Were there herbivores during the Cambrian time period?
It is thought that most of the animals in the Cambrian Period were herbivores feeding on the Green Algae which we believe was abundant during the Period.
Was life not very diverse during the Cambrian period?
True.
During which period was Laurentia completely surrounded by passive margins?
The Cambrian
Which type of organism appeared for the first time during the Cambrian period?
Trilobites
During what time period did shallow seas cover much of the land?
The Cambrian period of the Paleozoic era ;)
What happened during an event called Cambrian Explosion?
The sudden increase in invertebrate fossil diversity
What is the cambrain explosion?
life during the early Cambrian period
Diversification of animal phyla occurred in the?
Diversification of animal phyla occurred during the Cambrian explosion around 541 million years ago. This event marked a rapid increase in the variety of body plans and structures within the animal kingdom.
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.
What is the Cambrian explosion why is it important to the history of life on earth?
During the Cambrian Explosion. life took a great step forward to a world called life. A great number of organisms were evolving all over the world.
Whatever its ultimate cause the Cambrian explosion is a prime example of?
The sudden and very dramatic increase in life forms on earth (especially in the oceans) that took place during the Cambrian period of earth's evolution. Note that in this context "sudden" means "just a few million years".
During what period did the first vertebrates appear?
The first vertebrates evolved during the Cambrian Explosion about 525 million years ago. The Cambrian Explosion, obviously, occurred during the Cambrian period. The Cambrian period was part of the Paleozoic era.
During which period in the geologic time scale was there a great increase in the variety of life forms on earth?
Cambrian perod
What is the changes that have occurred in the diversity of life on earth?
Life on Earth is less diverse now than it was during the Phanerozoic Era. The Cambrian Extinction caused a sharp decline in biodiversity.
When were fish introduced to the world?
Fish began to evolve during the Cambrian explosion around 530 million years ago. The evolution of early sharks took place in the Devonian period.
What caused the greatest increase in diversity of life during the course evolution?
sexual reproduction
All of animal phyla on Earth today evolved during what period?
All animal phyla on Earth today evolved during the Cambrian Explosion, which occurred around 541 million years ago. This period marked a rapid diversification of multicellular organisms and the emergence of most major animal groups that exist today.
