Как всего лишь один апельсин может принести счастье)⁠⁠

Объясните, нахуя рядом с эмодзи МУЖИКА пожимающего плечами еще и символ мужского начала добавлять?

Так улыбка свойственна и другим приматам, и вообще, в целом, другим животным. Статью посмотри, но если продолжить копипасту:

То же самое, вероятно, справедливо и для собак. Неожиданно, но почти точно, смеются крысы!

В общем, теми тремя видами список не ограничен.

Как у вас получилось использовать не и ни одновременно в одном выражении?

А четвертое.

Низшие приматы - это лемуры. Макаки относятся к высшим

Макака фоткала и в кадр не попала.

Ну, именно там - нет. Но в принципе, это свойственно всем приматам.

Если верить книге Алана Писа (https://en.wikipedia.org/wiki/Allan_Pease), эксперта по языку тела, то улыбаются они так:

Smiling and laughing are universally considered to be signals that show a person is happy. We cry at birth, begin smiling at five weeks and laughing starts between the fourth and fifth months. Babies quickly learn that crying gets our attention -

and that smiling keeps us there. Recent research with our closest primate cousins, the chimpanzees, has shown that smiling serves an even deeper, more primitive purpose.

To show they're aggressive, apes bare their lower fangs, warning that they can bite. Humans do exactly the same thing when they become aggressive by dropping or thrusting forward the lower lip because its main function is as a sheath to conceal the lower teeth. Chimpanzees have two types of smiles: one is an appeasement face, where one chimp shows submission to a dominant other. In this chimp smile - known

as a 'fear face' - the lower jaw opens to expose the teeth and the corners of the mouth are pulled back and down, and this resembles the human smile.

The other is a 'play face' where the teeth are exposed, the corners of the mouth and the eyes are drawn upwards and vocal sounds are made, similar to that of human laughing. In both cases, these smiles are used as submission gestures. The first communicates 'I am not a threat because, as you can see, I'm fearful of you' and the other says 'I am not a threat because, as you can see, I'm just like a playful child'. This is the same face pulled by a chimpanzee that is anxious or fearful that it may be attacked or injured by others. The zygomatics pull the corners of the mouth back horizontally or downwards and the orbicularis eye muscles don't move. And it's the same nervous smile used by a person who steps onto a busy road and almost gets killed by a bus. Because it's a fear reaction, they smile and say, 'Gee...I almost got killed!'

В разговорном языке допускаются оба варианта.
100 лет назад ваще говорили и писали "оранг".

Нет, у животных так не принято. Там все сложнее чем "Отдал мне еду - слабее меня"
