ELI5:Do other species commit suicide? why or why not?
gpt
Yes, there are other species that do commit 'suicide', or rather engage in behavior that will likely result in its demise. Rarely its at their own hands, rather an act that gets them killed by something else.

For example, there are spider species that, during the mating process, the male will impale himself on the female's fang. By sacrificing himself, the female is more likely to allow the copulation to finish, thus ensuring that his genes pass on to the next generation.
