First of all, the Cambrian Explosion is designated as a huge diversification event taking place between 543 to 506 MYA, when most of the phyla extant (living) today appeared. So the first chordates, shelled organisms and arthropods were seen in the Cambrian period. Therefore, complex bilateria dominated the Cambrian scene.

What important event in the animal evolution marks the beginning of the Cambrian?
Referred to as the "Cambrian explosion", most major animal groups first appeared in the fossil record beginning about 530 million years ago.
The Cambrian explosion resulted in the evolution of the first?
complex multicellular organisms with hard parts, such as shells and skeletons. This period saw the emergence of diverse marine life forms, including arthropods, mollusks, and chordates, laying the foundation for future evolutionary developments.
What happened in the Cambrian explosion?
The Cambrian explosion is supposedly a time in Earth's history about 570 million years ago when life evolved extremely quickly from single-celled organisms to complex plants and animals.There is a major problem with this theory, in that it is a cataclysmic event. Evolutionary theory avoids catastrophic explanations whenever possible (and only accepts them when they could be considered common), but this Cambrian explosion happening over a period of a couple million years is almost instantaneous compared to the 4.6 billion-year Darwinian model of evolution.Picture, if you will, the history of the Earth in a 24-hour day: the first few hours show no signs of life; but at about the fifth hour, you start to see single-celled organisms floating around; this life stays like that for sixteen hours until the twenty-first hour, when all of a sudden, you see complex and diverse life come into being in a span of less than two minutes.http://www.youtube.com/watch?v=TUC9drrEAVU&feature=relatedThis theory is only a feeble attempt to explain how there seems to be no fossil evidence of the creatures between single cells and complex vertebrates and plant life; in fact, this explanation is even more miraculous than the Creation account, because where Creation states that an Intelligent Designer made everything from nothing, evolution claims that chance played the leading role in causing everything to grow from nothing to everything.If you'll notice, the cause and effect of both Creation and Evolution are the same (everything from nothing), but the difference is chance and intelligence. There are two possibilities: either we are a product of random chance and quantum fluctuations billions of years ago, and thus have no purpose; or we are a product of supreme intelligence, and should find our purpose through seeking this intelligence and doing His will (Psalm 27:4).
After the Cambrian explosion what form of life evolved?
Single celled organisms.
What is meant by term Cambrian explosion?
The Cambrian explosion is an apparently sudden increase in fossils marking the separation between Precambrian rocks and Cambrian rocks. At one time this was believed to mark the beginning of multicellular life, but in fact it only marks the evolution of hard body parts (most of which were made of calcium carbonate). It turns out that there were as many multicellular organisms in the late Precambrian as there were during the Cambrian explosion at the beginning of the Cambrian, but the lack of hard body parts in those organisms made the formation of easy to identify fossils of those organisms much rarer.
Why did the Cambrian explosion may not have been an explosion?
The Cambrian Explosion wasn't a literal explosion. Instead, it was a span of time when organisms evolved into an immense number of new forms, and biodiversity increased greatly, reaching its modern level. The Cambrian Explosion occurred between 530 and 450 million years ago.
What era did the Ediacaran Fauna Live?
The Ediacarian fauna are from the Cambrian Explosion. The Cambrian Explosion occurred in the Cambrian period. The Cambrian period was part of the Paleozoic era.
Why is the Cambrian Period called the Cambrian Explosion?
The Cambrian Period is called the Cambrian Explosion because it is characterized by a sudden increase in the diversity of multicellular life forms, including the appearance of many major groups of organisms. This period saw the rapid evolution and proliferation of complex marine life forms, marking a significant point in the history of life on Earth.
Explosion of life what period?
Cambrian.
Where can you see the evidence of the Cambrian explosion in the world?
Any time you see an animal. The Cambrian explosion was when the different kinds of animals developed - all the different animal phylums. So if you see an insect on a mammal you see the Cambrian explosion.
Many new groups of organisms evolved in a relatively short time in an event called the . Great Ice Age Cambrian Explosion Chicxulub Collision Milankovitch Cycle?
Cambrian Explosion. This was a period about 541 million years ago when a diverse array of complex multicellular organisms appeared in the fossil record, marking a significant increase in biodiversity.
How long ago did the Cambrian explosion happen?
The Cambrian explosion occurred about 541 million years ago. It marked a period of rapid diversification of life forms, with the sudden appearance of a wide variety of complex multicellular organisms in the fossil record.
What happened during an event called Cambrian Explosion?
The sudden increase in invertebrate fossil diversity
What important evolutionary step did the Cambrian period bring to organisms?
The Cambrian period marked the diversification of multicellular life forms, leading to the development of many major animal groups known today. This period is often referred to as the "Cambrian explosion" due to the rapid evolution of diverse body plans and the emergence of complex organisms with hard parts.
What is the cambrain explosion?
