Description
Felipe Lagreca Bitencourt and ten co-authors map the repetitive DNA of barn owls and their kin. Their 2026 study gives the first chromosome portrait of the American barn owl. Owl family members carry more chromosomes than the bird ancestor likely had, which hints at past chromosome splits.
The American barn owl has 92 chromosomes, nearly the same layout as its western cousin. Yet the two differ in their satellite DNA, stretches of repeated code. The team found eight repeat families in one species, nine in the other, and 28 in a third relative. Some families are shared, others unique to one species. The pattern fits the idea that repeats evolve from a shared library.
