Evolution: Biogenesis and Development in the Precambrian

Beginning of Rock and Land

3 BCE

The Archean era began with the formation of rocks and plates across Earth from the ongoing crashing of rocks and objects on the globe.

Formation of Earth's Layers

2 BCE

With the colliding of rocks and chemicals forming, layers of the Earth started to form with mostly rock on the crust and the mantle's composed of iron and other metals.

Tectonic Plate Formation

2 BCE

With the combination of many chemicals and physical formations across the globe, many of them did not mend together resulting in the denser properties falling beneath or subducting underneath the less dense properties. This formed many of the current land structures today, or continents.

Living Formations

2 BCE

Life began to thrive from chemical compounds, carbon, and microbial mats.

Breaking Up Of Supercontinent

2 BCE

The supercontinent of Vaalbara, formed by the collection of then rock, separated due to tectonic activity from volcanoes

Kenorland

2 BCE

Many other land masses began to form, such as Kenorland, forming the base of many modern day continents and countries across the globe.

Ocean Formation

2 BCE

Oceans were formed due to the condensation of water in the atmosphere from the gas of volcanic activity. Oceans during this time also had a green hue to them due to ferrous hydroxy salts.

Formation of Organisms

2 BCE

Formation of tiny, single celled organisms that did not require oxygen.

Photosynthesis Emergence

2 BCE

Many plants began to use the modern form of photosynthesis to began growing. The sun became a vital part of life due the late Archean.

Banded Iron Formation

2 BCE

Formation of sedimentary rock from iron, chert, and cyanobacteria known to have been created in the ocean during photosynthesis.
