species evolution epic
Procaryote is the original form of life. About 2.5 billion yeas ago, the oxygen percentage is high and this cause the Oxygen Holocaust. Then 1.6-2 billion years ago, eukaryote showed.
As Charles Darwin put it at the end of The Origin of Species, "there is a grandeur in this view of life, with several powers having been originally breathed into a few forms or into one, and that whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning, endless forms most beautiful and most wonderful have been and are being, evolved "
The keystone of our story is Evolution by Natural Selection. And similarly, the conception of Survival of the Fittest came up later. Since the start of multi-cellular life, there has been 5 mass extinction. Species' competing in niches, or some climate or astronomy impact both can be the culprit of extinction. Then new trait adapt again, which called Adaptation Radiation.
Ediacaran Era (630-542 million years ago)
Give us the first extensive fossil evident of multi-cellular organism.
Cambrian Era (542-482 million years ago)
The most famous specie start in this era is Trilobita. They didn't go extinct until 300 million years ago. (1000 times of human)
Ordovician Era (485-445 million years ago)
Photo synthesis made their first tentative steps out of the sea, into a new niche, the land.
This era went through first a major freezing period, killing off many warm-water species. Then went through a radical heating period, killing off many cold-water species.
Silurian Era (445-420 million years ago)
Devonian Era (420-360 million years ago)
Forests came into being. And plants with woody covering allowed themselves to be taller.
And, our vertebrate ancestor had survived on land. From these amphibian ancestor, stated to evolve to species with 4 lumbers and 5 digits.
Carboniferous Era (360-300 million years ago)
Reptile.
Permian Era (300-250 million years ago)
Forests are dried out into desert. Mammals evolved.
There is a extinction caused by volcanoes in Siberia.
Triassic Era (250-200 million years ago)
Dinosaurs reigned the world. They whopped the world for 135 million years.
Jurassic (200-145 million years ago)
Dinosaurs.
Cretaceous (45-66 million years ago)
Dinosaurs.
Then we will explore the nascent beginning of a new phase of complexity, the human.
The slow waltz of plates tectonics continue to pull Eurasia and Americas apart, expanding the Atlantic Ocean. Primates colonized Americas separated by the vast ocean.
45 million years ago, Australia split from Antarctic.
40 million years ago, India smashed into the Eurasia continent with such force that it created the world's tallest mountain range.
25-30 million years ago, the line of the apes diverged from the old-world monkeys. Homo sapiens have been around for 250,000 years. We have been expanding our toolkits from stone tools, to spearfishing, to trade and to mining. And by 40,000 million years ago, we has art including carve images, decorative beads and other form of jewelry.
