"Study Finds Butterfly Genomes Unchanged for 250 Million Years"
A study published in Nature Ecology & Evolution reveals that the genomes of butterflies and moths have remained largely unchanged for over 250 million years, providing clues to their resilience in the face of environmental changes. Researchers traced the genetic code back to the first butterflies, identifying 32 ancestral chromosomes. The study sheds light on the genetic stability of Lepidoptera, a diverse group making up 10% of living organisms, and its potential implications for biodiversity conservation efforts amidst rapid species loss.
