Age clock may track development in wild Soay sheep

Models built from body measurements collected from 1985 to 2024 linked higher predicted ages relative to actual age with better winter survival in adult sheep.Models built from body measurements collected from 1985 to 2024 linked higher predicted ages relative to actual age with better winter survival in adult sheep.
