Geology
Based on the geology, the earth until now divided into four ages. Ages is pembabakan prehistoric periodization or consisting of:
Arkeozoicum
This era lasted about 2500 million years old, at that time the earth's crust is still hot, so there is no life Paleozoicum
Paleozoicum or often referred to as the primary age or older living era lasted 340 million years. Living creatures that emerged during this era such as micro-organisms, fish, amphibians, reptiles and invertebrate animals that do not.
Mesozoikum
Or Mesozoic age are often referred to as secondary or middle age of life went on for about 140 million years, between 251 to 65 million years ago. In medieval times, the reptiles evolved and spread throughout the world so that at this age are often referred to as the age of reptiles.
Neozoicum
Neozoikum or mid-life period is divided into two ages, ie age and age Kuartier Tertiary. Tertiary Period lasted for about 60 million years. This era is characterized by the development of the mammals.
Meanwhile, the Age Kuartier marked by the emergence of humans so it is a most important era. Age is then subdivided into two ages, ie age and Holosin Pleitosen. Age Pleitosen (Dilluvium) lasted approximately 600,000 years are characterized by the existence of early humans.
Pleistocene era is characterized by expansion of ice sheets at both poles of the Earth (glacial period) and interrupted with the times when the ice melts again (interglacial era). This situation is alternated during the time of pleistosin to four times. In the tropics this glacial period of rainy days (pluvial age) who interrupted with a dry period (interpluvial).
At the time of glacial sea level has dropped dramatically so that only complains of the dry seabed into land. In Indonesia, the western part of the dried seabed is called the Plain of Sunda, whereas in the eastern part of Indonesia called the Plain of Sahul. Sunda plateau has led to the western islands of Indonesia to become one with the continent of Asia, while the Plain of Sahul has also connects the islands of eastern Indonesia to the Australian continent. That is why the fauna and flora of western Indonesia is similar to the fauna and flora of Asia and vice versa fauna and flora of eastern Indonesia are similar to Australia. Humans who live pleistosin age is homo erectus species, which is a supporter of the old stone culture (Palaeolithicum).
Pleistosin era ended about 10,000 years BC, followed by the coming of age or age Holosin Alluvium is still going on until now. From this era came the ancestors of today's people, namely the species homo sapiens or intelligent beings
