Transitional fossil

Organic archaeological specimens, matter that was once living, such as bone, shells, skins, fibers, wool, etc., are all dated by use of radiocarbon dating (anything that once lived). The radiocarbon dating process measures the Carbon-14 isotopes within the organic material being examined. This method measures the radioactive emissions from the once living matter, comparing its activity with the equilibrium level of living things, a measurement of the time elapsed can be made. The radioactive isotope

Scientists use the Law of Superposition, the Principle of Cross Cutting Relationships, index fossils, radiometric dating, and the Geologic Time Scale to organize Earth’s 4.6-billion-year-old history. The Law of Superposition is the law that states that in layers undisturbed rock, the older rocks will be closer to the bottom and the younger rocks will be near the top. This is a helpful method used by scientists to organize earth's history. Our Law of Superposition Worksheet showed how there were

and animals are ideal to live and survive upon. Also the environment, in which they are made, doesn’t destroy the fossils and they preserve them. In 2004, the fossils were found on Ellesmere Island in Northern Canada. This location was chosen because this is the place where there are no humans or roads or any disturbance that would forbid them to dig anywhere they want. 2. The fossil of Tiktaalik confirmed a major prediction of paleontology as it shows the characteristics

Introduction According to scientists, one of the most extraordinary bursts of evolution ever known was the Cambrian Explosion. For most of the nearly 4 billion years that life has existed on Earth, evolution produced little beyond bacteria, plankton, and multi-celled algae. Then, about between 570 and 530 million years ago, another burst of diversification occurred. This stunning period is termed the "Cambrian explosion," taking the name of the geological age in which the earlier part occurred. A

(represented by error bars) increases from about 0.2 ‰ to 0.8‰ in δ13C values, and 0.3‰ to 0.9‰ in δ18O values as the taphonomic number increases. If this relationship is universal, it represents a significant impact on the records acquired by damaged, fossil or recent shells. As stated in the introduction some studies have examined the impact of

of Australian fossils contributes to the development of understanding the evolution of species in Australia in many different ways, such as seeing changes in physical appearance of species, and possible reasons why the species evolved into what they did, when and why a certain species may have become extinct and evidence/proof of theories such as natural selection. Each of these goes hand in hand and helps us find out what our Earth would have been like millions of years ago. Fossils are the remains

Introduction A man by the name of Charles R. Darwin published a book that was titled On the Origin of Species by Means of Natural Selection, or the Preservation of Favored Races in the Struggle for Life, (typically called The Origin of Species). Published in 1859, this book caused a great dispute in the world of science. You see, in his book Darwin was just trying to answer an age old question “How Did We Get Here?” without ever referring to a supernatural creator. This book shocked the science community

this essay is to identify the evolutionary evidence of speech. The articles reviewed in this paper affirm the evidence of evolution of speech. Much is unknown about the evolution of speech, however, fossil evidence points to adaptations for speech appearing between 1.5 million and 500,000 years ago. Fossil evidence for the evolution of speech is shown in the earliest hominins to one of our well known ancestors, the homo erectus. There are differences between bone structure and hard tissues of living
