Was Darwin right? Are we here by chance or are we here by design, does it matter anyway, and is there conflict between science and Christianity? Dr Luke Randall, Dr Mark Toleman
Overview of the talk • What is Science? • Is there any conflict of science with religion? • Theory of evolution. • The flood and time. • Origins in the original soup? • Hereditary and mutations. • Fossils and transitions? • Devolution. • Concluding comments.
Some definitions of science Systematically acquired knowledge that is verifiable. A branch of knowledge based on objectivity and involving observation and experimentation. Systemized knowledge derived through experimentation, observation, and study. Also, the methodology used to acquire this knowledge. The job of science is to provide plausible natural explanations for natural phenomena.National Academy of science. Does science's own self-definition exclude certain theories from investigation?
Chance or design – an old debate! Water developed into other elements and these elements developed into plants, then into simple animals and finally into more complex animals like man. Thales of Miletus (640 to 546 B.C) “If there is anything in nature which the human mind, which human intelligence, energy and power could not create, then the creator of such things must be a being superior to man. But the heavenly bodies in their orbits could not be created by man. They must therefore be created by a being greater than man ……. Only an arrogant fool would imagine that there was nothing in the whole world greater than himself. Therefore there must be something greater than man. And that something must be God”. Chrysippus, c. 200 BC
Vice president of the British humanist association and a leading evolutionist in the UK, in the past has been quoted as saying:- “It is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid, or insane (or wicked, but I’d rather not consider that)” Viewpoints? From the Independent on Sunday newspaper following a school in Gateshead allowing a talk on creation:- "Last week scientists, humanists, philosophers and church liberals joined forces to denounce the Emmanuel City College in Gateshead. The school, which is backed by evangelical Christians ..... has presented creationist theories as part of their science lessons. This has to be stopped!" ‘The most devastating thing that biology did to Christianity was the discovery of biological evolution. Now that we know that Adam and Eve never were real people the central myth of Christianity is destroyed. If there never was an Adam and Eve there never was an original sin. If there never was an original sin there is no need of salvation. If there is no need of salvation there is no need of a saviour. And I submit that puts Jesus, historical or otherwise, into the ranks of the unemployed. I think that evolution is absolutely the death knell of Christianity.’ Frank Zindler, in a debate with William Lane Craig, Atheism vs. Christianity video, Zondervan, 1996.
Is science an absolute? • No Moral absolutes, but science absolute? • To not question is not science. • First century – Lungs moved blood which was constantly replaced by all organs! • 1600’s - plants only used water to grow! • To 1700 / 1800’s – belief in spontaneous generation! • 1900’s - Thymus, tonsils and appendix were considered useless leftovers but advances in cell biology enabled us to work out their functions. • Are the Theory of evolution, the big bang, all the dating methods we use etc all absolutes we should not question?

Speaking donkey Increases the widow's meal and oil Plagues of Egypt Shunammite woman's child is raised to life + lots more…….. NEW TESTAMENT The virgin birth Walking on the water The resurrection Water into wine Feeding the 5,000 The healings of Jesus The temple curtain being torn in two The apostles healings + lots more……..
Science’s conflict with creation story? Genesis creation story - All allegory / myth, or part allegory / myth or what? Not a scientific record, but what do we think? Theology in Genesis - The concept of a good loving creator, of marriage, original sin and redemption all occur in the first few chapters of Genesis. Animal kinds - In Genesis 1 it states many times that God created animals that produced offspring after their “kind”. Conflict with evolution – Time period, design rather than chance, animals produce true to kind, not unlimited change.
Analysis of Genesis text Analysis of early Genesis text shows that the ratio of Preterites to finite verbs put is as narrative text rather than poetry. From: ICR video “Thousands not millions”
Alternatives – four main views? • Molecules to man evolution by chance - No creator God, fossils laid down over millions of years? • Theistic evolution? – Old earth, fossils laid down over millions of years, local flood, some input from creator. • Progressive creationism? – Old earth, local flood?? • Literal creationism? – Young earth, literal global flood when most fossils were formed.
Darwin’s concept of natural selection • Observation 1: Offspring outnumber parents. Sometimes this is marginally the case - as when a pair of birds raise just one chick per year - but after three years, the observation becomes true. Many more animals produce large numbers of offspring - consider, for example, the number of caterpillars coming from a cabbage white butterfly, or reflect on the population of tadpoles appearing in the local pond. • Observation 2: Species numbers remain approximately constant. There are good years and bad years for all the animals we know - but we are not being overrun by robins or cabbage white butterflies or frogs. These observations lead to an: • Deduction: Observations 1 and 2 suggest that there is a struggle for survival. Some offspring die without descendants of their own. There are losers in the game of life. • Observation 3: Individuals differ in small ways, and many of these differences are inherited from parents. The observation applies to people, as we can confirm by looking at parents and children known to us. In fact, it applies to all organisms -wherever we can look closely enough. • Conclusion: Those individuals whose variations adapt them to their environment will be the most likely to survive and reproduce. This conclusion is commonly described as the principle of natural selection
Belief in evolution based on? • Spontaneous generation – still believed in to some extent in Darwin’s time • Old earth – evolution needs time, uniformitarian theory of Charles Lyell in "Principles of Geology," first published in 1830. Darwin read this on the Beagle • Fossil evidence – evidence of creatures that lived in the past • The order of fossils in the geological column • Homology (similarity) - in structures (particularly bones) and later in proteins and genes • Breeding – Darwin bred pigeons • Ability of species to adapt and selective pressure of environments • Selection of favourable characteristics • Neo Darwinism – mutations now mechanism for change
When did it all happen? • 3.5 billion years ago – first single celled prokaryotic organisms (e.g. cyanobacteria). • 2.1 billion years ago – first single celled eukaryotic organisms (e.g. like amoabae, algae) • 700 million years ago - multi-celled animals (or metazoa), jellyfish and worms • 570 million years ago - the first fishes, thetrilobites followed by nautiloids • 500 millionyears ago –corals • 438 million years ago - the first land plants • 408 million years ago - the first amphibians,insects and spiders • 360 million years ago - the amphibians were thought to develop into the reptiles • 245 million years ago - fromthe reptiles the first mammalsand dinosaurs • 208 million years ago - birds from reptiles • 144 million years ago - many reptiles died out, modern snakes and mammals • 66 million years ago - mammals spread, the first owls, shrews and hedgehogs • 58 million years ago - the first dogs, cats, rabbits, elephants and horse • 37 million years ago - the first deer, monkeys,pigs and rhinoceros • 24 million years ago - new mammals, including mice, rats and apes • 5 million years ago - Australopithecuswith the first cattle and sheep • Man made in the image of God about ?? years ago
The flood and time Dating with radio-isotopes became well established around 1925. Before that, an old age was attributed to the earth on the basis of a geological processes happening at a uniform rate, e.g. UNIFORMITATIANISM.
How long did it take to lay down these rock layers? Bottom layer, 9 hours on 18th May 1980 Middle layer 12th June 1980 Top layer – Mud flow March 1982 From AIG video: “Geological evidences for rapid strata formation.”
Erosion How long did it take for this Gorge to be eroded though volcanic rock?
Over literally hundreds of square miles of the Grand Canyon (see left) there are literally billions of nautaloid fossils (see below). Many of these nautaloids are in the rock vertically, suggesting rapid hardening of the rock. A catastrophe, rather than millions of years of gradual sediments. From AIG video: “Geological evidences for rapid strata formation.”
Polystrate trees Fossilised trees that go though supposedly millions of years of strata?
Carbon dating of coal As carbon 14 has a half life of c. 5,700 years, no coal should have any carbon 14 in it if the coal was formed millions of years ago. However, coal from different geological intervals all Has similar amounts of carbon 14, as do diamonds. From: ICR video “Thousands not millions”

Spontaneous generation 570 BC - “In the beginning there was a fish-like creature with scales that arose in and lived in the world ocean. As some of these advanced, they moved onto land, shed their scaly coverings and became the first humans.” Greek philosopher named Anaximander 1745 - John Needham, an English clergyman, proposed what he considered the definitive experiment. Everyone knew that boiling killed micro-organisms, so he proposed to test whether or not micro-organisms appeared spontaneously after boiling. He boiled chicken broth, put it into a flask, sealed it, and waited - sure enough, micro-organisms grew. Needham claimed victory for spontaneous generation and was made a fellow of the Royal society. Later work showed the corks let bacteria through. 1802 - Dr Erasmus Darwin (Darwin’s grandfather) "Hence without parents, by spontaneous birth, Rise the first specks of animated earth.“ 1953 - Dr Stanley Miller’s famous experiment. In this experiment water vapour, ammonia, methane and hydrogen was subjected to spark discharges and simple amino acids were formed. After this experiment was performed, a newspaper headline proclaimed that life had been made in a test tube! Dr Miller later admitted the problem of origins was more complex than he imagined.

How complex is a cell? "[The instructions within the DNA of a single cell] if written out would fill a thousand 600 page books. Each cell is a world brimming with as many as two hundred trillion tiny groups of atoms called molecules. . Our 46 [human] chromosome 'threads' linked together would measure more than six feet. Yet the [cell] nucleus that contains them is less than four ten-thousandths of an inch in diameter." Rick Gore, "The Awesome Worlds within a Cell" in National Geographic, September 1976, pp. 357-358, 360.
Layered stromatolite fossils produced by the activity of ancient cyanobacteria. Cyanobacteria are among the easiest microfossils to recognize. Dated at 3.5 billion years old! The first bacteria?
The First bacteria – unchanged? If at an one time, there were only 1,000,000,000 cyanobacteria (less than 1 gram of bacteria) alive on the planet, assuming they divide every 2 days (varies for different strains at different temperatures), then in 3,500,000,000 years, they must have divided 618,000,000,000,000,000,000 times without significant errors in DNA replication! The DNA of cyanobacteria has made copies of itself for 3,500,000,000 years with out enough errors to change the structures they form!
Origin of the first cell? To produce this miracle of molecular construction all the cell need do is to string together the amino acids (which make up the polypeptide chain) in the correct order………… If a particular amino acid sequence was selected by chance, how rare of an event would that be? Suppose the chain is about two hundred amino acids long; this is, if anything, rather less than the average length of proteins of all types. Since we have just twenty possibilities at each place, the number of possibilities is twenty multiplied by itself some two hundred times. This is conveniently written 20260, that is a one followed by 260 zeros! This number is quite beyond our everyday comprehension. For comparison, consider the number of fundamental particles (atoms, speaking loosely) in the entire visible universe, not just in our own galaxy with its 1011 stars, but in all the billions of galaxies, out to the limits of observable space. This number, which is estimated to be 1080, is quite paltry by comparison to 10260. Moreover, we have only considered a polypeptide chain of a rather modest length. Had we considered longer ones as well, the figure would have been even more immense." Francis Crick, [Crick received a Nobel Prize for discovering the structure of DNA.] Life Itself, Its Origin and Nature (1981), pp 51-52.
Pangenesis Darwin know nothing of genes, chromosomes, DNA, protein structure or mutations. Darwin proposed the idea of pangenesis. Cells of the body produced substances called gemmules and parts of the body that were more used produced more of these substances. These gemmules were thought to affect sex cells of the body in such a way that in the next generation, there would be enhanced development of parts of the body that produced excess gemmules and diminished development of part of the body that produced less gemmules. As science has progresses, it is more difficult to account for bacteria to man evolution than when Darwin proposed pangenesis.
Mitosis Normal cell division, two set of chromosomes in each cell. Meiosis Cell division to produce sperm or egg, shuffling around of genetic material leads to variation, coupled with acquired genes from mother and father. In 1911 the American geneticist Thomas Hunt Morgan (1866-1945) observed cross-over in Fruit flies meiosis and provided the first true genetic interpretation of meiosis.
Darwin’s finches Most of the ground finches have been show to inter-breed so are they actually different species? Beak size can vary with seasons? Actual observations of rapid finch adaptation have forced evolutionists to scale that back to a timeframe from millions of years to just a few centuries. The different types of finches reflect selection of genetic material that was there, not new material.

Do mutations produce new information? Left. Change of one DNA nucleotide is sufficient to cause sickle cell anaemia Right. Cystic fibrosis protein of 1,480 amino acids. Deletion of one of these amino acids causes cystic fibrosis
Fossil of a coelacanth Prior to 1938, the coelacanth was known only from fossils. Certain structures, such as fins, were determined to be the forerunners of legs for all amphibians. Fossils and transitions
Layered stromatolite fossils produced by the activity of ancient cyanobacteria. This process still occurs today at Shark Bay in western Australia. Living fossils - bacteria
Plants show stability over time Maple, cycads, walnut, fig, magnolia, willow, ginko tree, birch, fan palm, monkey puzzle, sea lilly, tassel fern, grape, sponges, seaweed and wollemi pine The fossil liquidambar leaf is allegedly about 20 million years old on the evolutionists’ time-scale. This specimen is from ‘Miocene’ brown coal in north-western Germany. Yet the leaves are almost identical to the living variety (right), showing no evolution. Living fossils – plants
Living fossils - insects Little change in 250 million years for dragon flies? Or for bees and spiders Amber ant Or for cockroaches and millipedes
Living fossils – aquatic creatures and reptiles Lobsters, crayfish and rays (fossils found in Jurassic rock), lampshells, molluscs, mussels, oysters, thumb nail shells (fossils found in Carboniferous rock), sharks (fossilised teeth found in Devonian rock). Also slitsnails, green sturgeon, lungfish, mackerel, perch, herring, the horseshoe crab, the coelocanth, jelly fish, frogs, toads, the nautilus, crocodiles, alligators, turtles etc. Fossil of a frog, looking very frog-like
Living fossils - mammals Dire Wolf fossils at the NationalMuseum of Natural History. Similar to modern wolf. Could Meiosis explain differences between fossilised and living mammals? Many mammals including bats (left), shrews, opossums are living fossils.
Fossils - transitions "The evidence we find in the geological record is not nearly as compatible with Darwinian natural selection as we would like it to be ....We now have a quarter of a million fossil species but the situation hasn't changed much. The record of evolution is surprisingly jerky and, ironically, we have even fewer examples of evolutionary transition than in Darwin's time ... so Darwin's problem has not been alleviated“ Evolutionist David Raup, Curator of Geology at Chicago's Field Museum of Natural History. “And we find many of them (fossilised organisms) already in an advanced state of evolution, the very first time they appear. It is as though they were just planted there, without any evolutionary history. Needless to say, this appearance of sudden planting has delighted creationists". Richard Dawkins, The Blind Watchmaker (New York: W.W. Norton Co., 1987).
Do we see evolution happening? The process of evolution must find/develop immense amounts of Information. Amoeba Amount of information Amount of information 1 book 10,000 books
Can this amount of information be found by the process of mutation And natural selection? No! observed changes via natural selection reduce information
