What important adaptation help protect organisms of the early Cambrian period?
hard body parts
What important event in animal evolution marks the begging of the Cambrian period?
The Cambrian period, which began around 541 million years ago, is marked by the "Cambrian Explosion," a significant event in animal evolution characterized by a rapid diversification of life forms. During this time, many major groups of animals first appeared in the fossil record, including early ancestors of modern phyla. This event highlights the development of complex organisms with hard parts, allowing for better preservation and increased ecological complexity. The Cambrian Explosion fundamentally transformed marine ecosystems and set the stage for future evolutionary developments.
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.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
What is the division of the Cambrian and Pre-Cambrian periods?
The Cambrian period occurred approximately 541 million years ago, marking the beginning of the Paleozoic Era. The Pre-Cambrian is a broad division of time before the Cambrian period, encompassing about 4 billion years of Earth's history, including the formation of the planet and the evolution of life prior to complex multicellular organisms.
What important adaptation help protect organisms of the early Cambrian period?
hard body parts
Why is it important to scientists that many organisms during the Cambrian period had hard parts?
Referred to the Cambrian explosion is the Cambrian period. Shells and exoskeletons had hard parts. The Cambrian period was the first of the Paleozoic Era.The hard parts made the preservation of their shapes, and sometimes their body cavities, much more easy to recognize as a fossil. The earlier soft bodied organisms required very fine silts for their effective preservation. A representative group they found are the Ediacaran fauna.

When in the evolutionary timeline did bilateral symmetry first emerge?
Bilateral symmetry first emerged in the evolutionary timeline during the Cambrian period, around 540 million years ago.
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.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
What is the division of the Cambrian and Pre-Cambrian periods?
The Cambrian period occurred approximately 541 million years ago, marking the beginning of the Paleozoic Era. The Pre-Cambrian is a broad division of time before the Cambrian period, encompassing about 4 billion years of Earth's history, including the formation of the planet and the evolution of life prior to complex multicellular organisms.
The appearance of the most complex and the greatest diversity of organisms occurred during what time period?
The appearance of the most complex and the greatest diversity of organisms on Earth occurred during the Cambrian Period, around 541 million years ago. This period is known as the "Cambrian Explosion" due to the rapid diversification of multicellular life forms.
What are some plants from the Cambrian period?
The only plant from the Cambrian period is algae.
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.
What organisms did the Cambrian explosion make?
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.
