Thanks for the read. Its utterly bizarre to hear the math of it All this points to orphaned octopus babies having an advantage over those with living parents, which is easy enough to fathom. Without mom and dad around, the kids are left with more food and territory for themselves. However I’m still confused. Wouldn’t a given gene be more likely to replicate itself residing in an individual that reproduced multiple times in addition to being in half the octopus babies it helped produce? How does a gene that a parent only passes down (typically) once that inhibits survival after mating outlive a mutation that doesn't?
