Cambrian explosion

about seven-eighths of the entire earth’s history. This era stretches across from 4 Billion years ago up until only 543 Million years ago (Mya) which shows how large and substantial this era was. Precambrian itself refers to the time before the Cambrian period. It also refers to the entire period of time before the formation of the oldest rocks with recognisable fossils. Lately, however, it has been seen that some hard to distinguish fossils from in the Precambrian times have been found. The Precambrian

Era all life lived in or around water. This is because land was not sustainable for life yet.The Paleozoic Era had six different periods. The Era lasted about 542 million years but ended because of the Cambrian explosion. The first period in the Paleozoic Era was the Cambrian Period. The Cambrian Period was an important part of Earth’s history and formation. It was when mainly all of life first came around. The second period in the Phanerozoic Era was the Ordovician Period. During the Ordovician

Cambrian Room: This room would highlight the explosion of evolutionary changes in life on Earth. There would be displays of the animals that evolved; chordates, hard-bodied brachiopods, and arthropods. Also, due to the climate at this time being that Earth was generally cold the

1. a) What are the major global events that occurred in the Proterozoic? (3) Three global events occurred during the Proterozoic: The oxygen revolution: During the Proterozoic, biotic system were being established, which gave rise to biomass of the prokaryotic organisms like the “benthic and planktonic photosynthesizing organisms” Due to the vast developing diversity of environment, organisms could well adapt to these various environments, which increased the input of oxygen on Earth. Hence

Sean Carroll’s book Endless Forms Most Beautiful, attempts to explain the variety of animal forms, structures and functions by comparing them to rules that he had found. Such rules include: major “rules” for generating animal forms, species-specific encoding information, evolutionary diversity and large-scale trends in evolution. It begins by assessing the similarities between ancient and modern organisms. It notes that the structure of certain parts like vertebrates and limbs are similar in proportion

because I do think that we all come from one ancestor, except, I think we come from Adam. I do think that this argument has the most power to me because of its potential to be true. Although fossil records indicate something more similar to the Cambrian explosion stated in the book, Well’s did admit that he could not prove to Strobel that

Human Origin has been an argument that I have heard about when I was in public school. I learned about evolution at school and creation at home. I was never able to really argue for creation until coming to Southeastern University. I also never paid attention in class when we were learning about evolution because I knew that I did not believe it. Learning a lot in this class and others, now I believe that I would be able to start a conversation with people who believe in evolution and be able to

The Paleozoic era age approximately 300 million years (542 mya to 251 mya). This time period consists of two of the most important events in the history of animal life. In the beginning, multi celled animals underwent a dramatic explosion in diversity, this resulted in almost all living animal phyla appearing within a few million years. At the other end of the Paleozoic, it withstood the largest mass extinction in all of history. This event wiped out approximately 90% of all marine animal species

Bill Nye VS. Ken Ham Rain Shi Ken Ham is a Christian who established a creationist museum, he insisted the Earth still young. Ken Ham said: "Today, there is too much influence of the theory of evolution on children, we need to take the child back to the correct view of the world in this debate, and it is a good opportunity to let people know more about God, and the spread of the Gospel. " Ken Ham 's position is creationism. He believes that people are not evolved, because God created human, and

then five million years’ worth of creating different organisms, and then five hundred million years of variation of anatomical organisms. Most phylum of animal life made their star debut on fossils everywhere in what is known as the Cambrian explosion. This explosion established anatomical design of animal life at a rapid
