"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.

"240 Mammal Genomes Unravel Secrets of Human DNA"

The Zoonomia Project has compared DNA sequences from 240 mammalian species to identify key parts of the human genome that have remained unchanged for millions of years, shedding light on disease susceptibility and unique mammalian traits. The findings offer potential for improved disease understanding and biodiversity conservation. The researchers identified regions of the genomes that are most conserved across mammalian species and millions of years of evolution, pinpointed species that may be particularly susceptible to extinction, and identified genetic variants that are more likely to play causal roles in rare and common human diseases.
