Scientist from McGill University believed that they had discovered guppies that could adapt to heavily oil-polluted oil environments in Trinidad.
What these scientist actually found was these guppies are not adapting to their environment. The scientist were surprised to find that their assumptions were wrong because the guppies seemed to be surviving just fine and are known to adapt quickly.
The world’s ecosystem is changing quickly due to high stress that mankind is putting on the environment. If fish were able to adapt or survive in water that is highly polluted by oil it would be very beneficial.
The guppies didn’t adapt but are instead “running away” from their competitors and predators. The guppies can survive in the oil-polluted environment much better than their predators and competition.
