Cave evolution on repeat: reuse of the same genomic regions across lineages of Astyanax mexicanus.

It is found that genetic repeatability is a common feature in the repeated evolution of cave traits, the extent of genetic repeatability varies across cave traits, and there is little evidence for widespread colocalization of sleep, eye loss, and metabolic traits within the genome.

A pangenome framework uncovers the role of deletions in repeated evolution of cave-derived traits

The results reveal that recurrent deletion events have repeatedly contributed to the evolution of cave-adapted phenotypes and highlight deletions as underexplored contributors of adaptive evolution in a system characterized by trait loss.

A pangenome framework uncovers the role of deletions in repeated evolution of cave-derived traits.

Structural variants (SVs) are increasingly recognized as key contributors to adaptive evolution, yet they remain underexplored compared with single-nucleotide variation. To understand how large-scale genomic changes shape repeated evolution, we leveraged multiple levels of sequence data across the powerful evolutionary...
