Cuckoo Genetics Show Host Habits Alone Don't Split Species
Original: Cuckoo Genes Reveal Host Habits Alone Cannot Divide a Wandering Species
New genetic research on cuckoos indicates that differences in host preferences are not enough on their own to divide the wide-ranging birds into separate species. The findings suggest that despite specialised egg-laying habits targeting different host birds, gene flow across populations keeps the wandering species genetically unified, complicating how scientists classify parasitic cuckoo lineages.
Why now: Fresh research challenges the assumption that host specialisation drives speciation in brood-parasitic birds.
