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 important adaptation help protect organisms of the early Cambrian period?
hard body parts
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 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.

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 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.
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.
Was life not very diverse during the Cambrian period?
The Cambrian period was marked by a rapid diversification of life known as the Cambrian explosion, where many new body plans and major animal groups appeared. This period saw the emergence of various marine organisms with complex body structures, leading to a significant increase in biological diversity.
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.
