Debunking the myths part 2 1, Evolutionary science is not predictive well to a certain extent this is true, evolution can go down so many different paths it can be impossible to predict what turns it might take next splits in evolution can go down so many tiny initial variations, that does not however mean it cannot be predicted at all for example Darwin predicted the earth must be very old for all the life forms to have evolved, turned out to be a lot older than he imagined, he also predicted transitional fossils would be found and millions have been, even more if you count microfossils, or take the peppered moth, it evolved black colouration to adapt to pollution stained trees, now this pollution is being reversed the moth is going back to its lighter colour and for another prediction google Richard Alexander. 2, Evolution cannot be disproved so is not science To count as science, hypotheses and theories should make predictions that might turn out to be wrong there are loads of things that could disprove evolution, for example if we where to find a amphibian fossil older than the first fossilized fish, that would disprove it and there has been fraudulent claims to this effect, finding a mammal fossil feathers would also throw evolution into doubt as birds and mammals evolved from separate groups of reptiles google echidnas and archaeopteryx for examples of these two however so far everything has supported evolution, 3, Evolution is just so unlikely to produce complex life forms To get to grips with evolution you need to understand three things. 1, quadrillion-to-one chances actually happen all the time. 2,, while mutation is random, which one survives to the next round is not. 3, with time, the accumulation of one advantageous mutation after another can produce indescribably complex systems, given enough time evolution makes the apparently impossible possible Evolution is an entirely random process 4, Mutations can only destroy information, not create it Mutations can end up being very useful in nature, for example birds that just peck their food are moved to an area where the food mostly is harder nuts which need to be cracked to eat, a few of theses birds have mutations in their beaks which allows them to perform this task, the birds that cannot get enough food will die out leaving the ones with the mutations to survive and reproduce and all future generations will be hatched with the nut cracking beak @
