Human communication was revolutionized with the origin of speech approximately 500,000 BCE. Symbols were developed about 30,000 years ago. The imperfection of speech, which nonetheless allowed easier dissemination of ideas and eventually resulted in the creation of new forms of communications, improving both the range at which people could communicate and the longevity of the information. All of those inventions were based on the key concept of the symbol.
The ability to communicate effectively with other individuals plays a critical role in the lives of all animals. Whether we are examining how moths attract a mate, ground squirrels convey information about nearby predators, or chimpanzees maintain positions in a dominance hierarchy, communication systems are involved.
Studying communication not only gives us insight into the inner worlds of animals, but also allows us to better answer important evolutionary questions. A thorough understanding of animal communication systems can also be critical for making effective decisions about conservation of threatened and endangered species. As an example, recent research has focused on understanding how human-generated noise (from cars, trains, etc) can impact communication in a variety of animals.
Don’t use words too big for the subject. Don’t say infinitely when you mean very; otherwise you’ll have no word left when you want to talk about something really infinite.~ C.S. Lewis
What we do see depends mainly on what we look for. … In the same field the farmer will notice the crop, the geologists the fossils, botanists the flowers, artists the colouring, sportmen the cover for the game. Though we may all look at the same things, it does not all follow that we should see them ~ John Lubbock (The Beauties of Nature and the Wonders of the World We Live in)
You have the ability to choose your reactions ~ Steve Maraboli ( Life, the Truth, and Being Free)
It’s a funny thing about life, once you begin to take note of the things you are grateful for, you begin to lose sight of the things that you lack ~ Germany Kent
