You really can't have a kid survive its mother who died in childbirth if the kid is as helpless as here.
UNLESS you have not only competition, but altruism, too.
Yes, altruism can pretty easily be part of the picture. Kin selection and all that. Or, we can simply say that if a gene makes a male mate with 2x as many females but also makes 20% of the females die with the child dying too, it still propagates. And it still increases sexual competition by unbalancing gender ratios thus if it was in itself a sexual competition advantage, now it is on the relative level stronger.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
