The First Life Forms on Earth - Eoarchean Earth - 3.8 billion years ago, 770 million years after the formation of the Earth, the first life forms appeared as a unicellular organism. Bacteries and archeobacteries (archaea) began to populate the Earth's surface while the atmosphere was still filled with volcanic gases and probably without oxygen. In this illustration, these micro-organisms came out of the ocean to attach themselves to the rock remains of a caldera, bringing colour to this monochrome landscape. 770 million years after the formation of the Earth - - 3.8 billion years ago - - the first life may have appeared in the form of simple, single - celled organisms. Bacteria and archaea may have even found a way to populate the otherwise sterile and inhospitable surface. The atmosphere would likely have consisted solely of gases vented by volcanoes: carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen, methane, hydrogen, methane, ammonia, and water vapor.

Devonian Canopee - Artist's View - Devonian Canopy - Artist's View of an Archaeopteris Forest about 380 million years ago. The fossil record reveals that great forests of Archaeopteris covered much of the Earth 380 million years ago. The large umbrella - like fronds appear to have been optimized for gathering sunlight at the canopy level while still permitting enough light to reach the shorter and younger trees. It was great forests like these that helped to draw much of the carbon dioxide out of the primeval air while releasing the oxygen we breathe today

First plants on Earth - Artist view - First plants - Artist view - Artist view - Artist view of the first plants (Cooksonia caledonica) that appeared on Earth in Silurian more than 400 million years ago. Species of Cooksonia caledonica, the only witness to a spectacular Late Silurian sunset, establish a tenuous foothold on a mound of ancient lava. 600 million years ago the Earth's oceans were teaming with life, however it wasn't until 200 million years later that the first plants emerged from the waters and made the Earth's surface their home. They were simple plants, standing only a few inches tall, consisting of slender stalks with branches and rounded structures called sporangia. The sporangia, common to funguses and non - seed plants, produced and contained the spores required for reproduction

The disappearance of dinosaurs - Artist view - Tylosaur and KT Event - Artist view - Impact of the asteroid responsible for the disappearance of dinosaurs about 65 million years ago. In the foreground, a tylosaurus, a large carnivorous marine lezard. The very end of the Mesozoic is marked by evidence of a devastating asteroid impact 65 million years ago, which is termed the KT event, referring to the Cretaceous (K) -Tertiary (T) transition. This impact likely contributed to the demise of the dinosaurs, although recent findings call into question how decisive the blow actually was. In this image, a huge tylosaur, a relative of today's varanid lizards such as the Komodo dragon, faces its last few minutes of existence in a Texas lagoon. Over the horizon looms the rising ejecta from the KT impact, which occurred in what is today the Yucatan

Arthropleura - An arthropleura crawls among ferns in a carboniferous forest 310 million years ago. The Arthropleura is considered to be the largest arthropod of all times measuring 2-3 metres in length. He is a distant relative of arthropods such as a thousand-legged. A four foot long Arthropleura crawls amidst seed ferns from the genus Neuropteris in a Carboniferous forest 310 million years ago in what is today Scotland. Growing up to 8 feet long and 18 inches wide, Arthropleura was the largest known terrestrial arthropod of all time. A combination of a higher percentage of atmospheric oxygen and relatively few terrestrial predators may have enabled Arthropleura to evolve to such an enormous size. Despite its fierce appearance, Arthropleura is currently believed to have been a vegetarian. In the shadows on the upper right are “” roachoids,””” primitive ancestors of modern cockroaches

Arthropleura - An arthropleura crawls among ferns in a carboniferous forest 310 million years ago. The Arthropleura is considered to be the largest arthropod of all times measuring 2-3 metres in length. He is a distant relative of arthropods such as a thousand-legged. A four foot long Arthropleura crawls amidst seed ferns from the genus Neuropteris in a Carboniferous forest 310 million years ago in what is today Scotland.

About a million years later the Sun began shining when it accrued enough mass to ignite its hydrogen fusion furnace. The ensuing solar wind purged the infant solar system of much of its nebular origins, while leaving dust and debris, including asteroids and planetoids, in the plane of the ecliptic to be swept up by the forming planets.

These dust accreted to form our planet; it was subjected to a large bombardment of meteorites. A molten, infant Earth is impacted by an object about 10 miles in diameter, releasing 200 million times a much energy as the largest manmade explosion. While this collision appears negligible when compared to the scars of much larger encounters, a similar impact four billion years later may have resulted in the extinction of the dinosaurs. The Earth accrued the majority of its mass during the 100 million years following the formation of the Sun, a period referred to as the cosmic bombardment.

The Moon and all the inner planets of the Solar System show evidence of a long and violent history of encounters with meteorites and asteroids - leftover debris from the formation of the Solar System. This image depicts an asteroid colliding with the Moon about 95 million years ago. The perspective is from the surface of the Earth in what today is Egypt. The impact would have released millions of times more energy than today's largest nuclear weapon, creating a flash of light that would be far brighter than any star in the sky.

Carboniferous fauna and flora - Calamites & Meganeura - Meganeura, giant dragonflies whose wingspan could exceed 80 cm, fly among calamites and asterophyllites. Giant Meganeura, resembling and related to present - day dragonflies, flutter between Calamites and Asterophyllites in a Carboniferous scene from over 300 million years ago. Now extinct, Calamites and Asterophyllites are related to today's horsetails, though they grew much larger. The Calamites resembled modern “” Christmas tree”” conifers, while the Asterophyllites looked somewhat like modern Thuja (arborvitae)

This is how the Earth may have appeared 600 million years ago following the Cryogenian “” Snowball Earth”” period. The worldwide glaciers have melted and the ocean is largely liquid again. During this, the Ediacaran period, it is hypothesized that all of the Earth's landmasses had merged into a single supercontinent known as Pannotia, also known as the Vendian supercontinent. Surrounding this massive landmass is the vast Panthalassic Ocean, also known as Panthalassa. While the ocean was home to a variety of evolving multicellular life forms including the ubiquitous Dickinsonia costata, it is not believed that life had moved to dry land with possible exception of bacteria and other microbial colonies

Flanking the Ichthyostega are Rhacophyton ceratangium, ancient shrubs that are thought to be one of the earliest ferns. The reddish fruit - like nodules attached to the fronds on the right are sporangia, enclosures in which spores are formed. The large tree - like trunk on the far left is the base of a young Archaeopteris. In the foreground are prehistoric arthropods - - a millipede on the left and on the right cockroaches on trunk of a decaying Lycopsid. Arthropods had been walking the Earth for 40 million years before vertebrates like Ichthyostega began venturing ash

Ichthyostega - View of an Ichthyostega 365 million years ago at the upper Devonian. Half-fish, half-terrestrial animal, the Ichthyostega was about 1 metre long.

Carboniferous fire - Carboniferous firestorm - Fire in a forest of ferns, sigillaria (sigillaria), calamites, cordaites and asterophyllites. In the foreground giant invertebrae try to take refuge in water. Fire rages through a prehistoric forest of towering Sigillaria and Cordaites, Asterophyllites, Calamites, and ferns. In the foreground a potpourri of giant Carboniferous invertebrates flee the conflagration, heading for the only real estate not subject to burning: water. On the left is a giant, 3 foot centipede; in the center is a giant Arthropleura, the largest known arthropod ever to walk the earth; on the right is a two - foot - long scorpion, and in between are dozens of prehistoric “” roachoids,””” some taking briefly to the searing air. On the far left submerged in the relative comfort of the water is a Dendrerpeton awaiting the prospect of an easy meal. 300 million years ago the Earth's atmosphere may have held considerably more oxygen than today; the air may have been as much

Landscape of the Devonian - Calamites & Asteroxylon - Landscape of the early Devonian, about 390 million years ago, with calamites and asteroxylon (in the foreground). This is how a forest of Calamites and Asteroxylon may have appeared just about anywhere on the Earth 390 million years ago. The Calamites are the slender “” Christmas tree””” shaped plants. They grew as tall as many of today's conifers, though they are the ancient ancestors of the much smaller modern horsetails. The snake - like curlicue plants in the foreground are the now - extinct Asteroxylon, which emerged at the beginning of the Devonian period about 417 million years ago

India 70 million years ago - Artist's view - Late Cretaceous India - India seen in the upper cretace about 70 million years ago. The north is upstairs. To the west, Madagascar separates from India. This is how the Indian subcontinent may have appeared 70 million years ago during the Late Cretaceous period. Looking north, immediately to India's west is the island continent of Madagascar and further west is the eastern coast of southern Africa. In the distant past India and Madagascar formed a single continent, however India was part of a separate tectonic plate that subsequently began to drift northward. This northward motion (covering about 8 inches per year making it among the fastest on the Earth's lithosphere) split India from Madagascar and carried it north across the Tethys Ocean until it collided with Eurasia about 50 to 35 million years ago. This collision between the Indian and Eurasian plates joined India to South Asia and created the Tibetan Plateau and the Himalaya Mountains

Anomalocaris - Anomalocaris was a prehistoric invertebrate forming part of the arthropods or more precisely the anomalocarid arthropods, Anomalocaris would be the Earth's first superpredator. He would have lived between 535 and 520 million years, at the beginning of the Cambrian. It was carnivorous and was up to one metre long. The image also shows a trilobite (Oleonides serratus), sponges (Vauxia and Wapkia), Dinomischus (flower-shaped animal) and a meduse. An anomalocaridid from the genus Anomalocaris cruises a Middle Cambrian ocean floor about 500 million years ago. Growing to over three feet long, Anomalocaris is believed to have been a predator whose diet included trilobites and may have been one of the earliest arthropods. This image includes a trilobite from the species Olenoides serratus and sponges from the genus Vauxia and Wapkia. The small, flower - like animals (yes, like the sponges they are rooted animals) are from the genus Dinomischus. Above and behind the Anomalocaris

Archean stromatolites - Illustration showing the shores of an ancient sea 3 billion years ago. In the foreground, stromatolites, aggregation of sediments and cyanobacteries. Stromatoliths have undoubtedly contributed to our dioxygen-rich atmosphere and the ozone layer that allowed the development of a more complex terrestrial and oceanic life. Dome - shaped stromatolites, averaging three feet high and four feet wide, populate the shallow shore of an ancient sea 3 billion years ago. The Moon looms near the horizon, much closer to the Earth than it is now and therefore appearing considerably larger, but otherwise looking much like the moon we know today. 3 billion years ago the first macro evidence of life on Earth may have appeared in the form of large aggregations of microorganisms and associated sediments known as stromatolites. Cyanobacteria (AKA blue - green algae) were likely one of the primary contributors to these aggregations. During the Archean Eon the Earth's atmosphere contai
