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...
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 ...

the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago – nearly 60 million years before skeletal animals appeared during a huge growth spurt of new life on Earth known as the Cambrian Explosion. ...
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 ...
The first life forms appeared, and the evolution of these life forms started at the end of the Precambrian era. 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, ...
