What does radiometric dating prove regarding macro evolution? Answer. . What evidence did Darwin use to support his theory of evolution? Darwin had. Radioactive dating can provide supporting evidence for evolution. dating then can only be used to generally support the theory of evolution.

By half a billion years ago fish dominated the oceans, but the land remained barren.

Within 50 million years plants and insects made a foothold out of the water. The earliest amphibians ventured into this rich new, uninhabited niche around million years ago.

These amphibians are all remarkably similar to sarcopterygian lungfish of that era the Devonian. Sail backed reptiles populated the Permian. Their forms diversified into a wider variety of creatures during the Triassic.

Dinosaurs dominated the Jurassic and Cretaceous epochs. During this time, referred to as the Mesozoic, flowering plants including grasses were virtually unknown. The Cenozoic, the past 65 million years, is known as the age of the anthophyta flower plants. It is also known as the age of mammals, as terrestrial forms widely diversified during this period also.

Fossils provide clear and abundant evidence for the gradual adaptation of species to new environments all across the globe. Darwin's theory is considered extremely sound, and forms the foundation of biology. Indeed, famed biologist Theodosius Dobzhansky once explained that "nothing in biology makes sense except in the light of evolution.

A couple of years later, farmers have noticed that those insects have now started to feed off of apples. This farm used to be filled with cows and the farmer then sold all his cows to a milk company, so he got rid of the insect-infested hay that was the cows' food.

The farmer then started planting apple trees instead, and he had a lot of those insects in his area so after a while the insects correctly "adapted" to the fact that hay wasn't available and apples were, so that was proof for natural selection. The theory of biological Evolution includes the concept that? Chromosomes contain [biochemically] linear information that produces three types of proteins: How is radioactive dating important for providing evidence for evolution? Caused the living creatures to be capable of and interested in reproducing themselves.

Caused that life to spontaneously diversify into different forms of living things, such as the plants and animals on the earth today. Evolution has been accused of being the only process capable of causing the observed phenomena. As with any just court, the burden of proof rests on the accuser.

Most thinking people will agree: A highly ordered universe exist. At least one planet in this complex universe contains an amazing variety of life. Man appears to be the most advanced form of life on this planet. Choices of how the observed phenomena came into being: The universe was created by God. The universe always existed. The universe came into being by itself, by purely natural processes known as evolution.

How does radiometric dating add evidence to the theory of evolution

No appeal to the supernatural is needed. This might include the following: The earth is not billions of years old thus destroying the possibility of evolution having happened as it is being taught. No animal has ever been observed changing into any fundamentally different kind of animal. No one has ever observed life spontaneously arising from non-living matter. Matter cannot make itself out of nothing.

Most people feel that radiometric dating, having a reputation for scientific respectability, proves that the earth is many millions of years old, thus providing the time framework required for the theory of evolution to have plausibility.

As explained by physicist Walt Pasedag, radiometric dating uses the principle of radioactive decay, a physical process which can be measured with great precision. Radioactive decay is described by a simple mathematical relationship, which states that the amount of a specific isotope that remains in a sample declines exponentially with time, according to a fixed rate constant, the "decay constant" which is unique for the isotope.

Decay constants have been measured for all known isotopes ever since Madam Curie discovered radium in When the isotope decays, it turns into a different isotope, the so-called 'daughter' product.

By measuring the quantities of parent and daughter isotopes, the time that has elapsed to generate the measured amount of the daughter product can be calculated. As far as the technical aspects go, the process lives up to its reputation of great accuracy.

The decay time calculated from the measurements, no matter how precise, cannot be interpreted as the age of the rock the sample was taken from without making a number of assumptions, and that's where the problems arise.

The basic assumptions that need to be made are: In other words, there was no migration of isotopes, no leaching, influx, or chemical reaction which could disturb the balance between parent and daughter isotopes throughout the long time spans usually postulated. This assumption would be totally untenable for sedimentary rock, which, by definition, is formed by processes which would disturb this balance, so radiometric dating cannot be used for this type of rock.

Unfortunately, fossils, the other approach to dating rock, only occur in sedimentary rock. The above weaknesses of radioisotope dating are well known.

Less recognized, however, is an additional difficulty pointed out by geologist C. Allen Roy in an e-mail to a creation listserv.

Even if one minimizes the above-mentioned weaknesses and accepts the methodology of radioisotope dating as valid, it is still fraught with a subjectivity which disqualifies it as a truly scientific approach to dating rocks. He made three basic observations, which are summarized below. The data-gathering process is assumed to be objective We are given the impression that:
