Washoe est la premiÃ¨re chimpanzÃ© ayant appris Ã communiquer grÃ¢ce Ã la langue des signes :
Washoe greeted Kat [the caretaker] in just this way when she finally returned to work with the chimps. Kat made her apologies to Washoe, then decided to tell her the truth, signing « MY BABY DIED. » Washoe stared at her, then looked down. She finally peered into Kat’s eyes again and carefully signed « CRY », touching her cheek and drawing her finger down the path a tear would make on a human. (Chimpanzees don’t shed tears.) Kat later remarked that that one sign told her more about Washoe and her mental capabilities than all her longer, grammatically perfect sentences.

Les nÃ©matodes parlent entre eux avec des molÃ©cules chimiques :
For example, the researchers found several molecules that tell nematodes to scatter and disperse. These molecules consist of only two building blocks. But adding a third building block called an indole changes the meaning completely: instead of « go away » the message becomes « everybody come here. » Nematode messages get even more complex by combining two or more different molecules, just like combining different words in a sentence makes for more complex meaning.
Les perroquets sauvages apprennent leur nom en Ã©coutant leurs parents :
But what parrots can do is they can say: « Eh Tom, wanna go get some food? I’m Bob. » And that’s pretty amazing.
