Fish Migration and MOVA Globes

David from MinuteEarth explores how a trout ended up in an isolated alpine lake. He rules out the fish walking or evolving there and considers three main possibilities: rain overflow creating temporary streams, human intervention through air-dropping fish, and natural dispersal by animals like ducks. Ducks can transport fish eggs over long distances, leading to fish appearing in remote lakes. The video concludes with a promotion for MOVA globes, which are decorative spinning globes powered by ambient light.
