Fossils: The Evolution World

There are a lot of misconceptions while talking about fossils. Fossils are not limited to the remains of a once living thing, but rather the evidence of life that existed in the past. This means that a fossil can be a dinosaur footprint, the form of a body on dry mud, bones, etc.

What is evolution? Evolution in modern terms is fairly easy to understand. Evolution is the theory that life on earth began with a single celled organism that lived more that 3.5 billion years ago that slowly evolved into

We use fossils to compare and contrast how and organism has evolved over a long period of time and how it has adapted to new changes.

Evolution: the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

Evolution is when an organism or something evolves over an extended period. An example of evolution would be humans because it took a long time for early humans to evolve into modern humans.

What is evolution? Evolution is a change in the traits of living organisms over generations. Since the development of modern genetics in the 1940s, evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation

It is important because it was almost a missing link to evolution. Therefore, it could have falsified evolution. The kind of rock’s we’re very old which was the best place to look for the fossil that was also very old.

Evolution is the change in the inherited characteristic of biological populations over successive generations (Wikipedia). The most notable theory of evolution was Charles Darwin’s speculation about natural selection. Natural selection is the process by which nature rewards those individuals better adapted to their environments with survival and reproductive success, defined by Ker Than, a Senior Editor in TechNewsDaily on livescience.com. Darwin published the first edition of “The Origin of Species” in 1859, in which Darwin theorized how a bear can turn in to a whale by natural selection. "I can see no difficulty in a race of bears being rendered, by natural selection, more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale," Darwin speculated (Than).

The word evolution means the process of change over a period of time. For example: plants and animals evolve over time by their genetic system allowing them to adapt to different changes in the world. The theory of evolution states animals, insects, plants, humans, and etc are all from a one-celled ancestor. A bad example of evolution is having a bad diet, which does not pass on to your next generation.

Fossils provide a record of how organisms have evolved overtime, as they contain the remains of life trapped in sediment, ice or amber and preserved for over millions of years. Transitional fossils, which provide evidence for evolutionary change, have features that show the transition of characteristics of organisms from ancestors to descendents. An example is Archaeopteryx, which featured reptilian features, including teeth and skeleton, however, also had feathers and a wishbone sternum (used to attach muscles for flying). The evidence of the fossil shows the evolutionary transition between dinosaurs and

The author and his colleagues chose to focus on 375 million year old rocks in their search for fossils because amphibians that look dissimilar to fish were discovered in 365 million year old rocks, while fish without amphibian characteristics were discovered in 385 million year old rocks. Thus, it is possible that the evolutionary intermediary, or the “missing link” between fish and amphibians, would be discovered in 375 million year old rocks, between the two time periods. The rocks examined were sedimentary in composition, as the gradual and relatively gentle formation of sedimentary rock under conditions of mild pressure and low heat are conducive to the fossilization of animal remains. Sedimentary rock is also often formed in rivers and seas, where animals are likely to live. This site provides a resource that describes means by which fossils are formed and how the fossil record may be interpreted, and shows some examples of fossils demonstrating evolution through geological periods: http://www.fossilmuseum.net/fossilrecord.htm. In 2004, Shubin and his colleagues were looking for fossils on Ellesmere Island, in northern Canada. This location was chosen because of its lack of human development, as well as of obstructing natural formations and life forms such as trees, which

Evolution is a change over time in species to adapt to new environments. Evolution has been a known fact now, but not all people believe in it. Some believe that evolution is a myth, or a lie. There is evidence that evolution is real.

Anatomy. Physically shared features can often be traced to a common ancestors following homologous structures such as the bones of animals(Khan Academy, 2018), or common embryonic vestigial features (OpenStax College, 2013 p. 488) such as a tail and gill slits in human embryos.

: Fossils are the remains or traces of ancient organisms which have been preserved. For example, a fossil can exist as skeletal remains or even as a footprint. Such organisms are subjected to a slow rate of decaying since they have been rapidly buried under conditions that facilitate this. It is common for fossils to occur as hard-bodied organisms as these are more resistant to environmental influences. Fossils are usually found embedded in rock. The layers of rock are of different age and makeup. Hence fossils found in one layer would vary in characteristics from those found in another layer. They can be observed and analyzed through visual as well as radiometric means so that the age and morphology can be determined. These features indicate

Evolution refers to change over time as species modifies and separate to produce several offspring species.
