Scientists have discovered at least two genetic pathways leading to the identical physical outcome for a species of flycatcher in the Solomon Islands.Nature often finds a way when it comes to the biological necessities of survival and reproduction. Sometimes there is more than one way. Scientists have so far identified at least two genetic pathways that result in the same physical outcome for a flycatcher species that live in the isolated Solomon Islands: all-black feathers.
“Clearly there’s something advantageous about having all-black plumage,” said Campagna. “We’ve traced this trait back through time by sequencing the entire Chestnut-bellied Flycatcher genome for the first time. The two mutations that lead to black plumage appeared at different times, on different islands, and on different genes related to melanin pigment production.
Uy has been studying the Solomon Islands flycatchers for about 15 years, aided by a trusted group of indigenous islanders he says have been “instrumental” in his work.
