What the beginning of the Paleozoic era marks?
The start of the Paleozoic Era was marked by a huge diversification of life known as the Cambrian Explosion. Many genre of life emerged during the Cambrian Period. Although plants and animals were around in the Pre-Cambrian it was not until after the extinction event that immediately proceeded the Paleozoic that many advanced forms of life evolved such as multi-celled plants and advanced animals such as the arthropods.
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.
Where did all the Cambrian animals live?
During the Cambrian period, animals primarily lived in the ocean. They inhabited various marine environments such as shallow seas, reef systems, and coastal regions. Some also lived in deeper waters, but the majority of Cambrian animals were marine organisms.
Animals in the preCambrian period?
The group of animalia (animals) did not fully form until the Cambrian period. There is evidence of simple life (single-celled) and small multi-celled life forms from before the Cambrian explosion.
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.
What animals went extinct during Cambrian Period?
There is limited evidence of animal extinctions during the Cambrian Period, but some organisms failed to evolve and adapt to changing environmental conditions. It is believed that certain early Cambrian species became extinct due to factors such as competition, predation, and environmental shifts. Examples include trilobites and some primitive arthropods that did not survive past the Cambrian Period.
How many conenents did the Cambrian have?
4
The Cambrian period is also called the?
The Cambrian period is also called the "Cambrian explosion" due to the sudden appearance and diversification of many major animal groups.
What is the nature of rock during Pre Cambrian Era?
AnswerThe same three rock types existed in the Pre-Cambrian as exist today: sedimentary, igneous, and metamorphic. The main difference was that in the Pre Cambrian there were no large animals. As a result, there were no coral reef to make limestones. The Pre Cambrian is a very long period of time though (4 billion years). There are some major differences between early and late pre Cambrian rock.
What animals lived in the Cambrian period?
"one celled organisms" Edit: No; by the Cambrian, life on earth had progressed to include many multi-cellular organisms such as echinoderms, trilobites, sponges and small molluscs.
What is the difference between the Cambrian and preCambrian periods?
The difference between The differeence between the Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of thee evolved predators. The difference between Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved predators.rian fossils Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved predators.
What is unique about the Cambrian Sea?
Currently I am studying that. What I have found is that hunting started. Other animals began eating other animals. I'll post more about this subject soon!
