Human evolution

Important We believe any unbiased reader will realize that we were fair with our treatment of the two models in the table above. Yet, although the theory of evolution matches the facts in some cases, evolution is still an unproven theory. By now, you may believe it should be your first choice also. Unlike many others that preceded us, we attempted to find a clear defense of evolution for two reasons: To keep from being accused of bias. To keep from making claims that someone could refute later. Even though there are a great number of claims in books and on the Internet, we could find no scientific, testable facts that support the theory of evolution. The best site we could find was at The University of California at Berkeley. If you are interested, click here to examine the scientific evidence recorded at UC Berkeley yourself.

Radioisotopes and the Age of the Earth (RATE)

Genetic data based on molecular clock estimates support a Late Miocene ancestry. Various Eurasian and African Miocene primates have been advocated as possible ancestors to the early hominins, which came on the scene during the Pliocene Epoch 5. Though there is no consensus among experts, the primates suggested include Kenyapithecus, Griphopithecus, Dryopithecus , Graecopithecus Ouranopithecus , Samburupithecus, Sahelanthropus, and Orrorin.

Kenyapithecus inhabited Kenya and Griphopithecus lived in central Europe and Turkey from about 16 to 14 mya. Dryopithecus is best known from western and central Europe, where it lived from 13 to possibly 8 mya. Graecopithecus lived in northern and southern Greece about 9 mya, at roughly the same time as Samburupithecus in northern Kenya.

Creation With acknowledgement to Dr. Walt Brown, Center for Scientific Creation 1. It is an established scientific fact that life cannot originate from non-living matter the Law of Biogenesis. The chemical evolution of life is impossible. No scientist has ever advanced a testable procedure by which this could occur. The Miller-Urey experiment, still shown in many current textbooks, has been proven to be irrelevant.

Mendel’s Laws of Genetics limit the variations in a species. Different combinations of genes are formed, but not different genes. Breeding experiments and common observations have also confirmed that genetic boundaries exist. Acquired characteristics cannot be inherited. For example, the long necks of giraffes did not result from their ancestors stretching their necks to reach high leaves, nor does a man in a weight-lifting program pass his well-developed muscles on to his child.

No mechanism exists whereby the altered behavior of an organism, in an attempt to adapt to its environment, will produce a genetic change in its offspring. Genetic mutations have never made a creature more viable than its ancestors.

CREATION-EVOLUTION ENCYCLOPEDIA

Human Evolution Evidence Evidence of Evolution Scientists have discovered a wealth of evidence concerning human evolution , and this evidence comes in many forms. Thousands of human fossils enable researchers and students to study the changes that occurred in brain and body size, locomotion, diet, and other aspects regarding the way of life of early human species over the past 6 million years.

Millions of stone tools, figurines and paintings, footprints, and other traces of human behavior in the prehistoric record tell about where and how early humans lived and when certain technological innovations were invented. Study of human genetics show how closely related we are to other primates — in fact, how connected we are with all other organisms — and can indicate the prehistoric migrations of our species, Homo sapiens, all over the world. Advances in the dating of fossils and artifacts help determine the age of those remains, which contributes to the big picture of when different milestones in becoming human evolved.

Radiometric Dating Does Work! Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds for example, Arndts and Overn ; Gill but such attempts invariably have fatal flaws see Dalrymple ; York and Dalrymple Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.

In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze for example, Woodmorappe ; Morris HM ; Morris JD Only rarely does a creationist actually find an incorrect radiometric result Austin ; Rugg and Austin that has not already been revealed and discussed in the scientific literature. The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.

First, it provides no evidence whatsoever to support their claim that the earth is very young. If the earth were only —10 years old, then surely there should be some scientific evidence to confirm that hypothesis; yet the creationists have produced not a shred of it so far.

How Science Figured Out the Age of Earth

There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old.

We, the course organisers hope that you will find it both interesting and enjoyable – but unfortunately, before you can really get to grips with the fun stuff, you will need some background theory. The course is about human evolution. This means that at some stage, preferably fairly early on, you need to have some idea about evolution, and it’s also helpful to have an idea what we mean by “human”.

The first half of this lecture is an introduction to the central ideas of evolution, and the second half is about how we group up animals, including humans, so that we all know what we are talking about when we talk about them. Discussion about how similar and how different humans are from other animals makes up a lot of the subsequent course. Change through time The word “evolution” merely means “change through time”.

It doesn’t imply a direction, nor, does it necessarily imply improvement, merely change. In this context, evolution refers to the observation that the animals in the world have not always been the same as those that we see around us today. How do we know that this is the case? History We know that distributions of animals change. We have historical records of bears in England years ago. We find bones in caves containing lemming slide of lemming and reindeer slide of reindeer bones with no historical record of either being present here.

What Is Absolute Dating? Absolute dating is a method of determining the specific date of a paleontological or archaeological artifact or location based on a specific time scale or calendar. Scientists base absolute dating on measurable physical or chemical changes or on written records of events.

This method is the most well-known method for determining the age of fossils. Here is a simple summary of how carbon dating works. All plants and animals on Earth are made principally of carbon. During the period of a plant’s life, the plant is taking in carbon dioxide through photosynthesis, which is how the plant makes energy and grows.

Animals eat plants, and some eat other animals in the food chain. Carbon follows this pathway through the food chain on Earth so that all living things are using carbon, building their bodies until they die. A tiny part of the carbon on the Earth is called Carbon C14 , or radiocarbon. It is called ‘radio’-carbon, because it is ‘radioactive’. This means that its atomic structure is not stable and there is an uneasy relationship between the particles in the nucleus of the atom itself.

Eventually, a particle is emitted from the carbon 14 atom, and carbon 14 disappears. Most of the carbon on Earth exists in a slightly different atomic form, although it is chemically speaking, identical to all carbon.

Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.

Some misconceptions about the dating of rocks: Rocks are not dated by their appearance. Rocks are not dated by their petrologic character. Rocks are not dated by their mineralogical contents. Rocks are not dated by their structural features. Rocks are not dated by their adjacent rocks. Rocks are not dated by their vertical superposition. Rocks are not dated radiometrically. Rocks are not dated by any physical characteristics at all. Rocks are not dated by their total fossil contents. How are rocks dated: If in a strange formation and index fossil is found, it is easy to date that particular layer of rock and to correlate it with other exposures in distant regions containing the same species.

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

These are often characterised as the norm, rather than the exception.

They have their work cut out for them, however, because radiocarbon (C) dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters.

Carbon 14 also called radiocarbon, or C dating is not reliable. Here are scientific facts explaining this. This is science vs. Dating of Time in Evolution: Of over 4, quotations in the set of books this Encyclopedia is based on , only statements are by creationists. Carbon C dating was devised in Theoretically, it sounds like a good method; but, in practice, it does not turn out that way. Radiocarbon dating is only “consistent” because the large number of C dates which do not agree—are thrown out.

As with uranium and other radioactive dating, carbon dating requires flawless uniformity, down through the centuries, in regard to 13 assumptions. If one or more are incorrect, then C dating will be unreliable.

September 28th, Evolution, Not What They Once Said The armored dinosaur fossil preserved in exquisite detail unearthed in a western Canadian oil sand mine highlights the new daunting challenges facing the theory of evolution. This stunningly preserved fossil is shattering long-standing paradigms. Red Deer Valley Oil sand heavy-equipment operator, Shawn Funk pictured-left , early in the afternoon of March , was shoveling his way through the oil sands of Millennium Mine in Alberta, Canada, operated by Suncor.

After spotting a glimpse of an unexpected lump in his shovel-load of material, Funk immediately shut down his enormous workhorse. The excitement captivated Suncor. Two days later, expecting to find fossilized bones of a marine reptile, the museum team quickly realized something extraordinarily unexpected had been uncovered: After a nearly disastrous two-weeks of dust and diesel exhaust, the team successfully extracted a 15, pound rock containing the mega-fossil.
