Answer explanation
The newt population became more poisonous because the snakes in this environment caused poison to be an adaptive trait. When snakes became part of the environment, the newts with high-poison level were more likely to survive. Over time, newts with a high poison level became more common in the population because they were more likely to survive after the environment changed.
