Human beings, when in a group tend to work together to attain their objective. This hasn't changed throughout the centuries. When faced with a common goal or adversity, they put aside their differences and work together. Even when there is nothing in common between people, they tend to find ways to co-operate. Humans are good at organising and planning, and hence they're effective at what they do. The organisational skills have improved considerably over the years, due to the development of languages, and modes of communication. They tend to make the most of the available resources.
>What do you learn from this comparison of tools now and then?
The tools required for any particular task are readily available today. One probably already owns it, or can easily get them from the store. In ancient times, man had to make use of what was available in nature to do his job. For example, to make a fire in order to prepare his meal, man had to find stones and dry wood. Nowadays, one can use match sticks, flares, stoves, ovens, micro wave ovens, and other facilities to prepare his meal. However, as technology has advanced, so has man's dependence on technology. In today's world, one cannot survive without a mobile phone, cash, watch, and other things. Technology, has made man closer to people all around the world. One can speak to a person all across the world by just dialing a number, which takes mere seconds. Something that was unthinkable just a couple of centuries back.
>What you learn from this comparison about human communication?
Human beings have always had the urge to communicate, whether to convey messages or to pass on ideas. While in the case of cave-men, they were restricted to body language, and hand movements to communicate, nowadays, there are many modes of communication. The advent of languages has improved communication by leaps and bounds. People knowing a common language can easily converse. Then came the problem, of people from different regions communicating, as they each had their own language. Ever since English has been adopted as a common language throughout the world, communication has vastly improved. With the growth in technology, man has ways to communicate, other than just speaking. Telephone, telegraph, mobile phones, letters, email, chats, video conferences, have just made communication more and more easier.
>What do you learn from this comparison about cultural change and innovation?
Civilisations have played a huge role in making humans what they are now. In ancient times, human behaviour was quite similar to that of animals. Men had just basic needs, to find food and to rest. Then, as years went by, man slowly but steadily learned how to use nature's gifts to his own advantage. From the stone age, to metal age, to today's technological age, man has expanded his horizons in such a manner that nothing is out of his grasp. Civilisation and culture were important in man's growth. Without records of earlier civilisations, man would probably have advanced a lot slower. Technological innovations have completely transformed the way man lives today. The need to innovate has always been there in humans. From eating raw meat, to learning how to build fires and cook, to building sky-scrapers and traveling to the moon, man has been innovating in order to make his life more easier and comfortable.
