The Cambrian Explosion is a sudden appearance of all life as we know it. There are exceedingly few that come before this and those that follow the Cambrian show no differences than their ancestral cousins or predecessors that follow. It is like an explosion of life that appears almost instantaneously on earth.

Certains auteurs n'hésitent pas à parler de « big bang zoologique au Cambrien », avec l'apparition en quelques dizaines de millions d'années de la quasi-totalité The Cambrian explosion From about 570 to 530 million years ago, an evolutionary burst of life forms occurred, often referred to as the "Cambrian Explosion." This marks an important point in the history of life on earth, as most of the major lineages of animals got their starts during the Cambrian Period and have been evolving ever since. 2021-04-10 · The Cambrian Explosion continues to explode: “Evidence is converging,” paleontologists have written recently, “towards picturing the Cambrian explosion as even swifter than what we thought.” This does not look like a disappearing concept at all. Some scholars should leave sleights of hand alone. 2013-10-15 · Last week we looked at some of the reasons why creationists can’t stop talking about the Cambrian explosion. Today let’s look at a new paper published in Science 1 that explores possible causes of the Cambrian explosion, the seminal diversification of animal life that began about 530 million years ago. Se hela listan på livescience.com In the Cambrian Explosion, numerous forms of highly complex animal life appeared suddenly in the rock record with absolutely no evolutionary precursors. At the time Darwin’s Origin was published in the 1800s, the lowest-most fossiliferous rock layer where complex life first appears—what we now call the Cambrian—was then known as the Silurian.

During this event, the “Cambrian explosion,” many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock.

The rapid diversification of multicellular animal life that took place around the beginning of the Cambrian Period. It resulted in the appearance of almost all modern animal phyla.

Paleontologist Dr. Kurt Wise suggests that as you look at the museum mural of the “Cambrian Explosion,” you should think of it as a picture of life before the Flood. He points out that the animals found in this layer are complex, completely formed, and are part of fully integrated ecosystems of marvelous beauty and wonder, reflective of the nature of the Creator.

Trilobites first appeared in the Early Cambrian (during what is called the Cambrian Explosion); they increased in diversity in the Devonian period; and their numbers decreased in the Silurian (probably due to the appearance of sharks and other predators).
