consider the unique adaptations certain species of animals have. the scientific explanation, evolution, is completely reasonable. within a species, there will be certain mutations, or abnormalities in the offspring every so often, which of course we can see in humans (midgets), and other animals (three legged dogs). some will be useful abnormalities, others will not. if the one which is useful helps the animal to survive better than the others, then it will breed more, the others will breed less, and eventually the population will “evolve” into the new breed of the animal, better adapted to its enviroment.
There is a distinction in science between micro-evolution, and macro-evolution. What you have described above is micro-evolution; changes within a species, allowing it to adapt to different environments. CY’s example of viruses changing is also micro-evolution, as was Darwin’s observation of the differences of beak size among the birds in the Galapagos islands. No one denies that micro-evolution exists; it can be observed throughout the world, and is an undeniable fact (different breeds of dogs are another example; same species, but with variation). What has never been shown, however, is that enough micro-evolution in the same creature can change that creature into a whole new species. More “advanced” species, such as humans, are not simply repetitive rearrangements of the same simple genetic material of, say, a snail. There is actual new, different, material. So here’s a question; can you give me a single example of a small change within a species (micro-evolution) resulting in entirely new genetic material being added to the species, thus resulting in an entirely new creature?
Actually, we have pretty much proven the concept of evolution to be true, or to actually occur.
What you have proven is the existence of micro-evolution, an irrefutable concept, which is totally removed from macro-evolution (the change of one species into an entirely new species). Everything you said about bacteria and viruses is true, but proves only the existence of micro-evolution. No proof has been brought forward of the existence of macro-evolution, and I challenge you to do so.
If evolution did not occur, then where did the bones of homo erectus come from? and why dont they exist today?
In 1981, Constance Holden wrote in Science magazine “The primary evidence is a pitifully small array of bones from which to construct man’s evolutionary history. One anthropologist has compared the task to that of reconstructing the plot of War and Peace with 13 randomly selected pages.” Jonathan Wells, Icons of Evolution
Henry Gee, Chief Science Writer for Nature magazine… “No fossil is buried with its birth certificate,” he wrote in 1999, and “the intervals of time that separate fossils are so huge that we cannot say anything definite about their possible connection through ancestry and descent.” ibid
The existence of bones which, at one point an unknown amount of time ago, were a creature which does not exist today, does not prove that we must be the descendants of that creature. What it does prove, however, is that a large amount of time ago a creature which could be either a sort of ape, or a modern human with a degenerate disease, walked the earth.
Or, how come humans today are, on average, several (i think it is 3) inches taller than the humans of the 10th century?
Better eating habits and greater nourishment are the most reasonable explanations (assuming you’re correct). Would you honestly say that evolution has caused people to get taller? Heck, Americans now are taller then Americans fifty years ago were; that doesn’t make us a different species.
we can, in time, do experiments and tests to observe their validity, and decide upon or change our reasons based on the results.
What sorts of experiments can you do to prove that humans evolved from apes about 200,000 years ago?
