That’s right Apeiron.
Sorry , I don’t get it .
Even if deva/devi together think(liking)of each other and spontaneously give birth to a child is not considered biological ?!
There’s probably too much into sensual pleasures to go through childbirth and bringing up children

The suttas don’t really say anything about this.
It’s important to remember that while the basic teachings on rebirth are found in the central teachings like the four noble truths and dependent origination, they don’t really say much about all the different realms and so on. Most of what we learn about that is from narratives and verses, which often are from a later strata of the texts, and are infused with culturally bound ideas from Indian tradition. And even then, there’s still not all that much.
So there’s really little that we can say about many of these questions, at least so far as what is found in the early texts.
