Ok, so there are some creatures in the world that have spikes on them or a poisonous slime that keep predators away. How did these natural protections form in the evolutionary prospective? Wouldn't a speicies die without the protection before it could gain a trait like this?
Also, lets take strawberries as an example for my next point. This fruit has no natural protection, yet it is constantly eaten by its "predators". Why has this fruit, or any other common ones, not formed protection to keep it safe?
