Our new paper in Science Advances asks how animals' genomes have changed since their origin from a common ancestor over 600 million years ago, and what patterns in their DNA have arisen in the churn of speciation and extinction. www.science.org/doi/10.1126/...
Five-panel diagram explaining fusion-with-mixing in chromosome evolution. Red and blue represent two different ancestral chromosomes throughout.

A, Fusion-with-mixing: a red chromosome and a blue chromosome fuse into one half-red, half-blue bar. Down the page, successive rows show inversions, drawn as X-shaped crossings between rows, progressively interleaving the two colors until the bottom bar is finely striped. A widening gray wedge labeled Entropy runs alongside an arrow marked Time plus evolution, pointing down.

B, Independent regulation: two separate chromosomes, one red and one blue. In each, a regulatory element, drawn as an oval, acts by an arrow on a gene within its own chromosome only.

C, FWM and novel regulation: on a fused, mixed chromosome, a red gene and a blue gene now sit next to each other across an inversion breakpoint. Red and blue arrows show regulatory elements reaching across it to act on the other chromosome's gene.

D, Regulatory entanglement: an extensively mixed chromosome, finely striped. Below it, a row of alternating red and blue genes is linked by a dense web of crossing curved arrows, so many overlapping regulatory connections that unmixing the chromosome would break them.

E, Emergence of entangled loci: a five-species phylogeny. A red and a blue chromosome fuse at an ancestral node, and helical icons on later branches mark continued mixing. Colored boxes mark four new red-blue regulatory interactions arising after inversions. Species A keeps its two chromosomes separate. In species B through E, the two earliest interactions, cyan boxes 1 and 2, are present in every descendant lineage, while later ones, yellow 3 and magenta 4, appear in fewer.
