Research uncovers genes behind vibrant colors in parrots and finches

Recent studies have revealed how parrots and finches develop their vibrant colors, highlighting ongoing evolutionary processes. Parrots produce unique pigments called psittacofulvins, while finches rely on carotenoids from their diet. Research identified key genes and enzymes responsible for color variation. In parrots, the enzyme ALDH3A2 influences feather color by converting red pigments to yellow. In long-tailed finches, two genes, CYP2J19 and TTC39B, control the transformation of yellow carotenoids into red bill colors. These findings show that small genetic changes can significantly impact color, suggesting evolution is a continuous process. Protecting genetic diversity is essential for conserving species and supporting future evolutionary developments.
