-Easier birth control: Make the egg into an omelette
-Relaxed child support laws: Requires deliberate decision to incubate the egg
-Clean packaged periods: Egg = No mess!
Although, there would be stories about partners hiding fertilized eggs: Instead of unplanned parenthood we would have unconsensual parenthood
There’s probably more nuances I am missing. But do discuss it in the comments.
Ever raise chicks? It’s very informative of what egglaying requires.
Keep in mind the animals that lay eggs have a type of body that can sit and incubate and often it requires both parents to sit.
Additionally sit- Incubating this way is super inefficient and means you have to sit in one place to keep a constant temperature as opposed to our current strapped on method which means the child is constantly incubated in an ideal environment leaving the parent free to do things like keep a job to support child/hunt for food.
It has the best means for survival as you don’t end up leaving your embryo to be snatched or crushed.
And usually if your holding a child you’re also supplying milk which means the parent only has to look after feeding themselves traditionally while supplying milk which is far more readily available vitamins for the baby.
If anything you have to be much more dedicated with your time and intention and worry to be an egg layer.
Yes, my parents used to have chickens. It’s unlikely that the incubation period would be 9 months and being oviparous has It’s own challenges. If humans did evolve that route I’d imagine that we’d have overcome most of the issues. Dinosaurs being one example, it’s possible humans would be cold blooded and have learned the joy of regurgitation. It comes down to speculation whether human like intelligence could have evolved with these limitations.
Hasn’t it been discovered that dinosaurs were largely warm blooded like the birds they evolved into?
The more you know. So it could be more likely that humans sat on their eggs to keep them warm, or they would have been limited to tropical climates. Humans would have evolved very differently regardless.
