How Earth Has Evolved Over 750 Million Years?
See How Earth Has Evolved Over 750 Million Years?
Earth formed around 4.54 billion years back. While there are several hypotheses that claim to clarify its development, it is safe to, at any rate, say that our globe used to look not at all like what it does today. Truth be told, you can go to “Dinosaur Pictures and Facts” to know what our globe looked like around 750 million years ago. Trust us this site is a delight on the off chance that you are into natural and ecological history and the evolution and development of our planet.

The site has a devoted webpage that demonstrates an interactive globe of old Earth. At the best, the site gives you a chance to choose an alternative that reaches from 0 to 750 million. You can choose any of the times and see what our planet used to look like in those days. You can likewise utilize the arrow keys on your keyboard to move forward and backward between eras for a true look timelapse-like look at the earth. Alongside the imagery, it’ll additionally give you a depiction of that specific period in time.
750 million years ago
Cryogenian Period
Glaciers may have covered the entire planet during the greatest ice age known on Earth. Different types of single-celled organisms such as green algae appear for the first time.
600 million years ago
Ediacaran Period
Life is evolving in the sea, and multicellular life is just beginning to emerge.
540 million years ago
Early Cambrian
A mass extinction has just taken place. Afterward, the fossil record shows a dramatic expansion of animal life in the sea, known as the “Cambrian explosion.” Animals are beginning to evolve shells and exoskeletons.
500 million years ago
Late Cambrian
The ocean is teeming with life following a dramatic expansion of animal diversity in the sea, known as the “Cambrian explosion.” The forms of some animals show ancestry to modern animals.
470 million years ago
Ordovician Period
The seas are diverse and the first coral reefs emerge. Algae is the only multicellular plant, and there is still no complex life on land. Jawless fishes, the first vertebrates, appear.
450 million years ago
Late Ordovician
The seas are diverse and the first coral reefs have emerged. Algae is the only multicellular plant, and there is still no complex life on land. Jawless fishes, the first vertebrates, appear. A mass extinction is about to take place.
430 million years ago
Silurian Period
A mass extinction took place, wiping out nearly half of marine invertebrate species. The first land plants emerge, starting at the edge of the ocean. Plants evolve vascularity, the ability to transport water and nutrients through their tissues. Ocean life becomes larger and more complex, and some creatures venture out of reefs and onto land.
400 million years ago
Devonian Period
Life on land becomes more complex as plants develop. Insects diversify and fish develop sturdy fins, which eventually evolve into limbs. The first vertebrates walk on land. Oceans and coral reefs host a diverse range of fish, sharks, sea scorpions, and cephalopods.
370 million years ago
Late Devonian
Life on land becomes more complex as plants develop. Insects diversify and fish develop sturdy fins, which eventually evolve into limbs. The first vertebrates walk on land. Oceans and coral reefs host a diverse range of fish, sharks, sea scorpions, and cephalopods. A mass extinction is about to take place that will stress marine life.
340 million years ago
Carboniferous Period
A mass extinction harmed marine life, but land organisms adapted. Plants are developing root systems that allowed them to grow larger and move inland. Environments are evolving below tree canopies. Atmospheric oxygen increases as plants spread on land. Early reptiles are evolving.
300 million years ago
Late Carboniferous
Plants developed root systems that allowed them to grow larger and move inland. Environments evolved below tree canopies. Atmospheric oxygen increased as plants spread on land. Early reptiles have evolved, and giant insects diversify.
280 million years ago
Permian Period
Landmasses merged and formed the supercontinent Pangea. Extreme conditions such as polar ice caps and deserts limited the extent of plant life, but amphibious tetrapods and reptiles diversified where plants grew. Oceans teemed with fish and invertebrate life.
260 million years ago
Late Permian
The greatest mass extinction in history is about to take place, driving 90% of species extinct. The extinction of plants reduced the food supply for large herbivorous reptiles and removed habitat for insects.
240 million years ago
Early Triassic
Oxygen levels are significantly lower due to the extinction of many land plants. Many corals went extinct, with reefs taking millions of years to re-form. Small ancestors to birds, mammals, and dinosaurs survive.
220 million years ago
Middle Triassic
The Earth is recovering from the Permian-Triassic extinction. Small dinosaurs begin to appear. Therapsids and archosaurs emerge, along with the first flying invertebrates.
200 million years ago
Late Triassic
An extinction event is about to happen, resulting in the disappearance of 76% of all terrestrial and marine life species and greatly reducing surviving populations. Some families, such as pterosaurs, crocodiles, mammals, and fish were minimally affected. The first true dinosaurs emerge.
170 million years ago
Jurassic Period
Dinosaurs thrived as the first mammals and birds evolved. Ocean life diversified and the Earth was very warm.
150 million years ago
Late Jurassic
The earliest lizards have appeared and primitive placental mammals have evolved. Dinosaurs dominate both landmasses. Large marine reptiles inhabited the ocean, and pterosaurs were the dominant flying vertebrates.
120 million years ago
Early Cretaceous
The world is warm and has no polar ice caps. Large reptiles dominate and mammals remained small. Flowering plants evolve and spread throughout the world.
105 million years ago
Cretaceous Period
Ceratopsian and pachycephalosaurid dinosaurs evolve. Modern mammal, bird, and insect groups emerge.
90 million years ago
Cretaceous Period
Ceratopsian and pachycephalosaurid dinosaurs evolve. Modern mammal, bird, and insect groups emerge.
66 million years ago
Late Cretaceous
A mass extinction occurs, leading to the extinction of dinosaurs, many marine reptiles, all flying reptiles, and many marine invertebrates and other species. Scientists believe the extinction was caused by an asteroid impact on the present-day Yucatan Peninsula in Mexico.
50 million years ago
Early Tertiary
Following the asteroid impact that killed the dinosaurs, surviving birds, mammals, and reptiles diversified. Early whales evolved from land mammals.
35 million years ago
Mid Tertiary
Mammals have evolved from small, simple forms to a diverse group. Primates, cetaceans, and other groups evolve. The Earth cools and deciduous plants become more common.
20 million years ago
Neocene Period
Mammals and birds continue to evolve into modern forms. Early hominids emerge in Africa.
