Pronunciation: [kˈambɹi͡ən ɛksplˈə͡ʊʒən] (IPA)

The Cambrian Explosion was a period of rapid diversification of life on Earth around 541 million years ago. The spelling of "Cambrian" is pronounced as /ˈkæm.bri.ən/ in phonetic transcription. The "C" at the beginning is pronounced as "k," the "a" is pronounced as "æ," the "m" is pronounced as "m," and the "b" is pronounced as "b."

CAMBRIAN EXPLOSION Meaning and Definition

1. The Cambrian Explosion refers to a significant biological event that occurred approximately 541 million years ago during the Cambrian period. It is defined as a rapid and unparalleled diversification of multicellular animal life in Earth's history. This evolutionary event resulted in the abrupt emergence of a wide array of diverse and complex animal forms, marking a turning point in the history of life on our planet.

   During the Cambrian Explosion, numerous new and sophisticated body plans and novel evolutionary adaptations arose in a relatively short period. This period witnessed the appearance of various groups of animals, including arthropods, mollusks, echinoderms, chordates, and many others that are still present today.

   This evolutionary proliferation took place in marine ecosystems, particularly on the shallow sea floor, and was driven by a combination of factors. These factors include increases in oxygen levels, the availability of new ecological niches, development of complex predator-prey relationships, and the evolution of new biological structures. The Cambrian Explosion resulted in the establishment of a rich and diverse biota, paving the way for further evolutionary developments in subsequent geological periods.

   The Cambrian Explosion is a crucial event for understanding the history of life on Earth, as it set the stage for the subsequent radiation and diversification of animal species. The study of this phenomenon helps scientists shed light on the evolution of complex life forms, the processes of speciation, and the exploration of ancient ecosystems.

Etymology of CAMBRIAN EXPLOSION

The word "Cambrian" in "Cambrian explosion" refers to the Cambrian Period, which is a geological period that occurred approximately 541 to 485 million years ago. It was named after Cambria, the Roman name for Wales, where rocks from this period were extensively studied. The period is known for the rapid diversification and proliferation of multicellular animal life.

The term "explosion" in "Cambrian explosion" was coined by American paleontologist Harry B. Whittington in 1960 to describe the sudden appearance of a wide array of complex animal forms in the fossil record during the Cambrian Period. It referred to the relatively short geological time span within which an extensive number of animal phyla emerged, displaying remarkable diversity and complexity. It should be noted that the term "explosion" represents the abrupt appearance of diverse forms instead of an actual explosion-like event.
