I’m writing a humanoid race with perfectly symmetrical bilateral anatomy. This trait is shared by almost all complex life on their world and has shaped the way they reproduce; via mitosis. I’ve already solved how this works so no need to criticise the concept (just assume it works), **but what really really interests me in this question is how this change in biology affects the cultural development of a species. How different would their worldview be from ours?**

**Biology:** Human organs are asymmetrical but theirs perfectly mirror the other side. They have at least two of each organ. Because they are sexless they have no genitals or dimorphism between males and females nor do they have nipples and bellybuttons. Since they procreate by fission their reproductive organ could be considered to be the thin line that separates their two halves. Reproduction is involuntary and regulated by hormones. Once the time comes they must eat to grow then they split apart into two fully functioning adults (new organs grow in the midsection like a caterpillar as a chrysalis). Each new half isn’t identical, genes randomize traits to get diversity without a partner. There’s always one half older than the other but since they reproduce like cells they are biologically immortal, they just split every once in a while (which could be considered an individuals lifespan). Disease, malformations and injuries which would hamper their ability to split would be the same as a womb being damaged. Individuals who can’t recover don’t split (infertile).

Edit: They're born adults. They remember everything as information is shared between halves. They reproduce yearly when isolated, when population density increases their reproduction slows down proportionally, at most to once a decade. They can distinguish individuals like twins can. They are omnivores like us. They live in houses like us. Infertile individuals can live to forty years old. If they don't eat the splitting stops or they starve.

**I ask again: how does this affect their cultures development?**
