The first people

Module 14

The development of the first people

Early people developed through different stages. We'll be studying four such stages.

Source 1

Different stages of early man.

Source 3

Each of the above stages is explained below.

a) Australopithecus

The oldest bones that have been discovered are those of Australopithecus . They belong to beings that lived between three and two million years ago and their bones have only been found in South and East Africa. The implements that these early people used probably were stones that they simply picked up. They walked erect and therefore had their hands free. They also used implements made of sticks, leaves and bark. They probably ate mainly vegetable foods.

b) Homo Habilis

Homo ”Habilis” had a brain that was 50% larger than that of Australopithecus – which is why “homo” (man) is added to the name.

The name Homo Habilis implies that they were handy people, because they were the makers of the first stone implements. They mainly lived in the eastern parts of Central Africa, from 2 million years ago to 1,7 million years ago. They produced various stone tools and probably also built stone walls. They also ate much meat. They probably followed a semi-nomadic way of life, living in an area for a while and then moving away to another in search of food.

The world was a dangerous place for them: they were smaller and weaker than the bloodthirsty animals in their surroundings; they did not have claws or fangs; and they could not run as well as the animals. They mostly had to run to the nearest tree to escape danger.

Homo Habilis gradually disappeared from the face of the earth with the passing of time.

c) Homo Erectus

Homo Habilis was succeeded by Homo Erectus , whose bone structure was approximately 25% bigger than that of Homo Habilis . Homo Erectus lived in Southern Africa between 1,7 million and 500 000 years ago. Archaeologists believe that they were able to communicate. They also made stone implements for cutting meat and plant foods and for making sharp tools. They were able to work with wood and discovered how to make fires. They probably used fire to corner animals to kill them for food. They also lived in cave shelters.

Homo Erectus had large teeth, a powerful jaw and a small brain cavity. Their general height was in the region of 1,5 m. As they lived in caves and could use fire, their lives were probably more secure than the lives of their predecessors. With their improved weapons they could even hunt much larger animals like rhinoceroses.

Australopethicus , Homo Habilis and Homo Erectus , of course, are not found any more.

d) Homo Sapiens

Homo Sapiens (which means “wise man”) lived in Africa from 400 000 years ago. These people were just like the modern people that occur all over the world. They had smaller teeth, a narrower jawbone and a better-defined chin. They generally did not follow a nomadic lifestyle.

All the earliest people made use of stones!

Animal skins were sewn together with the use of needles made of bone.

The skins of wild animals were stripped off the animal carcasses, scraped clean and treated to be used as clothing and as coverings for shelters, and as bags for storage.

Activity 1:

To analyse different periods with the help of a variety of sources

[lo 2.3]

  • Work in pairs and design and produce a folded booklet for an exhibition to be put up in the class.
  • Compare early people according to different criteria, e.g. with reference to the period in which they were living, the objects they used, implements manufactured by them, their lifestyle, etc.

how to know photocatalytic properties of tio2 nanoparticles...what to do now
Akash Reply
it is a goid question and i want to know the answer as well

Do somebody tell me a best nano engineering book for beginners?
s. Reply
what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
