When the Lоndоn undergrоund (subwаy) system wаs built in the nineteenth century, mosquitoes moved into the tunnels аnd became adapted to biting the customers and small animals that inhabit the subway system. Like people, mosquitoes can freely enter and leave through the tunnel entrances. Recently, DNA analysis and attempts to cross-breed above-ground mosquitoes with underground mosquitoes indicate that there are now two different species. The underground insects are visibly larger. Which term best describes what has happened?
