is it bad for the mother wolf to consume her offspring?
Technically, there is nothing wrong in the mother wolf eating her offspring, as long as it can act as an energy source. But once again, you have to think in terms of software and survival of the species.
The job of love is not only to bind the mother to the child. I believe it is to survive the species. Now if there was no such software, then yes, it is likely the mother can consume her offspring. But this does not happen that often. Well, it happens only in exceptional circumstances: for e.g., when food supply is scarce. In such situations the mother might be compelled to make a meal out of her offspring.
But otherwise, this event is unlikely. Why? Again because of the phenomenon called love. Now if there were no such software called love, then what do you think might be likely to happen? The mother eating the child – or cannibalism.
And cannibalism was a popular phenomenon in the days of prehistory. But then is it relevant today? Well, you might hear of small isolated cases, but they are not frequent. But then how do you explain why the phenomenon of cannibalism disappeared? Well, if you think of cannibalism to be the source of major diet of the wolf then naturally the species of wolves might turn out extinct. That’s why!
But then again, how is all this related to love? Love binds. In a society group where there were males and females, it was usually the females who reared the child. And sometimes it was possible that males consumed offspring of their own descent. So the females not only had to rear the child to maturity, it also had to protect it from other males. And love was software that supported this activity in someway.
