Instead, chromosome changes tend to move along a restricted set of irreversible pathways that the researchers describe as "evolutionary highways."

That irreversibility makes such chromosome changes especially useful for reconstructing evolutionary history.

Occasionally, however, something goes wrong during division, leaving cells with an abnormal number of chromosomes.

During this evolutionary upheaval, large sections of genetic material were rearranged, bringing regions of chromosomes that had previously been separated into close proximity.

Chromosome-scale assemblies provide much more detail by arranging genes in their proper order across complete chromosomes.

Since that time, chromosomes have repeatedly fused, separated, and been rearranged as new animal lineages emerged.
