What to know about Animal genomes follow irreversible 'evolutionary highways' across thousands of species

Researchers from the University of Vienna have developed a new framework called 'evolutionary genome topology' to map the chromosomal evolution of over 4,000 animal species. The study suggests that animal genomes evolve along irreversible paths, or 'evolutionary highways,' which can help scientists identify distinctive lineages and inform biodiversity conservation.

What happened

Animal genomes follow irreversible 'evolutionary highways' across thousands of species Sadie Harley Scientific Editor Robert Egan Senior Editor A human, an octopus, and a coral could hardly look more different—yet deep inside their cells, their chromosomes…

Why it matters

Since then, their chromosomes have fused, split and rearranged countless times.

Common ground

Today, thousands of animal genomes have been sequenced.

Perspective signals

Claim 1: “At the heart of these patterns is a process the team named "fusion-with-mixing" in an earlier study: When two chromosomes fuse, their genes intermingle in a way that cannot be undone”
CORROBORATED
Multiple sources confirm the 'fusion-with-mixing' process, describing it as the irreversible intermingling of genes when two chromosomes fuse.
