On the lighter side of things: penguins

There are so many traits about penguins that are awesome. They bond for life. They propose using stones. They adopt children. They have same-sex families. They know about community and solidarity. They are wonderful creatures. They are also wonderfully stupid sometimes, you can literally have the blind lead the blind if you do it right. Nonetheless I love these little beasts! Which is why I was so stoked when I came across this article from I f****** love science:

......I was hooked. And you know you are too! Who doesn't want to know reasons that penguins are kind of like humans when it comes to communication? I mean really? It's definitely fascinating! Verbal languages crude as it is but it's nice to know we aren't the only animals that use it on Earth. Anyways, I'm rambling, continue reading for more info.

To discover this they studied the display calls of 28 adult African penguins – knowns as jackass penguins due to their donkey-like bray rather than their tendency to be a jerk – in three colonies in Italian zoos.

They collected and analyzed 590 “ecstatic display songs” (their words, not mine) during the 2016-2017 breeding season. These calls, usually uttered by males, signify their suitability as a mate, claim territory by warning off usurpers, and identify themselves as individuals to their comrades.

So basically Penguin language is evolving in a way similar to human's they get tired of saying the same stuff so they find ways to say it faster, IE.......slang..... like how we have cray for crazy and so on.... It is kind of neat. READ THE SOURCE HERE <----IFLS up in the hizzy

 known as Zipf’s Law of Brevity postulates that the more frequently a word is used, the shorter it will be, and vice versa. This can be found in languages around the globe – yes and no are good examples, as are warning words like help, or fire. It’s thought information compression is a general rule that applies to all human language, due to selective pressures to communicate accurately but efficiently.

While that may not seem like a big deal....IT IS. I mean, it isn't that unnatural for OTHER primates to follow these kind of speech patterns the peculator part is that this has NOT EVER been witnessed outside our fury ass ORDER on the tree of life, aka our descendants...aka PRIMATES. So that's kind of cool if you ask me. I'll bet in the coming thousand years we will see a significant evolution in animals as far as spatial intelligence and cognition go, it'll be easier for them now that humans have started taking the planetary role of caretaker for seriously

Researchers studying the display songs of African penguins in captivity found that penguins communicate in the most efficient way using shorter sounds for the “words” they use most often and longer vocalizations with more syllables for more complex messages – both of which adhere to two linguistic principles found in human speech around the world.
