Good video (and worth a look for the bizarre subtitling)
These presenters have made THE common and dangerous mistake about Evolution.
Adaptation (aka "microevolution") IS a scientific fact (eg Darwin's Finches, horse evolution, peppered moths etc.) That's why dog breeders get huge variation but only ever dogs and not different kinds of animals (eg winged dogs).
However, Macroevolution (aka "microbes to man" Evolution) is entirely a different kind of Science. The science of Origins necessarily cannot be repeated in the laboratory so it will always remain a hypothesis and never a fact, whatever the evidence.
There is actually a lot of scientific evidence against Macroevolution, but because evidence FOR Microevolution is provided as evidence for Macroevolution, pupils are given the illusion that they shouldn't question Macroevolution.
It's a travesty of science that Evolution is being taught as unquestionable fact. A terrible example of this is the new Primary National Curriculum that states that the "lengthening of giraffes' necks" should be given as evidence of "evolution." It may surprise you to discover the number of giraffe fossils discovered with neck lengths shorter than the current length given that it must have taken millions of years for the giraffe's neck to evolve through mutation and natural selection. The answer is ZERO. The only scientific evidence that giraffes' necks have got longer over time is that, if Evolution is true, then they must have evolved from shorter necked giraffes. How this got into the National Curriculum as the best evidence for Evolution is a great warning to teachers not to blindly believe Richard Dawkins and other committed atheists just because they are on the telly. Also look at Truth in Science website www.truthinscience.org.uk/tis2 for an alternative viewpoint!
Blimey, you must have spent ages trawling through this forum to find this thread and then cut and paste your propaganda!
Better make sure you are tied to the ground just in case that theoretical gravity fails and you drift off into space!
It would indeed be a travesty of science if Evolution were taught as an unquestionable fact
However, Evolution needs to be taught in a manner to give the background to the questions raised and to demonstrate how observations have been built up to the theory, and how observations have helped to confirm the theory. A critical part of evolution is that it can be questioned and is robust enough to survive questioning. The value of teaching Evolution is two-fold: firstly learning about Evolution and secondly learning how scientific ideas and theories develop and progress.
And remember whilst Evolution is only a "theory", the concept that the square of length of the hypotanuse of a right angled triangle is equal to the sum of the square of the lengths of the other two sides is called Pythagoras' "Theorum" and not Pythagoras' Unquestioned Fact - but I understand that it is pretty well accepted by many people these days despite being only a theory.
You know I hear an awful lot of nonscence about these things called germs.......remember that Germ Theory is JUST A THEORY AND HASN'T BEEN SHOWN TO WORK!
Spontaneous generation ftw!
That post was worth reading for a good chuckle eh Blazer?
No, it wouldn't necessarily take 'millions of years for the giraffe's neck to evolve through mutation and natural selection'. There possibly wouldn't even be a need for mutation. The bones are the same - only longer than in other vertebrates. We could probably breed short-necked giraffes starting from the existing, long-necked stock if we tried.
If the pressure for change is high enough a change like the lengthening of the neck can take place over only a small number of generations. Think dogs and what we have done them.
A species can stay relatively unchanged for millions of years, then have a sudden adaptation over a few thousand years, then stay relatively unchanged for another million years. If the chance of finding a fossilised animal is a thousand to one, the chance of finding an intermediate stage is a million to one, since the intermediate stage can be so short time-wise.
