Somebody explain evolution to me?

From my understanding, evolution is how we evolved from a bunch of little fish or whatever and I was watching a documentary on Charles Darwin the other day and it was talking about how birds evolved to have black feathers to blend in from predators. Why don't we evolve to overcome cancer? An example of this is skin cancer. So many people have gotten it, yet we haven't evolved to adapt to the sun. Somebody please explain this to me.

    Great question - evolution's million dollar question. Evolution, however, cannot solve biological problems.

    The reason is - evolution is envisioned as an undirected processes. Therefore, health problems - like skin cancer or any other cancer or disease, have never been demonstrated to be solved by evolution.

    In fact, mutations are now known only to cause disease. Over 4,000 human diseases are the direct result of genetic mutations - not cures.

    The bird story highlights the disconnect with reality.

    Cancer has existed for millennia but it is not wide spread. Skin cancer is fairy new phenomena. If 70% or 80% of the population were to be killed by cancer then the remaining 20% "might" have a resistance to cancer. This happened with the Black Plague. 70%-80% of Europe was killed by the Black Plague, but those 20% had a CCR5 mutation that made them resistant or immune to the Black Plague. In today's world the people who descended from those who survived are resistant or immune to the flu and HIV. That is why Africa and Asia are decimated by HIV since they didn't go through the Black Plague "cleansing" and don't have the CCR5 resistance. THAT is the process of evolution. That is only a few hundred years, but do that type of thing 20 or a 100 or a 1000 times over a million years and the people who go through those events would be considerably different from those who did not go through a "Black plague" type process.

    The information that was written in the Bible that the human race came from only one family is very much scientifically true. The scattering abroad of the family of Noah in different places of the habitable earth eventually and gradually produced different physical features among them depending on the kind of environment they settled to live.

    (Acts 17:26) And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation…

    Many theories including the infamous Darwinian Theory of Evolution was taught and believed even by reputed scientists; but a fact remains — that we were created by a great God, from the first man and woman; we came from one family (not from apes); with only one language and tongue, which was later confounded by God, for His will to populate the earth with humans be fulfilled.

    (Genesis 3:20) And Adam called his wife’s name Eve; because she was the mother of all living.

    God is not the author of confusion, but is a God of order and truth.

    (1 Corinthians 14:40) Let all things be done decently and in order.

    To believe in the theory of evolution is to believe in accidents, for the theory of evolution can only be explained by accidents that allegedly happened in nature, and perhaps in the brains and minds of evolutionists!

    The human body is an adaptable organism. It can adapt even to extremes in the environment. This ability to adapt itself to a given environment helps in the ‘shaping’ of his physical body. It can be noted that there are places where natives are noticeably with long protruding noses, while the opposite is very much apparent in other places of the globe.

    The Bible desprove the theory of evolution:

    1Cor. 15:39 All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.

    Proves that the animals have the enzymes to digest grass that man cannot. His creations are as is:

    ECC. 3:14 I know that, whatsoever God doeth, it shall be forever: nothing can be put to it, nor any thing taken from it: and God doeth it, that men should fear before him.

    Do you think that who wrote the Scripture 2600yrs ago has the idea about the evolution?

    Basically a monkey lays an egg, and then you break out of the shell as a human. Its called evolution cause its quite the process. It takes days.

    We actually have evolved to adapt to the sun. Before people started moving all over the world to weird places, skin color was typically lighter the farther from the equator and darker closer to the equator where there is more sun. I am quite fair and should probably be living in the UK where there's not much sun, but I live in this habitat unnatural for my skin color called the U.S. so I have to wear sunscreen in order to not get sun burnt, sun poisoning, excessive amounts of vitamin D, etc.

    Cancer usually kills people past their reproductive age, so they've already passed down their genes before they die of cancer. Evolution only happens for things that increase reproductive fitness.

    You misunderstood. Evolution is NOT driven by what you WANT, but by survivability from a random mutation made by random chance. The black feathers meant the birds had a better survival ratio than birds without black feathers. Increased survivability. Predators killed off the other colors before they successfully passed on their genes. It was NOT because the birds wanted black feathers as you seem to think. Think about eyesight for example. Eagles and most other predators see very well. They have to, or they starve. Eyesight is critical to an eagle hunting prey. An eagle with poor eyesight, is likely to NOT live long enough to have offspring, so the poor eyesight gene does not last in the wild. The same applies to prey, such as rabbits. Rabbits that can see well, can see the eagle and hide and survive for another day, while the poor sighted rabbit gets caught by the sharp eyed eagle. Again, poor eyesight tends to die early on. Sharp eyes tend to survive longer, long enough to pass on their genes. Only MAN can override nature and DEVOLVE as we are to more and more people born needing eyeglasses. Eyesight in man is no longer a determining factor in survivability to live long enough to procreate, but it IS when it comes to eagles. THAT is what Darwin meant by "survival of the fittest" and "natural selection." Darwin was right about evolution, but wrong in HOW it works. Darwin thought evolution was serial, like links in a chain, one to the next. In fact, it is parallel, with branches forking as trees do, diverging from the main but growing in parallel. Darwin's peers discovered his error when they examined the skeletons of the birds Darwin used to base his theory on, when they found out that instead of different species as Darwin thought, the birds all turned out to be a single related strain of finch. Darwin was fooled by the outside appearance. So, we can't evolve to overcome cancer or anything else for that matter. We COULD, IF overcoming cancer meant an increase in survivability. Most cancers happen after the time when most people have children, so the genes that make it likely they will survive into the next generation. Only the survivors pass on the mutated genes which increased their survivability, which is survival of the fittest in every sense...

    This is the chicken and the egg thing... The egg MUST have come first. A close relative of the chicken as we know it, encountered a random cosmic ray, which caused a change in DNA either in the reproductive cells of the parent OR in the egg itself early on. Either way, that random ionization event completed a series of slow incremental changes and there it is, the chicken as we know it hatched from the egg AFTER the egg DNA was randomly modified by a random event, a cosmic ray.

    Cancer is caused by mutated cells that reproduce rapidly and carry their bad genes onto the daughter cells. It's probably been around for a long time and so long as we're exposed to things that could mutate our DNA (like the Sun's radiation), there's nothing evolution can do.

    P.S. If you want really good answers, re-ask this in the Biology section. That is, unless you enjoy reading the answers morons give you about how evolution is "just a theory."

    Evolution is random, as it is based on random mutations. These mutations can be beneficial or not, but the organisms with helpful ones can get more food/have more kids, etc., so those changes spread. Currently, we cannot choose to mutate to overcome a disease.

    In the American vernacular, "theory" often means "imperfect fact"--part of a hierarchy of confidence running downhill from fact to theory to hypothesis to guess. Thus the power of the creationist argument: evolution is "only" a theory and intense debate now rages about many aspects of the theory. If evolution is worse than a fact, and scientists can't even make up their minds about the theory, then what confidence can we have in it? Indeed, President Reagan echoed this argument before an evangelical group in Dallas when he said (in what I devoutly hope was campaign rhetoric): "Well, it is a theory. It is a scientific theory only, and it has in recent years been challenged in the world of science--that is, not believed in the scientific community to be as infallible as it once was."

    Well evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape-like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered.

    Moreover, "fact" doesn't mean "absolute certainty"; there ain't no such animal in an exciting and complex world. The final proofs of logic and mathematics flow deductively from stated premises and achieve certainty only because they are not about the empirical world. Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us falsely for a style of argument that they themselves favor). In science "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional consent." I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

    Evolutionists have been very clear about this distinction of fact and theory from the very beginning, if only because we have always acknowledged how far we are from completely understanding the mechanisms (theory) by which evolution (fact) occurred. Darwin continually emphasized the difference between his two great and separate accomplishments: establishing the fact of evolution, and proposing a theory--natural selection--to explain the mechanism of evolution.
