The thing with evolution is that some members of a species might have a feature that allows them to produce more offspring or live longer or something. Let's say we have some animals. Some of the animals have better immune systems than others of their species. So some of the animals with weaker immune systems will naturally die before they have the chance to produce offspring, so we end up having more animals with strong immune systems producing offspring than those with weaker immune systems. The babies have a tendency to inherit traits like strong immune systems from their parents, so we'll end up with stronger and stronger immune systems.
