What is the bronze and iron age?

 

What is the bronze age?

The bronze age that period, during which humans used weapons and implements made of bronze. It first began in the far east and maybe dated 5000-1200 BC in the middle east and about 2000-500 BC in Europe. The first part of the bronze age is also called ‘CALCOLITHIC’ or copper age since the translation from the stone age to the bronze age. A human could smelt copper but did not yet manufacture bronze. At around 2000 BC, tin was added to copper, to make bronze.
What is the iron Age?

The iron age is the period around 1200- 550 BC that followed by the bronze Age. When humans made weapons, tools, and farming implements of iron or steel. In Europe, it began around the eighth century BC and in the middle east, around the eleventh century BC. The first systematic production of iron began in Anatolia in what is modern-day turkey. Agricultural practices religious beliefs and artistic styles also developed during the iron age.

When where the first hominid fossils discovered and where?

The first hominid fossils to draw major attention were discovered in the1920’s in Africa. A specimen founded in 1924 was called the TAUNG child. It was an australopithecine infant skull discovered in a cave deposit at TAUNG, South Africa. Although the brain was small (410 cm­­3), its shape was rounded, unlike that of chimpanzees and gorillas, and more like a modern human brain.

 

What are the major changes by which human evolution is characterized?

Human evolution is characterized by a number of morphological, developmental, physiological, and behavioral changes that have taken place since the split between the last common ancestor of humans and chimpanzees. The most significant of these adaptions are; bipedalism, increased brain size, lengthened ontogeny (gestation and infancy) and decreased sexual dimorphism. Other significant morphological changes include the evolution of a power and precision grip, a change that first occurred in Homo erectus.

Muscles

What are the muscles? muscles are soft tissues, which can be described as the 'engine' that our body used to people itself. Like any other engine, muscles turn energy into motion. They are long-lasting, self-healing and able to grow stronger with practice. A normal human body has more than 600 muscles. They account for about half of a person's weight. What do muscles do? Muscles do everything from allowing us to walk to keep our blood flowing. It would be impossible for us to do anything without our muscles. Muscles have the ability to contract and expand, and so they can maintain the position of the body parts, as well as facilitate the movement of internal organs. What are the muscles made up of? Muscles are made up of fibres, a type of elastic tissue. Each fibre is made up of long thin cells which are packed in bundles. Each bundle is wrapped in a thin skin called the perimysium. The bigger the muscle, the more bundles of fibres it has. Inside the muscles, there are nerv...

Habitat

Where did the first human beings live? There is evidence that the first human beings lived in the forest and caves along the southern coast of Africa, most likely around six or seven years ago. Though the first human walked upright on the ground, they spent much of their time in trees. The great apes lived (and still live) in tropical rainforests. It is thought that human evolution began when a group of apes began to live more frequently un the savanna, which was more open, with trees, shrubs, and grass. This group, the australopithecines, started walking on two legs since they began to use their hands to carry objects. What did the earliest humans live on? The earliest humans probably lived primarily by scavenging, not actual hunting. Rather than killing large animals themselves for meat, they use carcasses of large animals killed by other predators or carcasses from animals that died at natural causes. They also fed on leaves and fruits. Those living on the coast probably used ...
