The Precambrian - From Hell on Earth to the First Animals - The History of Earth

The Precambrian - The History of Earth.

The first animals evolved during the Precambrian, these Precambrian animals, mainly the Edicaran animals, that make up the Ediacaran Biota, are the first animals ever - from sponges and comb jellies to jellyfish, Charnia, Dickinsonia, and spriggina, these are incredibly interesting extinct animals.

The Precambrian is divided into 3 eons, the Hadean, early earth, when the planet looked like hell, the Archean, where the evolution of life sped up while oxygenating the atmosphere, and the Proterozoic, when snowball earth occurred and life diversified, starting the evolution of the first animals, and plants.

This new series on SenDrev Science, The History of Earth, dives into the geologic history of the Earth, from the evolution of life, mainly the evolution of animals and their phylogeny, to geographic changes of the continents and climate change, all while explaining important parts of science - mainly pertaining to biology and geology.

The next episode will focus on the Cambrian period, and we'll examine the radiation of animal life during the Cambrian explosion.
