A genetic study debunks the myth that the London Underground mosquito evolved in WWII-era subways, showing it originated 2,000–3,000 years ago in the Mediterranean and Middle East.
A new genetic study reveals the "London Underground mosquito" did not evolve in the city's subway system during WWII, as long believed.
Researchers analyzed DNA from over 800 mosquitoes worldwide, including historical specimens, and found the species originated in the Mediterranean and Middle East 2,000 to 3,000 years ago.
It evolved from bird-biting mosquitoes in arid regions with irrigation, adapting to human environments before spreading north.
The insect only moved underground in colder climates to survive winter, with first underground sightings in northern Europe around 1920.
The findings, published in Science, dispel a longstanding scientific myth and highlight how human activity shaped its global spread.
Un estudio genético desmiente el mito de que el mosquito del metro de Londres evolucionó en los subterráneos de la Segunda Guerra Mundial, mostrando que se originó hace entre 2.000 y 3.000 años en el Mediterráneo y el Medio Oriente.
