    (1987), the Precambrian-Cambrian boundary is located in-between Ediacaran Fauna, which is found somewhere between 620-700 million years ago and trilobites, such as the fallotospid group. This creates a period ranging between 30-50 million years in which we can define the Precambrian-Cambrian boundary, making it difficult

    history, over the past 600 million years can be observed at Hallett Cove. Some of the oldest rocks have been found in these seas. The finding of the Ediacaran could potentially mean that there can be dinosaur fossils found in the ocean, or even that relatives of the ediacaran could be considered fossils and could be found in the sea. Although the Ediacaran period was well before the first appearance of dinosaurs it shows that there were fossils many years ago. When dinosaurs first appeared things had

    The Evolution of Animals Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists? Proterozoic Protists A single-celled eukaryote or protist can carry chlorophyll (it can be an autotrophic, photosynthetic, "alga"), it can eat other organisms (it can be an organotrophic, "protozoan" "animal"), or it may do both

    millions of years although it is described as rapid in geological terms. In this period of time, the Earth saw the rapid appearance of a wide variety of animals. Ecosystems became much more complex in the Cambrian Period to those that were seen in Ediacaran Period. As the variety and number of new organisms increased, they started to occupy new marine habitats and environments. Cambrian seas saw many animals of different shapes and sizes; some lived on the sea floor while others swam in the water. Early

    basic, made out of individual cells occasionally sorted out into colonies. The Cambrian explosion can be said to happen in waves. The initial, a co-evolutionary transformative ascent in differing qualities as animals investigated specialties on the Ediacaran ocean bottom, trailed by a second development in the early Cambrian as they established in the waters column. The pace of advancement found in the Cambrian times of the explosion is not paralleled amongst the marine creatures: it changed all metazoan

  • Essay about The Cambrian Explosion: Proof of ID?

    2084 Words  | 9 Pages

    The Cambrian Explosion: Proof of ID? In our studies of Intelligent Design (ID) theory and Creation Science, I found little information that seriously challenged the theory of evolution. However, there was one event that appeared to defy the logic of Darwinian gradualism: the Cambrian Explosion. This event was presented by ID theorists as proof of design--something which science is unable to account for. Unfortunately for ID proponents, this is not the case. There
