There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the “molecular clocks” in the DNA of living ...
TheCambrian explosion was the largest diversification of lifein Earth’s history. Everything before this era was Precambrian. We couldn’t identify life because we didn’t havefossilized shells or animals. This is when hard-shelled invertebrates originated in the oceans. The Cambrian explosion starte...

The Cambrian Explosion began 541 million years ago and lasted roughly 13 to 24 million years. During this period, most major animal phyla originated. 0.6 billion years ago 500 million years ago The first land plant is hypothesized to have formed 470 million years ago. These plants were non-va...
By 2010 the digital nomad era had begun in earnest. Digging through the historical archives, 2010 is like a Cambrian explosion event in the digital fossil record. More digital nomad-themed sites started appearing, and people are identifying as digital nomads. ...
The first hard parts on animals appear during the Cambrian Period 545 million years ago. While researchers have yet to agree on the reason for this explosion of life, many think a combination of factors spurred this extraordinary jump from single cells to complex creatures. For instance, the ...
Cambrian explosion Many modern animal phyla suddenly appear Most of life is still in the seas, but some plants and invertebrates are found on land shortly First fossil chordates and vertebrates Provides the first evidence ofpredator-prey interactions ...
Cambrian Explosion 530 million years ago Colonization of land 500 million years ago Tetrapods Appear 360 million years ago Formation of the supercontinent Pangaea 250 million years ago Fifth mass extinction that gave way to adaptive radiation of mammals ...
This transition is referred to as the Cambrian explosion. How did the Precambrian era start? The Precambrian era started with the formation of the solar system, planets, moons, and other constituents. The Precambrian era lasted 4,000 million years. What lived in the Precambrian era? Primitive ...
