Scientists analysed thousands of animal genomes and found hidden “evolutionary highways” stretching back 600 million years |

Scientists have traced hidden pathways through animal evolution by comparing thousands of genomes and following pieces of chromosomes that have survived for hundreds of millions of years. The study examined 5,821 chromosome-scale genomes from 4,454 species across 19 animal phyla, using 29 ancient linkage groups as markers of chromosome history. Every one of the 406…

Scientists found that DNA once dismissed as “junk” helps chromosomes find their partners |

For years, the dense loops of repetitive DNA clustered near the middle of chromosomes were treated as evolutionary clutter. According to the new study published in Nature, titled ‘Meiotic pairing through barcode-like satellite DNA repeats‘, researchers working with fruit flies have shown that this so-called satellite DNA forms a kind of barcode: a unique combination…

Zebra mussel DNA detected in Utah’s Colorado River for first time, raising alarm over invasive species threat across the Upper Colorado River basin |

An invasive species threat has reached a new stretch of the Colorado River, after scientists detected zebra mussel DNA in Utah’s portion of the river for the first time. The discovery has raised concerns among wildlife officials because zebra mussels can spread rapidly once established, potentially damaging infrastructure, disrupting recreation and altering freshwater ecosystems. The…

In the 1800s, red foxes were brought to California for hunting. Decades later, the light-footed Ridgway’s rail declined to just 5 breeding pairs |

A red fox introduced to California more than a century ago might seem far removed from the fate of a small marsh bird. Yet the two became linked in the coastal wetlands of Southern California, where the light-footed Ridgway’s rail has struggled to survive. The bird spends much of its time concealed among cordgrass and…
