Did the ancient Egyptians/Romans/Greeks/Indigenous Americas/Chinese/Indian/etc. cultures have the concept of cuteness? Did their languages have a word for what we today describe as cute, such as baby animals, anime characters with big eyes, anything miniature compared to the normal size item, such as a miniature stapler - or maybe in those days a miniature statue or miniature axe.
Or is cuteness as we know it today a fairly modern concept?
Probably about a hundred million years before humans evolved. All animals that care extensively for their young (which includes all mammals) have instincts to respond more favorably to things that look like babies. “Cuteness” is just a human term for that instinct as it manifests in us.
