated status.

Judge: Comprehensive and accurate coverage of domestic vs wild cat differences. Correctly identifies Felis lybica as closest relative with ~10,000 year domestication timeline. Covers all four expected topics: ancestry, timeline, behavioral differences (sociality, vocalization), and physical differences (neoteny, brain size, coat diversity). Includes a comparison chart and mentions other close relatives. Minor point: some claims about brain/amygdala reduction are stated with more certainty than the research supports, but overall accuracy is strong.

Judge: Correctly identifies Felis lybica as the closest wild relative. Covers physical, behavioral, reproductive, and dietary differences with reasonable accuracy. The brain size reduction claim (25%) is in the right ballpark. Minor imprecision: wildcat weight range is a bit broad, and some domestic cat facts are generalizations. Well-organized with clear categories. Good coverage of all expected topics.

Judge: Comprehensive coverage of genetics, morphology, behavior, reproduction, and ecology. Mostly accurate with good depth. However, the hard constraint requires mentioning the African wildcat (Felis lybica or Felis silvestris lybica) as the closest relative -- the response mentions 'Felis silvestris and its subspecies' and 'Near Eastern wildcats' but never specifically names Felis lybica.

Judge: Correctly identifies Felis lybica as the closest wild relative. Covers physical, behavioral, reproductive, and neurological differences with reasonable accuracy. The claim about smaller brains is correct, the vocalization point about retained kitten meowing is well-known science. Missing explicit domestication timeline (~10,000 years ago). Well-organized with clear headers.

Judge: Correctly identifies African wildcat (Felis lybica) as the closest relative, meeting the hard constraint. Covers behavioral, physical, genetic, and dietary differences with reasonable accuracy. The 95-99% DNA claim is reasonable, and mentions of specific domestication genetics (taming genes, neurotransmitter pathways) add depth. Well-organized but somewhat verbose. Response is truncated but covers the core topics.

Judge: Correctly identifies Felis silvestris lybica as the primary ancestor. Covers behavioral, physical, social, and reproductive differences well. Misses the domestication timeline detail (doesn't mention ~10,000 years ago in the Fertile Crescent). Some claims are slightly imprecise (wild cats don't necessarily have 'proportionally larger ears'). Well-organized.

Judge: Correctly identifies African wildcat (Felis lybica) as the closest relative and covers behavioral, physical, dietary, and social differences comprehensively. Mostly accurate with well-organized presentation, though missing specific domestication timeline details.

Judge: Correctly identifies Felis silvestris lybica as the closest wild relative and mentions the 9,500-year timeline. However, the content is somewhat shallow -- differences listed (coat color, grooming habits) are superficial rather than substantive. Misses key biological differences like retractable claws, nocturnal vision adaptations, and the limited genetic divergence. The 'grooming habits' point is about human behavior, not cat biology.
