Most likely is the postulation that larger plankton developed, whose corpses and droppings were large enough to actually make it to the sea floor. This opened up the mid-ocean and ocean bottom to new life forms that could take advantage of the new nutrient sources.

What does the term Cambrian Explosion mean?

The sudden appearance of most of the major animal phyla within the fossils early in the Cambrian period. This caused a sudden diversification of life.


What may have caused the explosion of life during the Cambrian period?

The explosion of life during the Cambrian period, known as the Cambrian Explosion, is believed to have been driven by several factors. Increased oxygen levels may have allowed for more complex multicellular organisms to thrive, while the development of predation could have spurred rapid evolutionary adaptations. Additionally, the emergence of new ecological niches and the genetic innovations such as the development of hard shells and exoskeletons contributed to this diversification. Together, these factors created an environment conducive to unprecedented biological diversity.


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.

How did earth's organisms change during the first period of Paleozoic era?

During the first period of the Paleozoic era, the Cambrian period, there was an explosion of biodiversity known as the Cambrian Explosion. Many new types of organisms evolved, including the first trilobites, mollusks, and brachiopods. This period marked the appearance of complex multicellular life forms and the development of hard parts like shells and exoskeletons.


According to the fossil record how many years ago did life first seem to appear on Earth?

The Cambrian Explosion, a period between about 540 and 530 million years ago when many major animal groups appeared in the fossil record. This is when animals first developed hard shells and skeletons, so they became much more easily fossilised. Nobody is quite sure what caused the Cambrian Explosion, but increased oxygen levels in the air after the melting of a huge ice age around 600 million years ago may have led to an increase in the size of animals in the oceans; in turn they developed skeletons and shells to support their larger bodies. The evolution of predators may have inspired prey animals to develop shells, as well. We do have fossils before the Cambrian Explosion, but these are simple, soft-bodied, small and rare, so the origins of animals are still shrouded in mystery.

When gas and fire come together what makes the explosion?

An explosion is caused by fuel burning very rapidly. The products of combustion expand rapidly and with extreme force, and the result is what we call an explosion. So...if you put gasoline on a fire and it explodes, as it will, the explosion was caused by the fire.
