Logarithmic timeline

This logarithmic timeline, based on logarithmic scale, is able to show all history on one page in ten lines. In this chart, each row is defined in years ago, that is, years before the present date, with the most recent at the top of the chart.

  • A period corresponds to an epoch
  • An event is an occurrence of an observed or inferred process
    • Progress refers to civilizational advances, such as inventions and scientific discoveries; see Timeline of invention for more.
    • Regression indicates a problem or crisis that can be considered as the opposite of progress: having a retardative effect on life or civilization.
      • This is an arbitrary listing as progress toward the current state of human civilization is the apparent selection criterion.

Another interesting property is the ordering of experience into intuitive notions of experience (this is not the case for us with linear scales, for example the years 3, 432, 623, 096 BC and 3, 432, 623, 097 BC).

Early Pleistocene epoch of Quaternary period: The bloom of homo erectus, development of language, mastery of fire and Acheulean stone technology that serves as weapon for hunting and protection against any existing species. Early forms of division of labor (i.e. for hunting). Artificial dwellings of boughs and furs are inhabited and the environment comes under the influence of social control.

Early stone age: In the Pliocene epoch, the first human-like ancestors live. The oldest is Australopithecus, followed by homo habilis and the early homo erectus. The most ancient stone age technology, Oldowan, emerges. The brain volume grows to an amount comparable to that of modern mankind. This strong increase in encephalization is regarded as mystery; one attempt of explanation is a begin of meme processing.

Era of apes: In the Oligocene epoch, Aegyptopithecus appears. Apes have 3D sight and skillful hands with opposable thumbs for living in the evolution-generated 3D environment of forests. They (like other mammals) are said to be capable of Metacognition , the ability of doubt and autobiographic memory.
In the Miocene epoch, a descendant was Dryopithecus , ancestor of all modern apes and mankind.

Era of mammals: In the Cretaceous period of Mesozoic age, birds and placental mammals exist in the shadow of the dinosaurs. These endotherms (and maybe some highly developed dinosaurs) share a special capability for emotion and social behaviour.
After the extinction of dinosaurs in the Paleogene subperiod of the Tertiary period, endotherms gain domination of the land; primates appear.

Era of animals: After the Varanger glaciation in the Ediacaran period of the Neoproterozoic age, the first multicellular fungi, plants and animals emerge.
The Paleozoic age begins with the Cambrian explosion spreading a great variety of animal forms; Nervous systems appear with senses, brain and behavior. In Silurian and Devonian time, life enters the land.
The Mesozoic age brings the Dinosaurs.

Era of single cells; The Archaean age ends with the accumulation of Oxygen by Cyanobacteria, the Proterozoic begins:
In the Paleoproterozoic our biosphere stabilizes with aerophile bacteria, in the Mesoproterozoic age emerge cells with nuclei capable of sexual reproduction and the Neoproterozoic (until the Varanger glaciation from 750 - 580 M years ago) prepared multicellular life.

Milky Way: The Panspermia hypothesis suggests life to emerge in the depths of space long before. Arisen from Universe soon after Big Bang, a first generation of stars provides heavy elements for Chemistry & planets after some B years.
Earth: Hadean & Archaean age; life in form of archaea appears in a comparatively small fraction (600 or less to 950 M years) of the period of single cells.
Drake equation factors: R* (star formation), fp (planets), ne (planetary potential to bear life), and fl (actual development of life).
