Old-to-Modern Communication Style

People had tried to communicate since the prehistoric age. Before people knew language or even writings, people communicate to others by many chance necessary. Here's a few way to communicate in ancient times.

1. Smoke signals. This way of communicating is famous in North America and China hundreds of years ago. This was made by putting a fire on the blanket. A "pro" can manage the size of smoke and even the colours, making it easy to differentiate messages sent. Smoke signals often used for sending simple messages.
Pros : It can be seen from long distances
Cons : There's no way people will talk about their secrets using smokes


2. Drums. Informations can also be sent by sounds, as the people in West Africa used it. Messages told from the sound of drums are various and complicated. This way of communicating was also being used by slaves to send secret codes.
Pros : High frequency makes it can be heard 8 kilometres away.
Cons : It's hard for people who don't know to understand.


3. Whistle. This one is very rare. This way of communicating had been used by people on the Canary Island of La Gomera. People used to keep in touch to people on the hill or valleys. Whistles are capable of sending 4000 different words!
Pros : Effective way of calling your wife or someone in the crowd
Cons : It's secretless...



While people nowadays using many medias to communicates, animals also have their own way to communicate to each other.

1. One way that animals do to communicate by using their sense of smelling. Some animals such as ants, bees, etc. produce chemical substances called pheromones. This substance can be in their urine, or spreading from their body. Bees also use movements instead of pheromones and Ants lead their packs to the food source using food trail pheromones

2. Like us humans, animals such as birds and frogs communicate with sounds. Male frogs send 2 parts of messages. The first one is a warning and can only be heard by other male frogs, and the other is a mating call for the female ones.

3. Whales, bats, and elephants communicate with sounds that we can't hear. The frequency of their sounds are usually below 20Hz or above 20.000Hz. Their sounds produce waves that travels from ground, water, or air. Elephants probably receive signals from their trunks or feet.
