The Cambrian Explosion

The fundamental physical prerequisites of people , just like all organisms , are : water, for various metabolic process; foods, to provide energy, raw materials for developing entirely new living matter, as well as chemical substances required for vital reactions; oxygen, to discharge energy from foods materials; heat, to enhance chemical effects; and also pressure, to enable inhaling and exhaling” This like this article and think that it relates to . To be able to understand how humans evolved from early existence forms, we can quickly take a look at our closest relatives, the primates. Primates consist of us (Homo sapiens), the apes, the monkeys, as well as prosimians, for example, the lemur. We can easily be familiar with primate behavior

One of the biggest pieces of evidence for the Flood is the Cambrian explosion. The Cambrian explosion is taught by evolutionist to be a sudden burst of evolution caused by an increase in favorable environments. An evolutionist article states, “Fossils provide solid evidence that organisms from the past are not the same as those found today; they show a progression of evolution… The resulting fossil record tells the story of the past and shows the evolution of form over millions of years. For example, scientists have recovered highly-detailed records showing the evolution of humans and horses.” (Evidence of Evolution, n.d.) In reality the fossil record shows that there was a sudden and nearly simultaneous appearance of all known phyla as well as species from the most distant parts of the family tree during the Cambrian period, instead of a gradual evolution. (Wieland, n.d.) (Wise, 2009) Fossils have been found worldwide in Precambrian rocks, but they were too bizarre and different

All animals with limbs have a common design. If a batwing were to be formed from a person’s hand, make the fingers extremely long; a horse elongates the middle fingers and reduce and lose the outer ones; frogs elongate the bones of the leg and fuse several of them together. All in all, despite radical changes in what limbs do and what they look like, this underlying blueprint is always present.

The pelvis and spine tell you whether on organism walked upright or on all fours.

Despite the evolutionary many benefits and gradient expenses with human intelligence, increased brain size did not occur because it was able to expand by itself. Environmental factors are what led to the evolutionary changes. A fundamental principle of evolutionary theory is that evolution is the balanced outcome between costs and benefits. Since the price of maintaining a large brain is greater, it is inherently improbably that expansion of the brain will evolve without a selection factor being adequate to overcome the high expenses. (Dunbar, 2007) There has been a strong correlation between increased temperatures in the global climate and increased endocranial volume. Over the past three million years, the average global temperature has been steadily increasing, as well as the braincase of human ancestors. Strong evidence of this is seen between the period approximately 200,000 to 800,000 years ago where the Earth’s climate experienced the greatest temperature fluctuations which

Major Biological Event: Life evolved and diversified greatly during this Era, in an event called the Cambrian Explosion. Plants began to grow on the land and jawed fish began to appear. The first forests made of small trees and bushes forms, populated by insects, reptiles, amphibians. However, this Era ended with a max extinction in which 96% of the populus went extinct.

First, evidence from the hominid fossil Ardy and archaeological evidence from the same area where Ardy was found points to the evolution of bipedalism in a woodland environment. This goes against the previous assumption that bipeds adapted to a more desolate environment. Additionally, it was also previously believed that bipedalism started with organisms that walked on two legs and their knuckles as a today’s chimp walk. However, there is no evidence in Ardy’s bones that it ever walked using its knuckles. On the other hand, Ardy possesses a short, broad hipbone which allows for bipedalism, but also a much longer lower half of the pelvis which would be more useful for climbing. Consequently, while Ardy could walk on two legs, it could not walk as well as future bipeds such as the fossil Lucy or modern humans. Lucy is often described as “the ape who stood up” and is further down the evolutionary track toward modern humans. This evolutionary adaptation to stand and walk on two legs opened great doors for humankind. Most important was the fact that walking on two limbs rather than four freed up our very special hands and empowered humankind to build tools and reshape the world as no creature could

Evidence  for  life  on  early  Earth  (e.g.  in  the  Pre Cambrian)  has  proved  difficult  to  find  because: SELECT  ALL  THAT  APPLY Select  one  or  more: A.  rocks  from  these  early  times  are  rare  due to  the  recycling  of  the  Earth's  crust  through plate  tectonics   B.  there  was  no  oxygen  in  the  Earth's atmosphere  at  this  time C.  life  at  this  time  lacked  hard  parts  (such as  shells  or  bones)  that  fossilise  easily   D.  life  had  not  yet  emerged  onto  land E.  life  at  this  time  was  mostly  microbial

Could not explain the Cambrian explosion, all life forms appeared or disappeared, completely formed totally devoid of transitions.

Evolution is the key thread running throughout this text, signifying its importance to the author and readers. It is emphasized greatly because that is how we understand ourselves, our past, present and even the future. Through evolution we have discovered when the first organisms came around and how modifications led to the first fish to migrate to land about 375 million years

The Ardipithecus ramidus foot shows key characteristic features of bipedality. Whilst there is evidence to show support for bipedalism it is hypothesised that was an occasional form of locomotion used less commonly than arboreal methods. This can be seen through the

Some beasts slithered, some walked on all limbs while others flew and swam. There was also a very odd pair of beasts that had no fur or scales and walked on 2 limbs that would gibber and

Prud’homme et al. (2011) demonstrated that the wing specific gene nubbin was expressed in a similar pattern in the helmet formation as in wings and arrived at the conclusion that the treehopper helmet was serially homologous to the T1 wing. In addition the authors speculated that the evolution of the helmet is due to a change in an unknown genetic mechanism downstream of Scr (sex combs reduced), which is part of the hox gene family. Thereby suggesting that the evolution of the treehopper helmet is due to genes that were under repression by hox genes. Moczek (2011) speculated that the tree hoppers evolved a wing like structure through re- emergence of a repressed developmental program of the wing. Clark-Hachtel and Tomoyasu (2016) proposed that the treehopper helmet might be partially homologous to the wings based on the fact that the treehopper helmet and the beetle carinated margin of Tribolium beetle both originate from the T1 tergum and it was shown that the reduction of the repression of Scr lead to formation of wings in the beetle. Conversely Yoshizawa (2012), proposes that the lack of evidence for the Scr mechanism in treehoppers might be due to pleiotropy and

The word is now accepted to mean the change of nonliving chemicals into simple life-forms into more complex life-forms and finally into humans.” (Answers in Genesis 1). Despite the many claims that “evolution” simply means a change, scientifically speaking it means much more. Evolutionary ideals describe changes that allow scientists to date life on the earth to be 4.5 billion years, to trace the entire living population of every animal, insect, plant, virus, and bacteria back to one simple cell, and to conclude that the first cell supposedly came into being sporadically from a pool of organic molecules (Archean 1). Science cannot factually support evolutionary concepts because evolution cannot be tested; observation holds a critical role for experiments to take place, yet spontaneous creation of a cell has not recurred since the alleged first living cell created itself. Evolution cannot be proven, and therefore, the public school system should not teach evolution as fact, especially with no exposure to alternative concepts.

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, in order for the oxygen to be accumulated in the atmosphere, Iron and Sulfur like oxygen-sinks had to be depleted.
