How is radioactive dating important for providing evidence for evolution

It tells you how old fossils are. To accurately gain information upon whether the globe truly is warming up, one must check many sources of data from a variety of sources. CO2 levels over the years can be recorded from drilling into ice, tree rings can tell us a bit about temperature over the years, the sources are quite numerous and all seem to suggest that there is a continued warming of the planet.

If one example is requested, I would note the continued loss of ice at the poles. There can be no better evidence than the temperature records themselves. The year had the warmest global average temperature on record, fractionally warmer than and , but as the difference is slight, the three years are regarded as the equal hottest.

The past decade was the warmest since instrumental measurement began in , and the ten warmest years since have now all occurred since View all of them. You will have your answer and proof. What evidence proves that Earth is round? Pictures from space for one, the laws of gravity for two and the curved horizon for three - not to mention the planes that fly and ships that sail around the world on a regular basis.

Not only that, but now that we have access to space, the easiest way to prove the Earth is spherical is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape and the only geometric solid which looks like a circle from any direction is a sphere.

The geometry of a lunar eclipse has been known since ancient Greece. Every time that shadow is seen, its edge is round. Once again, the only solid that always projects a round shadow is a sphere. What does radiometric dating prove regarding macro evolution? Off the top of my head it substantiates that if you have 5 transitional fossils showing the slow change of an organism over a few million years that they did come in the order that they appear to, that one did spawn the other.

I think the best evidence of macroevolution is in genetic similarities between all life on earth, common descent. Radiometric dating proves nothing about any form of evolution since it is itself unreliable in the sense that it is based on three unprovable assumptions, and has also been found to be unreliable in the field in various circumstances.

Has evolution been proved to be right? Yes, evolution has been proven true. Richard Lenski has been very precisely observing twelve cultures of E. Before anyone starts bragging about the E. The end result, after 50, generations of breeding, with the experiment only proved life will find a way.

After 50, generations of E. Humans were known as Homo erectus. Neanderthals were walking around. And after 50, generations We are still missing some key piece of evidence for the validation of evolution.. Evolution is spectacularly evidence-supported. Evolution has no refutation. Note how pedantic this.

Evolution is correct and is accepted by all respectable scientists who accept it due to its evidence.. What are facts that can prove evolution is not real? Cave gave a paper at the International Congress ofZoology in in which he concluded that a skeleton found inFrance was not an Neanderthal but was of an elderly human whosuffered from arthritis.

The implication is that Neanderthals neverexisted. Practicable application of growth rate throughout human historywould be about half that number. Wars, disease, famine, etc. However, application on an evolutionary time scale runsinto major difficulties. Starting with one "couple" just 41,years ago would give us a total population of 2 x Is there evidence that proves bigfoot exists?

There is evidence Bigfoot exists. Eusthenopteron is a link in a chain of evidence supporting evolution. Transitional forms have been found that are elements of its development from a fish that lived entirely in the ocean to the tetrapods that walked on land. These progressive changes spanned million of years in the late Devonian, from the fish Eusthenopteron , through Tiktaalik , and Acanthostega , to the oldest known tetrapod, Ichthyostega..

Eusthenopteron was fish in the ocean, but a portion of that ocean became landlocked and is now part of Pennsylvania.. One of them is described by Ilya Prigogine. Does Archaeopteryx prove evolution? By itself, the Archaeopteryx, an extinct link between dinosaurs and modern birds, probably does not "prove" evolution.

Persons who believe literally in biblical creation could still say that God created this strange creature, but that for some reason Noah failed to take it onto the Ark, and it became extinct. To say that, they have to also claim that the Archaeopteryx lived only a few thousand years ago, thus meaning that scientific methods were wrong when they proved Archaeopteryx fossils to be millions of years old, although those same scientific methods are reliable when they are used for all other purposes.

The commonly held view among vertebrate paleontologists is that while Archaeopteryx was a true bird and certainly evolved from dinosaurs, it was probably not the ancestor of modern birds. Fossil evidence now available shows that some dinosaurs did not have reptilian scales but instead had feathers for warmth and to help them turn their huge bodies in pursuit of nimble prey, readily leading to the use of feathers for flighted descendants like Archeopteryx.

It had teeth and a long bony tail, features it inherited from its dinosaur ancestors but lacking in modern birds. Several of the specimens were initially misidentified as dinosaurs, so closely does archeopteryx resemble the dinosaurs from which it evolved. The fossils there are 11 so far almost beg the question, "if evolution is false, why are there specimens so highly evocative of the process?

An early specimen of Archaeopteryx had a crushed skull, leading to some wrong conclusions. Now that more specimens have been found and analyzed, scientists generally agree that Archaeopteryx was a bird, and a transitional form for the following reasons: It had avian feathers fully formed, not at all like scales.

Avian lungs, clearly quite different from reptiles which have bellows-like lungs. Classical elliptical wings like modern woodland birds. Large wishbone for attachment of muscle necessary for strong downstroke for flight. A modern avian brain size, 3 times the size of an equivalent dinosaur, including large optic lobes for data processing during flight.

In most vertebrates, as also in reptiles the lower jaw mandible moves, but Archaeopteryx is like birds in that the lower jaw could move as well. Archaeopteryx had a grasping hallux , or hind toe, which pointed backwards and it had curved claws for perching like birds and unlike dinosaurs. The premaxilla does not have a keratinized covering, so Archaeopteryx has no bill. Trunk region vertebra are free. In modern birds the trunk vertebrae are always fused. Pubic shafts with a plate-like, and slightly angled transverse cross-section, a trait shared with dromaeosaurs but not with other dinosaurs or birds.

Neck attaches to skull from the rear as in dinosaurs not from below as in modern birds. Center of cervical vertebrae have simple concave articular facets. This is the same as the archosaur pattern. In modern birds the vertebrae are different, they have a saddle-shaped surface. Long bony tail with many free vertebrae up to tip. Modern birds have a short tail and the caudal vertebrae are fused to give the pygostyle.

Ribs slender, without joints or uncinate processes and do not articulate with the sternum. Modern birds have stout ribs with uncinate processes braces between them and articulate with the sternum. Pelvic girdle and femur joint is archosaurian rather than avian except for the backward pointing pubis. The Sacrum the vertebrae developed for the attachment of pelvic girdle occupies 6 vertebra. Metacarpals hand free except 3rd metacarpal , wrist hand joint flexible. Nasal opening far forward, separated from the eye by a large preorbital fenestra.

Deltoid ridge of the humerus faces anteriorly as do the radial and ulnar condyles. Claws on 3 unfused digits. The fibula is equal in length to the tibia in the leg. Metatarsals foot bones are free. In modern birds these are fused to form the tarsometatarsus.

Gastralia are "ventral ribs," elements of dermal bone in the ventral wall of the abdomen. Typical of reptiles, they are absent in modern birds. Thus the conclusion that Archaeopteryx is intermediate is clear from the evidence. It is a bird and was so regarded by the International Archeopteryx Conference held at Eichstatt in Germany in As a side note, Archaeopteryx, is not regarded as a transitional form by Alan Feduccia, himself an evolutionist.

But it is not. It is a bird, a perching bird. Why do fossils prove that evolution has occurred? Fossils themselves prove nothing. However, in comparing fossils from earlier, later and much later times, we see such similarlities accompanied by differences; we see creatures remaining as they were, and then suddenly developing into others, sometimes disappearing, soemtimes living alongside them.

The fossils show us a small picture of basically what was alive at that time.


Aug 13, аи Best Answer: Fennec, Radiometric dating, by itself, is not necessarily evidence for evolution. But together with fossil samples that have been gathered from rocks that have been radiometrically dated, it is powerful evidence for evolution. The radiometric dating of the geologic column, by itself, does not Status: Resolved. Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which .
