Chambered nautilus study
Photo of a painting of a chambered nautilus in green-blue water. The nautilus is dark red, pale orange and white with blue shadows. The shell is striped, counter shaded so it's darker on top and lighter on the bottom. The painting rests on a wood table, and a paintbrush is visible in the upper left corner.

Ants were thought to eat this parasitic plant's fruit, but cameras revealed hermit crabs as the culprits! Each crab carried off 86 fruits on average, helping spread the seeds. Its ripe scent attracts crabs and the cockroaches that pollinate it! 🧪 esajournals.onlinelibrary.wiley.com/doi/10.1002/...
A land hermit crab (Coenobita brevimanus) scrapes off the tiny (3mm) fruits of a fungus root (Balanophora fungosa). As it feeds, it picks up the plant's minuscule seeds that can travel on its claws, body, and shell!

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.
