De första djurens hav och The Cambrian explosion or Cambrian radiation was an event approximately 541 million years ago in the Cambrian period when practically all major animal phyla started appearing in the fossil record. It lasted for about 13 – 25 million years and resulted in the divergence of most modern metazoan phyla. Cambrian explosion, the unparalleled emergence of organisms between 541 million and approximately 530 million years ago at the beginning of the Cambrian Period. The event was characterized by the appearance of many of the major phyla (between 20 and 35) that make up modern animal life.

The Cambrian Period was the beginning to the so called Paleozoic Era according to evolutionists using the so called Geologic Column for dating of rock strata. The Cambrian Period is at the bottom of this column. One explanation for the Cambrian explosion is that something changed in the physical environment. Perhaps it was a rise in oxygen levels, which allowed the respiratory requirements of larger The Cambrian explosion was a unique animal radiation ~540 million years ago that produced the full range of body plans across bilaterians. The genetic mechanisms underlying these events are unknown, leaving a fundamental question in evolutionary biology unanswered.

Denying Darwin: the Cambrian explosion One of several severe problems facing gradualists and Darwinists alike is the occurrence of what has come to be known as ‘the Cambrian explosion’ which took place around 530 million years ago. The Cambrian explosion has long been a basic research frontier that concerns many scientific fields. Here we discuss the cause-effect links of the Cambrian explosion on the basis of first Important in the current context is that the Burgess Shale fossils have increased the known variety of the Cambrian explosion, yet without predecessors showing how the diversity arose from common ancestors. So these important new discoveries have increased the challenge posed to evolution by the fossil record. 2018-05-17 · Cambrian Explosion.
