What is the relationship between fossils and evolution?
evolution. - Fossils are the remains of living things which are found in sedimentary rocks. These rocks form in layers so animals and plants can get trapped between the layers. - When palaeontologists compare fossils to animals from today, they can see similarities and identify relationships between them. - Living things also provide evidence
What do fossils tell scientists about evolution?
Significance of fossils:
- Fossils are direct evidence in support of evolution.
- Living forms with simple organization appeared earlier than complex forms.
- The complete fossil history of many animals indicates the transition from an earlier simple to a later complex form.
- The process of fossils formation is called fossilization.
How can fossils help support the theory of evolution?
Fossils support evolution because we see that there are organisms that did not exist THEN that exist NOW, and organisms that exist NOW that did not exist then. Fossils support evolution because sooner or later one of the fossils will look like a “missing link” you would like to see. They don’t. They support evolution.
How do fossils provide evidence that evolution has taken place?
How does the fossil record provide evidence for evolution? Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
How long does it take for a fossil record to support evolutionary theory?
The field of paleobiogeography uses the fossil record over billions of years along with geographic evidence to support evolutionary theory.
Why do scientists use molecular analysis?
Modern day studies include the use of molecular analysis to corroborate findings suggested by evidence in the fossil record. This technology has allowed scientists to understand where species first evolved on Earth back when the supercontinent Pangea was the only land mass on the planet.
What is the study of living things?
Biogeography is the study of the distribution of living things and how they are effected by abiotic factors like oceans, rivers, mountains, valleys and climate. Broadly, the theory of evolution is supported by biogeography through evidence such as the species on Earth being distributed around the planet based on their genetic relationships to each other. The field of paleobiogeography uses the fossil record over billions of years along with geographic evidence to support evolutionary theory.
Where did perching birds first evolve?
For example, work in this field has shown that perching birds first evolved in the area where Australia and Antarctica were once joined. Also, scientists have learned that many species of fish in the Amazon evolved as a result of allopatric speciation, but not all at once.
What is fossil record?
In short, fossil records provide a large part of the information that is needed to determine the distributions and the past interactions of the world. Therefore, fossil records or fossils actually provide us with a glimpse into the past where common ancestry is proposed to have taken place. These fossils may appear very simple at the beginning. yet over time with the base been updated with various kinds of new discoveries the characteristics and the connections it tends to have become more complex. Moreover, it is being revealed that the characteristics of newer organisms frequently appear to be modified forms of characteristics of the older organisms.
What is the order of development for the major types of vertebrate animals?
The anatomy and biochemistry of living species imply that the general order of development for the major types of vertebrate animals was fish into amphibians into reptiles and reptiles into mammals.
What is historical biogeography?
Historical biogeography – concerned with the origins and evolutionary histories of species on a long-time scale.
Which theory is supported by Alfred Wagner?
Likewise, over the years many evidence have been gathered to prove Charles Darwin’s evolution theory in a combination or with the support of Alfred Wagner’s Continental Drift theory, with the support of this biogeography fossils.
Is evolution possible?
According to the German geophysicist Alfred Wagner’s theory of Continental drift , the so-called evolution theory is possible. The continental theory compromises of a land called Pangaea. The five continents that we see today were together as one land. As a result of the evolution process, they have been dispersed into different continents, over time.
Why are fossils considered evidence of evolution?
It’s because fossils document the existence of now-extinct species that are related to the present-day species. Fossils indicate the gradual evolution and prove that organisms from the past are not the same as those found today.
Why are fossils important?
Fossils are important evidence for evolution because they show that life on earth was once different from the life that is found on earth today. A fossil is just the preserved remains of a dead organism from millions of years ago.
Why are microevolutionary changes not often observed in fossil records?
It’s all because the processes that govern evolutionary changes within species are thought to occur over much shorter time scales that simply can’t be determined studying the strata layers.
How do fossils show life?
Fossils shows how life originated from a very simple form to the present day more complex form. Fossil markings present in rocks of all ages shows how the simplest organisms are found in the oldest layers of rocks, and fossils of more complex organisms in the newest layers of rocks.
How are fossils ordered in strata?
The fossils that are seen in different strata layers are ordered by their positions in accordance to the geological timeframe.
What are trace fossils?
The trace fossils are the ancient markings of an organism that include footprints, tooth marks, burrows, and faeces ( coprolite). These provide indirect evidence of ancestral forms. The examples of trace fossils represent activities that occurred while the animal was alive like their tracks, burrows, eggshells, nests, tooth marks, ...
How to understand how old an organism is?
In order to understand how old an organism is, we need to study its fossils. And, in doing so, we need to understand the timeframe of each rock where the fossil is seen. Over the passage of millions of years of history, the rocks forms new layers above the previous ones. These layers are actually termed as strata.
The Fossil Record: The History of Life
The fossil record may be thought of as the ‘history book’ for life on Earth because it contains remains of Earth’s life from when it first appeared roughly 3.8 billion years ago up to the modern day.
Transitional Fossils
So-called ‘transitional’ fossils are intermediate fossils between different groups of organisms that possess traits of both groups. These fossils provide strong evidence for evolution because they demonstrate one group of organisms changing into another.
Extinction
Another piece of evidence for evolution provided by the fossil record lies in the total number of species that have lived on Earth.
How Do Fossils Provide Evidence for Evolution?
Many veins of evidence support the theory of evolution, but one of the most important is the fossil record. The fossil record paints a dynamic picture of the history of life on Earth.
What are living fossils?
Living fossils are the fossils of species that have not died out to this day and they are not different from their present forms despite being millions of years old. Evolutionists pay the utmost attention to avoid mentioning these fossils. Although we can show a lot of examples to these fossils, we will make do with a few of them for the time being. On the left is a 450 million-year-old horseshoe crab fossil, and on the right is a contemporary horseshoe crab. Evolutionists claim that human evolution from ape-like creatures took place in a few million years. If a few million years can create such a dramatic evolutionary change, evolutionists have to account for how come this creature has not gone through any visible change during the course of 450 million years.
How old are human fossils?
The human fossils that were found in Nigeria are quite ancient-looking despite being only 13,000 years old. Homo erectus is claimed to have died out 200,000 years ago but these fossils resemble Homo erectus more than they resemble modern humans despite being only 13,000 years old. These fossils are usually swept under the carpet for not conforming to the timeline of evolutionists.
What is the difference between Homo sapiens and Neanderthals?
They were thus propagated to ignorant people by every means possible. They later realized that Neanderthals were not as stupid as they thought them to be but still, they considered them less intelligent than Homo sapiens. Now, evolutionists admit that there is no difference between Homo sapiens and Neanderthals in terms of intelligence and skills. Moreover, they now admit that Homo sapiens and Neanderthals interbred, even though the definition of “species” rules out the possibility of interbreeding and producing fertile offspring with another species. This leads us to the conclusion that Neanderthals are not a discrete species; they should be regarded as a race within Homo sapiens. We do not criticize the update of scientific knowledge, what we criticize is making unfounded speculations out of pure imagination and presenting these as scientific facts. Why were Neanderthals presented as primitive and unintelligent in the first place when they had larger brains than Homo sapiens on average?
What fossils show that all Homos were actually Homos?
Do not ever think that these deceptions were things of the past. A recently-found Homo erectus fossil once more shocked evolutionists. This fossil dates back to 1.8 million years ago and it showed that all Homos living at that time were actually Homo Erectus. The species Homo rudolfensis, Homo gautengensis, Homo ergaster, and Homo habilis were supposed to live at that time according to the human-evolution timeline proposed by evolutionists. However, the difference between this new Homo erectus fossil and an average Homo erectus was more than the difference between the above-mentioned four species and an average Homo erectus. [3] The result is crystal clear: In order to close out the missing links in the scenario of human evolution and to make the huge leap between the genus Australopithecus and the genus Homo easier to explain, evolutionists have made up the species Homo rudolfensis, Homo gautengensis, Homo ergaster and Homo habilis that are assumed to have lived between these two genuses, whereas indeed the fossils assigned to these four species are all Homo erectus fossils. Today, all humans are considered Homo sapiens although we have significant differences with each other (for example, African pygmies have an average male height of 1.5 meters while there are nations with an average male height of 1.9 meters). Intra-species variation is often misinterpreted by evolutionists in the sense that they classify the individuals of the same species that have different characteristics as different species. There are significant physical differences (including the skull shape) between different human races living today. If the fossil of the Russian boxer Nikolai Valuev were found today, evolutionists would liken it to Neanderthals and classify him as a different species although he is Homo sapiens as much as we are.
What is the fossil of Piltdown Man?
The fossil of Piltdown man gained incredible fame when it was found in 1913 and scientists endorsed that it is a missing link in human evolution . In 1953, Piltdown man was proved to be a hoax: its skull belonged to a human being and its jaw belonged to an orangutan. These two parts were stained with chromium and acid iron sulfate solution in order to give the impression of ancientness. This incident is regarded as one of the most successful hoaxes in the history of science.
Do fossils prove evolution?
The subject of fossils is one that both evolutionists and creationists lay claim to and bring up as evidence for their side. I neither find the argument of “there is no transitional fossil that demonstrates evolution” of creationists nor the argument of “fossils prove evolution” of evolutionists sensible. Fossils are like concrete dots, and how to abstractly connect these concrete dots is up to us. Even evolutionists differ in connecting these dots and they propose different stories of evolution. For example, today there are fishes at the bottom of seas that have legs on which they walk. A distant-future paleontologist that will research our century and find the fossils of these legged-fishes may come to the false conclusion that all land animals evolved from legged-fishes in the 21st century. Today, there is a species called “flying fish” which has wings that it can use to fly for short distances. A distant-future paleontologist that will research our century and find the fossils of these winged-fishes may come to the false conclusion that all birds evolved from winged-fishes in the 21st century. There would be no evidence disproving these conclusions although they both are incorrect. A distant-future paleontologist that will research our century and find the bones of a man buried along with the bones of his pet –let’s say a dog- due to an earthquake may not differentiate between their bones and think that humans had doggy features back in the 21st century. If a distant-future archaeologist were to dig and find the remains of New York, he would think that humans had an advanced civilization in the 21st century; but if he were to dig and find the remnants of an African tribe, he would think that humans were quite primitive in the 21st century. As these examples illustrate, it is impossible to make certain deductions from fossils and archeological findings.
Where do fossils occur?
15- Fossils occur on continentals, not deep ocean bottoms.
Who are the two evolutionists who admitted the pseudo-scientific, philosophical origin of Darwin's view?
In their journal disclosure, evolutionists Stephen Jay Gould and Niles Eldridge have honestly admitted the pseudo-scientific, philosophical origin of Darwin’s view by their candid confession that “Phyletic gradualism [gradual evolution]… was never ‘seen’ in the rocks ….
What is the fossil record of the Cambrian Explosion?
Rather than animal kinds coming about by natural selection somehow adding new genes and organs to pre-existent ancestors as Darwin’s ideas predicted, the fossil record provides no hint in the lowest known fossil-bearing rocks (named “Precambrian” and “Cambrian”) of single-celled organisms morphing into the multi-celled creatures. The “Cambrian Explosion” describes the sudden appearance of all the radically-different blueprint types of each animal all in one rock system. This gap—which occurs globally—should not even exist locally if evolutionism is true.
What evidence does Darwinists believe in?
Darwinists, however, interpret the fossil record, or the remains of past life found within the rocks of the earth’s crust as circumstantial evidence that biological species originated by natural selection from a universal common ancestor.
How many fossils are there in museums?
Werner concluded: “Now, 150 years after Darwin wrote his book, this problem still persists. Overall, the fossil record is rich—200 million fossils in museums—but the predicted evolutionary ancestors are missing, seemingly contradicting evolution.” [xi] He gives a series of examples:
How many dinosaurs have been found?
1-Museums have collected the fossil remains of 100,000 individual dinosaurs, but have not found a single direct ancestor for any dinosaur species.
Does the fossil record support all evolutionary expectations?
The fossil record falsifies all three evolutionary expectations. Instead, the fossil record biologically, paleontologically, and geologically supports all Creation and Flood expectations. We evaluate these three next.
What Is The Fossil Record?
Fossils and Converging Evidence
- That the fossil record, in general, suggests evolution is certainly an important piece of evidence, but it becomes even more telling when it is combined with other evidence for evolution. For example, the fossil record is consistent in terms of biogeography— and if evolution is true, we would expect that the fossil record would be in harmony with c...
Fossils and Scientific Predictions
- We should also be able to make some predictions and retrodictions as to what we would expect to see in the fossil record. If common descent occurred, then the organisms found in the fossil record should generally conform to the phylogenetic tree — the nodes on the tree at which a split occurs represent common ancestors of the organisms on the new branches of the tree. We would predi…
The Fossil Record: The History of Life
- The fossil record may be thought of as the ‘history book’ for life on Earth because it contains remains of Earth’s life from when it first appeared roughly 3.8 billion years ago up to the modern day. As such, the fossil record tells us when organisms evolved, when they went extinct, where and how they lived, what their habitats were like, and much more. Additionally, the fossil record t…
Transitional Fossils
- So-called ‘transitional’ fossils are intermediate fossils between different groups of organisms that possess traits of both groups. These fossils provide strong evidence for evolution because they demonstrate one group of organisms changing into another. To illustrate this point, let’s look at some examples from the fossil record. In this post, we will cover Archaeopteryx, Tiktaalik, and D…
Extinction
- Another piece of evidence for evolution provided by the fossil record lies in the total number of species that have lived on Earth. Although the Earth currently supports up to millions of species, many more have lived in the past. In fact, scientists generally agree that 99.9%, or 999 out of every 1000 species, have gone extinct. To reach such an estimate, scientists use a variety of m…
How Do Fossils Provide Evidence For Evolution?
- Many veins of evidence support the theory of evolution, but one of the most important is the fossil record. The fossil record paints a dynamic picture of the history of life on Earth. The fossil record demonstrates that life on Earth changes over time. Further, it provides transitional fossils, which are intermediates between two taxa. Finally, it ...
