The problems with theistic evolution

Charles Darwin faced criticism from people who could not accept what they saw as his 'anti-religious' ideas. The Genesis creation story is at least 2, years old and was written when people lived completely different lives in an undeveloped environment. Answers to very difficult questions, such as how human life began, usually involved God because God was seen as the source and explanation for everything.

The study of science was then largely unknown. The Genesis stories should not be compared too closely to scientific theories. These scientific theories are much more recent. There are some, more conservative Christians who believe that the seven days of creation outlined in the Bible refers to seven long periods of time. They argue that the order in which living things were created according to the Bible may have similarities to the order scientists accept evolution took place plants, sea creatures, flying creatures, land animals and finally humans and that this makes the Bible's account more credible. Theory of evolution Evolution of human beings over millions of years from ape-like ancestors In , a British man called Charles Darwin published a book called 'On the Origin of Species'.

These reasons included: The theory of evolution seemed to go against religious teachings that God made the Earth and created all living things, as they knew them. They ate grass, they grew larger, and they ran faster because they had to escape faster predators. Because grass wears teeth out, horses with longer-lasting teeth had an advantage. For most of this long period of time, there were a number of horse types genera. Now, however, only one genus exists: the modern horse, Equus. It has teeth which grow all its life, hooves on single toes, great long legs for running, and the animal is big and strong enough to survive in the open plain.

The causes of this extinction are not yet clear. Climate change and over- hunting by humans are suggested. So, scientists can see that changes have happened. They have happened slowly over a long time. How these changes have come about is explained by the theory of evolution. In about 6, sq mi 17, km 2 , the Hawaiian Islands have the most diverse collection of Drosophila flies in the world, living from rainforests to mountain meadows.

About Hawaiian fruit fly species are known. Later adaptive radiation was caused by a lack of competition and a wide variety of vacant niches. Although it would be possible for a single pregnant female to colonise an island, it is more likely to have been a group from the same species. The combination of continental drift and evolution can explain what is found in the fossil record. Glossopteris is an extinct species of seed fern plants from the Permian period on the ancient supercontinent of Gondwana. Glossopteris fossils are found in Permian strata in southeast South America, southeast Africa, all of Madagascar , northern India , all of Australia, all of New Zealand, and scattered on the southern and northern edges of Antarctica.

During the Permian, these continents were connected as Gondwana. This is known from magnetic striping in the rocks, other fossil distributions, and glacial scratches pointing away from the temperate climate of the South Pole during the Permian. When biologists look at living things, they see that animals and plants belong to groups which have something in common.

Charles Darwin explained that this followed naturally if "we admit the common parentage of allied forms, together with their modification through variation and natural selection". For example, all insects are related. They share a basic body plan, whose development is controlled by master regulatory genes. Biologists explain this with evolution. All insects are the descendants of a group of animals who lived a long time ago.

They still keep the basic plan six legs and so on but the details change. They look different now because they changed in different ways: this is evolution. It was Darwin who first suggested that all life on Earth had a single origin, and from that beginning "endless forms most beautiful and most wonderful have been, and are being, evolved". Strong evidence for common descent comes from vestigial structures. This can be simply explained by their descent from ancestral beetles which had wings that worked. Rudimentary body parts, those that are smaller and simpler in structure than corresponding parts in ancestral species, are called vestigial organs.

Those organs are functional in the ancestral species but are now either nonfunctional or re-adapted to a new function. Examples are the pelvic girdles of whales, halteres hind wings of flies , wings of flightless birds , and the leaves of some xerophytes e. However, vestigial structures may have their original function replaced with another. For example, the halteres in flies help balance the insect while in flight, and the wings of ostriches are used in mating rituals, and in aggressive display. The ear ossicles in mammals are former bones of the lower jaw.

In , Robert Wiedersheim published a book on human anatomy and its relevance to man's evolutionary history. This book contained a list of 86 human organs that he considered vestigial. The strong grip of a baby is another example. This is borne out by the babies' feet, which curl up when it is sitting down primate babies grip with the feet as well. All primates except modern man have thick body hair to which an infant can cling, unlike modern humans. The grasp reflex allows the mother to escape danger by climbing a tree using both hands and feet. Vestigial organs often have some selection against them.

The original organs took resources, sometimes huge resources. If they no longer have a function, reducing their size improves fitness. And there is direct evidence of selection. Some cave crustacea reproduce more successfully with smaller eyes than do those with larger eyes. This may be because the nervous tissue dealing with sight now becomes available to handle other sensory input.

From the eighteenth century it was known that embryos of different species were much more similar than the adults. In particular, some parts of embryos reflect their evolutionary past. For example, the embryos of land vertebrates develop gill slits like fish embryos. Of course, this is only a temporary stage, which gives rise to many structures in the neck of reptiles, birds and mammals. The proto-gill slits are part of a complicated system of development: that is why they persisted. Another example are the embryonic teeth of baleen whales.

The baleen filter is developed from different tissue , called keratin. Early fossil baleen whales did actually have teeth as well as the baleen. A good example is the barnacle. It took many centuries before natural historians discovered that barnacles were crustacea. Their adults look so unlike other crustacea, but their larvae are very similar to those of other crustacea. Charles Darwin lived in a world where animal husbandry and domesticated crops were vitally important.

In both cases farmers selected for breeding individuals with special properties, and prevented the breeding of individuals with less desirable characteristics. The eighteenth and early nineteenth century saw a growth in scientific agriculture, and artificial breeding was part of this. Darwin discussed artificial selection as a model for natural selection in the first edition of his work On the Origin of Species , in Chapter IV: Natural selection:.

Nikolai Vavilov showed that rye , originally a weed , came to be a crop plant by unintentional selection. Rye is a tougher plant than wheat: it survives in harsher conditions. Having become a crop like the wheat, rye was able to become a crop plant in harsh areas, such as hills and mountains. There is no real difference in the genetic processes underlying artificial and natural selection, and the concept of artificial selection was used by Charles Darwin as an illustration of the wider process of natural selection. There are practical differences. Experimental studies of artificial selection show that "the rate of evolution in selection experiments is at least two orders of magnitude that is times greater than any rate seen in nature or the fossil record".

Some have thought that artificial selection could not produce new species. It now seems that it can. New species have been created by domesticated animal husbandry , but the details are not known or not clear. For example, domestic sheep were created by hybridisation, and no longer produce viable offspring with Ovis orientalis , one species from which they are descended. The best-documented new species came from laboratory experiments in the late s. William Rice and G. Each generation was put into the maze, and the groups of flies that came out of two of the eight exits were set apart to breed with each other in their respective groups.

After thirty-five generations, the two groups and their offspring were isolated reproductively because of their strong habitat preferences: they mated only within the areas they preferred, and so did not mate with flies that preferred the other areas. Diane Dodd was also able to show how reproductive isolation can develop from mating preferences in Drosophila pseudoobscura fruit flies after only eight generations using different food types, starch and maltose. Dodd's experiment has been easy for others to repeat.

It has also been done with other fruit flies and foods. Some biologists say that evolution has happened when a trait that is caused by genetics becomes more or less common in a group of organisms. Changes can happen quickly in the smaller, simpler organisms. For example, many bacteria that cause disease can no longer be killed with some of the antibiotic medicines. These medicines have only been in use about eighty years, and at first worked extremely well. The bacteria have evolved so that they are no longer affected by antibiotics anymore.

These few resistant bacteria produced the next generation. The Colorado beetle is famous for its ability to resist pesticides. Over the last 50 years it has become resistant to 52 chemical compounds used in insecticides , including cyanide. However, not every population is resistant to every chemical. Although there were a number of natural historians in the 18th century who had some idea of evolution, the first well-formed ideas came in the 19th century.

Three biologists are most important. Jean-Baptiste de Lamarck — , a French biologist , claimed that animals changed according to natural laws. He said that animals could pass on traits they had acquired during their lifetime to their offspring, using inheritance. Today, his theory is known as Lamarckism. Its main purpose is to explain adaptations by natural means. Lamarck's idea was that a giraffe's neck grew longer because it tried to reach higher up.

This idea failed because it conflicts with heredity Mendel 's work. Mendel made his discoveries about half a century after Lamarck's work. Charles Darwin — wrote his On the Origin of Species in In this book, he put forward much evidence that evolution had occurred. He also proposed natural selection as the way evolution had taken place. But Darwin did not understand about genetics and how traits were actually passed on.

He could not accurately explain what made children look like their parents. Nevertheless, Darwin's explanation of evolution was fundamentally correct. In contrast to Lamarck, Darwin's idea was that the giraffe's neck became longer because those with longer necks survived better. He proposed a theory of natural selection at about the same time as Darwin. His idea was published in together with Charles Darwin's idea.

An Austrian monk called Gregor Mendel — bred plants. In the midth century, he discovered how traits were passed on from one generation to the next. He used peas for his experiments: some peas have white flowers and others have red ones. Some peas have green seeds and others have yellow seeds. Mendel used artificial pollination to breed the peas. His results are discussed further in Mendelian inheritance. Darwin thought that the inheritance from both parents blended together. Mendel proved that the genes from the two parents stay separate, and may be passed on unchanged to later generations. Mendel published his results in a journal that was not well-known, and his discoveries were overlooked.

Around , his work was rediscovered. A set of genes are in every living cell. Together, genes organise the way an egg develops into an adult. With mammals , and many other living things, a copy of each gene comes from the father and another copy from the mother. Some living organisms, including some plants, only have one parent, so get all their genes from them. These genes produce the genetic differences which evolution acts on. Darwin's On the Origin of Species has two themes: the evidence for evolution, and his ideas on how evolution took place. This section deals with the second issue. The first two chapters of the Origin deal with variation in domesticated plants and animals, and variation in nature. All living things show variation.

Every population which has been studied shows that animal and plants vary as much as humans do. Darwin said that, just as man selects what he wants in his farm animals, so in nature the variations allow natural selection to work. The features of an individual are influenced by two things, heredity and environment. First, development is controlled by genes inherited from the parents. Second, living brings its own influences. Some things are entirely inherited, others partly, and some not inherited at all. The colour of eyes is entirely inherited; they are a genetic trait. Height or weight is only partly inherited, and the language is not at all inherited.

Just to be clear: the fact that humans can speak is inherited, but what language is spoken depends on where a person lives and what they are taught. Another example: a person inherits a brain of somewhat variable capacity. What happens after birth depends on many things such as home environment, education and other experiences. When a person is adult, their brain is what their inheritance and life experience have made it. Evolution only concerns the traits which can be inherited , wholly or partly. The hereditary traits are passed on from one generation to the next through the genes. A person's genes contain all the traits which they inherit from their parents. The accidents of life are not passed on. Also, of course, each person lives a somewhat different life: that increases the differences.

Organisms in any population vary in reproductive success. Variation can only affect future generations if it is inherited. Because of the work of Gregor Mendel, we know that much variation is inherited. Mendel's 'factors' are now called genes. Research has shown that almost every individual in a sexually reproducing species is genetically unique. Genetic variation is increased by gene mutations. DNA does not always reproduce exactly. Rare changes occur, and these changes can be inherited.

Many changes in DNA cause faults; some are neutral or even advantageous. This gives rise to genetic variation, which is the seed-corn of evolution. Sexual reproduction , by the crossing over of chromosomes during meiosis , spreads variation through the population. Other events, like natural selection and drift, reduce variation. So a population in the wild always has variation, but the details are always changing. Evolution mainly works by natural selection. What does this mean? Animals and plants which are best suited to their environment will, on average, survive better.

There is a struggle for existence. Those who survive will produce the next generation. Their genes will be passed on, and the genes of those who did not reproduce will not. This is the basic mechanism which changes a population and causes evolution. Natural selection explains why living organisms change over time to have the anatomy, the functions and behaviour that they have. It works like this:. There are now many cases where natural selection has been proved to occur in wild populations. The force of selection can be much stronger than was thought by the early population geneticists.

The resistance to pesticides has grown quickly. Resistance to warfarin in Norway rats Rattus norvegicus grew rapidly because those that survived made up more and more of the population. Mammals normally cannot drink milk as adults, but humans are an exception. Milk is digested by the enzyme lactase , which switches off as mammals stop taking milk from their mothers. The human ability to drink milk during adult life is supported by a lactase mutation which prevents this switch-off. Human populations have a high proportion of this mutation wherever milk is important in the diet. The spread of this 'milk tolerance' is promoted by natural selection, because it helps people survive where milk is available.

Genetic studies suggest that the oldest mutations causing lactase persistence only reached high levels in human populations in the last ten thousand years. Adaptation is one of the basic phenomena of biology. Adaptation is one of the two main processes that explain the diverse species we see in biology. The other is speciation species-splitting or cladogenesis. When people speak about adaptation they often mean something which helps an animal or plant survive.

One of the most widespread adaptations in animals is the evolution of the eye. Another example is the adaptation of horses ' teeth to grinding grass. Camouflage is another adaptation; so is mimicry. The better adapted animals are the most likely to survive, and to reproduce successfully natural selection. An internal parasite such as a fluke is a good example: it has a very simple bodily structure, but still the organism is highly adapted to its particular environment.

From this we see that adaptation is not just a matter of visible traits : in such parasites critical adaptations take place in the life cycle , which is often quite complex. Not all features of an organism are adaptations. If a species has recently changed its life style, a once valuable adaptation may become useless, and eventually become a dwindling vestige. Adaptations are never perfect. There are always tradeoffs between the various functions and structures in a body.

It is the organism as a whole which lives and reproduces, therefore it is the complete set of adaptations which gets passed on to future generations. In populations, there are forces which add variation to the population such as mutation , and forces which remove it. Genetic drift is the name given to random changes which remove variation from a population. Genetic drift explains how random chance can affect evolution in surprisingly big ways, but only when populations are quite small.

Overall, its action is to make the individuals more similar to each other, and hence more vulnerable to disease or to chance events in their environment. How species form is a major part of evolutionary biology. Darwin interpreted 'evolution' a word he did not use at first as being about speciation. That is why he called his famous book On the Origin of Species. Darwin thought most species arose directly from pre-existing species. This is called anagenesis : new species by older species changing. Now we think most species arise by previous species splitting: cladogenesis. Two groups that start the same can also become very different if they live in different places.

When a species gets split into two geographical regions, a process starts. Each adapts to its own situation. After a while, individuals from one group can no longer reproduce with the other group. Two good species have evolved from one. A German explorer, Moritz Wagner , during his three years in Algeria in the s, studied flightless beetles. Each species is confined to a stretch of the north coast between rivers which descend from the Atlas mountains to the Mediterranean. As soon as one crosses a river, a different but closely related species appears. This was an early account of the importance of geographical separation. Another biologist who thought geographical separation was critical was Ernst Mayr.

One example of natural speciation is the three-spined stickleback , a sea fish that, after the last ice age, invaded freshwater , and set up colonies in isolated lakes and streams.

Retrieved 25 April The most important word in the term evolutionary creation is the noun "creation". These Christian evolutionists are first and foremost thoroughly committed and unapologetic creationists. They believe that the world is a creation that is absolutely dependent for every instant of its existence on the will and grace of the Creator. The qualifying word in this category is the adjective "evolutionary", indicating simply the method through which the Lord made the cosmos and living organisms.

This view of origins is often referred to as "theistic evolution". However, such a word arrangement places the process of evolution as the primary term, and makes the Creator secondary as merely a qualifying adjective.

Meanwhile, theology had withdrawn from asserting the direct creation of the whole world by God: first to the direct creation of the human body not from the animal world ; then to that of the human soul in contrast to the human body.

Finally - it seems today - a direct intervention in the development of the world and human beings is dispensed with altogether. The English philosopher Antony Flew was unfortunately right when he stated that through this constantly repeated strategy of protection and withdrawal with which we are familiar and which for long decades kept young Catholics especially from the study of biology 'which endangers the faith' , the hypothesis of God was being 'killed by inches, the death of a thousand qualifications.
