It’s because of specific things, but in short it's how culture meets evolution.
Probably what you are referring to is some Asian women have legs that appear curved or bowed due to a condition called genu varum.
This happens when the knees stay apart even when the feet and ankles are together.
This is likely an issue of genetics over time.
Leg curvature can result from cultural practices, like sitting positions that may influence leg alignment over time. Sitting in a kneeling position for long periods can contribute to slight outward curvature in the legs.
Asians often eat while kneeled, in fact they do various tasks while kneeled down compared to western women.
Especially the women, and nowadays in some street corners even men in Thailand.
So over time evolution kicked in.
Now in Asia there are operations that you can have as Asia becomes more westernized more of them don't want this condition.
sounds kinda lit
